A risk assessment system for hydrogen Infra-structures}

The present invention relates to a risk assessment system for hydrogen infrastructure. Specifically, when a hydrogen leak accident occurs in a hydrogen infrastructure, the hydrogen concentration, flame generation, wind direction, and wind speed information around the hydrogen infrastructure are measured and measured in real time. Using the information provided, we determine whether the hydrogen infrastructure where the hydrogen leak occurred is at risk, and 3D monitoring information on the risk of the hydrogen infrastructure judged to be at risk is generated in real time to determine the risk of the hydrogen infrastructure where the hydrogen leak occurred. This is a technology for a risk assessment system for hydrogen infrastructure that monitors the situation in real time and responds to fires and explosions caused by leaks of hydrogen gas for each hydrogen infrastructure facility.

Recently, with the development of science and technology, many industrial fields have been developed, and in particular, large-scale structures and facilities are being constructed.

When large-scale structures and facilities are constructed, the risk of safety accidents increases, and once a safety accident occurs, a large amount of damage to life and property occurs, so it is important to prevent safety accidents from occurring.

In particular, structural defects in facilities installed at industrial sites are considered to be the main cause of safety accidents occurring at industrial sites. Therefore, structural safety evaluation of facilities installed at industrial sites is conducted to check whether the facilities installed at industrial sites are structurally intact. Needs to be.

Meanwhile, as environmental pollution and global warming caused by the use of fossil fuels such as coal and oil are becoming more serious day by day, there has recently been a movement to use hydrogen, an eco-friendly fuel, instead of fossil fuels.

In other words, along with the movement to use hydrogen as a basic industrial raw material, mixed fuel for thermal power plants, automobiles, ships, and railways, there is a shift from a fossil economy based on fossil fuels to a hydrogen economy based on hydrogen that exists in countless quantities in the natural world. There is a movement to switch to .

According to this trend, hydrogen infrastructure facilities such as factories, power plants, and storage facilities are being installed and operated across the country to use hydrogen in various industries. However, due to the colorless and odorless characteristics of hydrogen, it is difficult to quickly identify leaked hydrogen. Leaked hydrogen spreads irregularly to the surroundings depending on wind direction and speed, making it difficult to quickly determine the extent of spread of leaked hydrogen, and there is a risk that it may lead to a fire or explosion due to the flammability of hydrogen.

Therefore, when a hydrogen leak accident occurs in a hydrogen infrastructure that handles hydrogen, the intensity of the leaked hydrogen gas, the spread range of the leaked hydrogen gas, rapid detection of fire or explosion caused by the leaked hydrogen gas, and accident response methods appropriate to the accident situation. It will be necessary to develop technology that presents .

The present invention is intended to solve the conventional needs and problems described above. When a hydrogen leak accident occurs in a hydrogen infrastructure facility, the hydrogen concentration, flame generation, wind direction, and wind speed information around the hydrogen infrastructure are measured in real time, and the measured information is provided. It determines whether the hydrogen infrastructure where a hydrogen leak occurred is at risk, and generates 3D monitoring information on the risk of the hydrogen infrastructure judged to be at risk in real time to determine the risk of the hydrogen infrastructure where the hydrogen leak occurred. We would like to propose a technology for a risk assessment system for hydrogen infrastructure that monitors in real time and responds to fires and explosions caused by leaks of hydrogen gas for each hydrogen infrastructure.

Embodiments of the present invention will be described in detail with reference to the attached drawings.

The present inventor's risk assessment system for hydrogen infrastructure (hereinafter referred to as the present invention) measures hydrogen concentration, flame generation, wind direction, and wind speed information around the hydrogen infrastructure in real time when a hydrogen leak accident occurs in a hydrogen infrastructure facility, and measures the measured information in real time. It is possible to determine whether a hydrogen infrastructure facility where a hydrogen leak incident occurred is in a dangerous situation and generate 3D monitoring information on the hazardous situation of the hydrogen infrastructure judged to be a hazardous situation in real time, thereby preventing hydrogen leakage from a hydrogen infrastructure facility that handles hydrogen. In the event of an accident, the intensity of hydrogen gas leakage, the spread range of leaked hydrogen gas, the effect of being able to quickly detect a fire or explosion caused by leaked hydrogen gas, and the effect of the accident situation in the event of a fire or explosion caused by a leak of hydrogen gas. It is an invention that can provide an appropriate accident response method, providing the effect of quickly responding to various types of fire and explosion accidents caused by the leakage of hydrogen gas. As shown in FIG. 1, the information collection unit 100, It is characterized in that it includes a platform server 200.

Specifically, the risk assessment system for hydrogen infrastructure of the present invention, as shown in Figure 1,

an information collection unit 100 installed in each hydrogen infrastructure to collect information on hydrogen concentration, spark generation, wind direction, and wind speed around the hydrogen infrastructure in real time and provide it to the platform server 200;

The information provided by the information collection units 100 installed in each hydrogen infrastructure is used to determine whether the hydrogen infrastructure is in a dangerous situation, and to generate and display 3D monitoring information on the hazardous situation of the hydrogen infrastructure in real time. It is characterized by including a platform server 200 installed in a remote location.

The information collection unit 100 is a component installed in each hydrogen infrastructure facility to collect hydrogen concentration, flame generation, wind direction, and wind speed information around the hydrogen infrastructure in real time and provide the information to the platform server 200.

As shown in Figure 1, hydrogen infrastructure includes power generation facilities that generate power using hydrogen gas, storage facilities that store hydrogen gas, production facilities that produce products using hydrogen gas, and charging facilities that can charge hydrogen gas. Likewise, various types of hydrogen infrastructure facilities are installed and operated throughout the country.

At this time, it is difficult to quickly identify the leaked hydrogen because it is colorless and odorless, and the leaked hydrogen diffuses irregularly to the surroundings depending on the wind direction and speed, making it difficult to quickly determine the scope of diffusion of the leaked hydrogen. Due to its flammable nature, there is a risk that leaked hydrogen may lead to a fire or explosion.

Therefore, it is necessary to quickly determine to what extent hydrogen is leaking from hydrogen infrastructure that handles hydrogen, how the leaked hydrogen is spreading, and what kind of accidents have occurred due to the leaked hydrogen before it leads to a major accident. It is possible to respond quickly. To this end, through the information collection unit 100 installed at each hydrogen infrastructure, in the event of a hydrogen leak, information on hydrogen concentration, flame generation, wind direction, and wind speed around the hydrogen infrastructure is collected in real time to form a platform. Provided by server 200.

Specifically, the information collection unit 100, as shown in FIG. 2,

A first detection module 110 that measures the hydrogen concentration around the hydrogen infrastructure in real time and provides the measured hydrogen concentration information and identification information of the hydrogen infrastructure in real time to the platform server 200;

A second detection module 120 that detects flames occurring around hydrogen infrastructure in real time and provides flame detection information and identification information of the hydrogen infrastructure in real time to the platform server 200 when a flame is detected;

Characterized by comprising a third detection module 130 that measures wind direction and wind speed around the hydrogen infrastructure in real time and provides the measured wind direction and wind speed information and identification information of the hydrogen infrastructure in real time to the platform server 200. do.

The first detection module 110 measures the hydrogen concentration around the hydrogen infrastructure in real time and provides the measured hydrogen concentration information and identification information of the hydrogen infrastructure to the platform server 200 in real time.

If hydrogen leaks from a hydrogen infrastructure, it may end up as a simple leak, but if it is a serious leak rather than a simple leak, the hydrogen concentration around the hydrogen infrastructure will gradually increase, and depending on the leaked hydrogen concentration, a subsequent fire or explosion will occur. The scale of the accident varies.

Therefore, so that the remote platform server 200 can determine the intensity of hydrogen leaking from the hydrogen infrastructure where the hydrogen leak incident occurred, the first detection module 110 measures the hydrogen concentration around the hydrogen infrastructure in real time. Measure and provide the measured hydrogen concentration information to the platform server 200 in real time.

In addition, when providing hydrogen concentration information measured by the platform server 200, identification information of hydrogen infrastructure is also provided, which means that the remote platform server 200 is installed and operated in various forms throughout the country. This is to be able to determine which of the hydrogen infrastructure facilities provides the hydrogen concentration.

The second detection module 120 detects flames occurring around hydrogen infrastructure in real time, and when a flame is detected, provides flame detection information and identification information of the hydrogen infrastructure to the platform server 200 in real time. .

If hydrogen leaks from a hydrogen infrastructure, it may end up as a simple leak, but if it is a serious leak rather than a simple leak, the hydrogen concentration around the hydrogen infrastructure will gradually increase and may lead to a fire or explosion, especially , leading to a fire incident, sparks will occur around the hydrogen infrastructure.

Therefore, so that the remote platform server 200 can determine whether a fire accident or an explosion accident occurred due to hydrogen leaked from the hydrogen infrastructure facility where the hydrogen leak occurred, the second detection module 120 is hydrogen-based. When a flame occurring around the facility is detected, flame detection information is provided in real time to the platform server 200.

In addition, when flame detection information is provided to the platform server 200, identification information of hydrogen infrastructure is also provided, which means that the remote platform server 200 is installed and operated in various forms throughout the country. The purpose is to identify which of the facilities, the flame detection information provided, is from a hydrogen-based facility.

The third detection module 130 measures the wind direction and speed around the hydrogen infrastructure in real time, and provides the measured wind direction and speed information and identification information of the hydrogen infrastructure to the platform server 200 in real time.

Hydrogen leaked from hydrogen infrastructure has the characteristic of spreading irregularly to the surrounding area depending on the wind direction and speed. The diffusion range of the leaked hydrogen varies depending on the wind direction and speed, and the method of responding to accidents also varies.

Therefore, so that the remote platform server 200 can quickly determine the extent of diffusion of leaked hydrogen, the third detection module 130 measures the wind direction and wind speed around the hydrogen infrastructure in real time and provides the measured wind direction and wind speed information. It is provided in real time through the platform server 200.

In addition, when providing wind direction and speed information measured by the platform server 200, identification information of hydrogen infrastructure is also provided, which means that many remote platform servers 200 are installed and operated in various forms throughout the country. The purpose is to identify which of the hydrogen infrastructure facilities the wind direction and wind speed information is provided from.

The platform server 200 uses information provided by the information collection units 100 installed in each hydrogen infrastructure to determine whether the hydrogen infrastructure is in a dangerous situation, and provides 3D monitoring information on the hazardous situation of the hydrogen infrastructure that is judged to be in a dangerous situation. It is a configuration that is installed remotely to generate and display in real time.

Specifically, the platform server 200, as shown in FIG. 2,

Using the information provided in real time by the information collection units 100 installed in each hydrogen infrastructure, identify the hydrogen infrastructure where a dangerous situation has occurred, and generate risk situation information of the hydrogen infrastructure where a dangerous situation has occurred in real time to create a monitoring unit (230) ) and a risk situation determination unit 210 provided by ;

Type/scale/configuration facility information for each hydrogen infrastructure facility, 3D design drawing information for each hydrogen infrastructure facility, 3D numerical analysis model information for each risk situation, statistical information on the occurrence of hydrogen leakage accidents for each facility configuration of hydrogen infrastructure, infrastructure risk grade indicator information, situational risk an information storage unit 220 in which grade indicator information is stored;

3D monitoring information on the risk situation of the hydrogen infrastructure where the risk situation occurred using the risk situation information on the hydrogen infrastructure where the risk situation occurred provided in real time by the risk situation determination unit 210 and the information stored in the information storage unit 220. It is characterized by including a monitoring unit 230 that generates and displays in real time.

The risk situation determination unit 210 uses information provided in real time by the information collection units 100 installed at each hydrogen infrastructure to identify the hydrogen infrastructure in which a risk situation has occurred, and provides risk situation information on the hydrogen infrastructure in which a risk situation has occurred. is generated in real time and provided to the monitoring unit 230. The risk situation information includes hydrogen leak intensity information, accident type information, infrastructure risk level information, wind direction and speed information, and identification information of hydrogen infrastructure.

Specifically, the risk situation determination unit 210,

Using the information provided in real time by the information collection units 100, hydrogen infrastructure that provides information with a hydrogen concentration higher than the first standard is identified as a hydrogen infrastructure in which a dangerous situation has occurred, and the hydrogen infrastructure in the hydrogen infrastructure in which a dangerous situation has occurred is identified. A hydrogen leak intensity determination module (211) that determines the leak intensity in real time as one of Small, Medium, and Large, and provides hydrogen leak intensity information and identification information of hydrogen infrastructure in which a hazardous situation occurs to the monitoring unit 230 in real time. )class,

Using the information provided in real time by the information collection units 100, hydrogen infrastructure that provides information with a hydrogen concentration higher than the first standard is identified as a hydrogen infrastructure facility in which a hazardous situation has occurred, and an accident in a hydrogen infrastructure facility in which a hazardous situation has occurred is identified. A risk type determination module 212 that determines the type of leak, fire, or explosion in real time and provides accident type information and identification information of the hydrogen infrastructure in which a dangerous situation occurs to the monitoring unit 230 in real time;

Using the information provided in real time by the information collection units 100, hydrogen infrastructure that provides information with a hydrogen concentration higher than the first standard is identified as a hydrogen infrastructure in which a dangerous situation has occurred, and the infrastructure of the hydrogen infrastructure in which a dangerous situation has occurred is identified. A risk analysis module 213 that determines the risk level and provides infrastructure risk level information and identification information of hydrogen infrastructure where risk situations occur to the monitoring unit 230 in real time;

Using the information provided in real time by the information collection units 100, hydrogen infrastructure that provides information with a hydrogen concentration higher than the first standard is identified as a hydrogen infrastructure in which a dangerous situation has occurred, and the wind direction of the hydrogen infrastructure in which a dangerous situation has occurred is identified. And a wind direction/wind speed analysis module 214 that provides wind speed information and identification information to the monitoring unit 230 in real time.

The hydrogen leak intensity determination module 211 uses information provided in real time by the information collection units 100 to identify hydrogen infrastructure in which a dangerous situation has occurred.

For example, using the information provided in real time by the information collection units 100, if the hydrogen concentration based on the hydrogen concentration information provided by the #1 hydrogen infrastructure is greater than the first standard value, the #1 hydrogen infrastructure is in a dangerous situation. It is identified as a hydrogen infrastructure where a hazardous situation has occurred, and if the hydrogen concentration according to the hydrogen concentration information provided by the #2 hydrogen infrastructure is less than the first standard, the #2 hydrogen infrastructure is identified as a hydrogen infrastructure in which no hazardous situation has occurred.

In addition, the hydrogen leak intensity determination module 211 determines in real time the hydrogen leak intensity of the hydrogen infrastructure in which a hazardous situation occurs as one of Small, Medium, and Large. When a hydrogen gas leak occurs in the hydrogen infrastructure, a simple leak occurs. It may end in , but most often it leads to a fire or explosion. Accident patterns may vary depending on the severity of the leak of hydrogen gas leaked from hydrogen infrastructure. Generally, the more severe the hydrogen leak, the higher the possibility of explosion, and the scale of damage to people or facilities is greater in explosion accidents than in fire accidents. Therefore, it is necessary to determine the extent of hydrogen gas leakage.

For this purpose, the hydrogen leak intensity determination module 211 determines the hydrogen leak intensity as Small if the hydrogen concentration is greater than the first standard value and less than the second standard value, and if the hydrogen concentration is greater than the second standard value and less than the third standard value, the hydrogen leak intensity is determined to be small. The intensity is identified as Medium, and if the hydrogen concentration is above the third standard, the hydrogen leak intensity is identified as Large.

When the hydrogen leak intensity is determined, the hydrogen leak intensity determination module 211 provides the monitoring unit 230 with hydrogen leak intensity information and identification information of the hydrogen infrastructure in which a dangerous situation occurs in real time. For example, information such as (hydrogen leak intensity: Large, hydrogen infrastructure: #1) is provided to the monitoring unit 230 in real time.

The accident type determination module 212 uses information provided in real time by the information collection units 100 to identify hydrogen infrastructure where a dangerous situation has occurred.

For example, using the information provided in real time by the information collection units 100, if the hydrogen concentration based on the hydrogen concentration information provided by the #1 hydrogen infrastructure is greater than the first standard value, the #1 hydrogen infrastructure is in a dangerous situation. It is identified as a hydrogen infrastructure where a hazardous situation has occurred, and if the hydrogen concentration according to the hydrogen concentration information provided by the #2 hydrogen infrastructure is less than the first standard, the #2 hydrogen infrastructure is identified as a hydrogen infrastructure in which no hazardous situation has occurred.

In addition, the accident type determination module 212 determines in real time the accident type of the hydrogen infrastructure where a dangerous situation occurred as one of possible leaks, fire, or explosion. If a leak of hydrogen gas occurs in the hydrogen infrastructure, it is a simple leak. It may end, but most of the time, it leads to a fire or explosion, and explosion accidents cause greater damage to people or facilities than fire accidents. Therefore, it is necessary to determine the current status of hydrogen infrastructure due to hydrogen gas leak in real time, either as a possible leak, fire, or explosion.

To this end, the accident type determination module 212 immediately determines the accident type as a leak when the hydrogen concentration exceeds the first standard value, and with the accident type identified as a leak, the information collection unit 100 detects the flame within a certain time. If detection information is provided, the risk type is re-identified as fire, and while the accident type is determined to be leakage, if the information collection unit 100 does not provide flame detection information even after a certain period of time has elapsed, the risk type is re-identified as possible explosion. do.

Generally, when a hydrogen gas leak occurs in a hydrogen infrastructure facility, a leak situation initially develops in which hydrogen gas is leaking at a certain hydrogen leak intensity (either small, medium, or large), and then the leaked gas catches fire. This can lead to a fire accident or an explosion caused by leaked gas.

Therefore, the accident type determination module 212 immediately identifies the accident type as a leak at the beginning when a hazardous situation occurs due to a hydrogen gas leak (at the point when the hydrogen concentration just exceeds the first standard value), and determines the accident type as a leak (hydrogen gas leak). In a state in which the concentration exceeds the first standard value), if the information collection unit 100 provides flame detection information within a certain time, the accident type is re-identified as fire.

As a leak situation in which hydrogen gas is leaking develops, a fire accident may occur in which the leaked gas catches fire within a certain period of time. When a fire occurs, flames from the flame exist in the surrounding area, and the information collection unit 100 When a flame caused by a flame is detected, flame detection information is provided to the platform server 200. When the information collection unit 100 provides flame detection information, the accident type determination module 212 determines the accident type as fire. It is done.

In addition, the accident type determination module 212 determines the accident type as a leak (a state in which the hydrogen concentration exceeds the first standard value) and, if the information collection unit 100 does not provide flame detection information even after a certain period of time, The accident type is re-identified as possible explosion.

As a leak situation in which hydrogen gas is leaking develops, an explosion accident may occur in which the leaked gas explodes due to some cause. When the type of accident is determined to be a leak (the hydrogen concentration exceeds the first standard value), If the information collection unit 100 does not provide flame detection information even after a certain period of time, there is a very high possibility that a large-scale explosion may occur due to leaked hydrogen gas.

Therefore, in a state where the accident type is identified as a leak (the hydrogen concentration exceeds the first standard value), if the information collection unit 100 does not provide flame detection information even after a certain period of time, a large explosion may occur due to the leaked hydrogen gas. It is identified as a situation that is very likely to lead to a leak, and the accident type determination module 212 determines the accident type as a leak (the hydrogen concentration exceeds the first standard value), and even after a certain period of time, the information collection unit 100 If no flame detection information is provided, the accident type is re-identified as a possible explosion.

Once the accident type is identified, the accident type determination module 212 provides accident type information and identification information of the hydrogen infrastructure where a dangerous situation occurred to the monitoring unit 230 in real time. For example, information such as (accident type: fire, hydrogen infrastructure: #2) is provided to the monitoring unit 230 in real time.

The risk analysis module 213 uses information provided in real time by the information collection units 100 to identify hydrogen infrastructure in which a risky situation occurs.

For example, using the information provided in real time by the information collection units 100, if the hydrogen concentration based on the hydrogen concentration information provided by the #1 hydrogen infrastructure is greater than the first standard value, the #1 hydrogen infrastructure is in a dangerous situation. It is identified as a hydrogen infrastructure where a hazardous situation has occurred, and if the hydrogen concentration according to the hydrogen concentration information provided by the #2 hydrogen infrastructure is less than the first standard, the #2 hydrogen infrastructure is identified as a hydrogen infrastructure in which no hazardous situation has occurred.

In addition, the risk analysis module 213 identifies the infrastructure risk level of the hydrogen infrastructure where a hazardous situation occurs, and the infrastructure components for each hydrogen infrastructure (e.g. Compressors, Joints, Cylinders, Hoses, Pipes, Valves, Rupture Disks, Filters, Flanges, etc.) are different, and the more infrastructure facilities there are, the higher the possibility of hydrogen gas leaking. Therefore, it is necessary to understand the infrastructure risk level of hydrogen infrastructure facilities with different infrastructure components.

To this end, the risk analysis module 213 extracts the component equipment information of the hydrogen infrastructure in which a hazardous situation has been identified from the information storage unit 220, and extracts the extracted component facility information and the hydrogen infrastructure stored in the information storage unit 220. Using the statistical information on the occurrence of hydrogen leak accidents for each facility's configuration equipment, the sum of the expected frequencies of hydrogen leak accidents of the components of the hydrogen infrastructure facility in which a hazardous situation occurred is calculated, and the calculated sum of the expected frequencies is stored in the information storage unit 220. By substituting the risk grade indicator information, the infrastructure risk grade of the hydrogen infrastructure where a hazardous situation occurs is identified.

Specifically, the risk analysis module 213 extracts information on the components of the hydrogen infrastructure in which a hazardous situation has been identified from the information storage unit 220. The information storage unit 220 contains information on the components of the hydrogen infrastructure for each hydrogen infrastructure. It is saved.

For example, if the hydrogen infrastructure in which it is determined that a hazardous situation has occurred is the #1 hydrogen infrastructure, the information storage unit 220 stores the #1 hydrogen infrastructure configuration equipment information (infrastructure configuration equipment information, for example, Compressors, Joints, Cylinders, Hoses, Pipes, Valves, Rupture Disks, Filters, Flanges, etc.) are extracted.

Meanwhile, the information storage unit 220 stores statistical information on the number of hydrogen leak accidents that occur per year for each facility constituting the hydrogen infrastructure infrastructure, which is statistical information on the occurrence of hydrogen leak accidents for each facility constituting the hydrogen infrastructure infrastructure. It is done.

For example, in Figure 3A, the number of hydrogen leak accidents that occurs in a typical compressor, which is a component of the infrastructure of hydrogen infrastructure, is 1.36, and the number of hydrogen leak accidents that occurs per year is 1.36. The number of hydrogen leak accidents that occur per year in compressors is 1.36, and the number of hydrogen leak accidents that occur in joints, which are components of the infrastructure of hydrogen infrastructure, is 2.11. The number of hydrogen leak accidents that occur per year from a typical cylinder, which is a facility, is 2.32, and the number of hydrogen leak accidents that occur a year from a typical hose, which is a component facility that makes up the infrastructure of a hydrogen infrastructure, is 1.51. The information is stored in the information storage unit 220 as statistical information on the occurrence of hydrogen leak accidents for each component of the hydrogen infrastructure.

The risk analysis module 213 uses the extracted component facility information and the hydrogen leak accident occurrence statistics for each component facility of the hydrogen infrastructure stored in the information storage unit 220 to identify hydrogen leak accidents in the components of the hydrogen infrastructure facility where a hazardous situation occurred. Calculate the sum of expected frequencies of occurrence.

For example, if the components of the #1 hydrogen infrastructure identified as having a hazardous situation extracted from the information storage unit 220 are Compressor, Joint, Cylinder, Hoses, Pipe, Valve, Rupture Disk, Filter, and Flange, By using the extracted component equipment, Compressor, Joint, Cylinder, Hose, Pipe, Valve, Rupture Disk, Filter, Flange, and the statistical information on the occurrence of hydrogen leakage accidents for each hydrogen infrastructure facility stored in the information storage unit 220, dangerous situations can be identified. Calculate the sum of the expected frequencies of hydrogen leakage accidents in the components of the hydrogen infrastructure that occurred.

Taking A in Figure 3 as an example, the sum of frequencies is 21.55. (1.36 (Expected frequency of Compressor hydrogen leak accidents) + 2.11 (Expected frequency of Joint hydrogen leak accidents) + 2.32 (Expected frequency of Cylinder hydrogen leak accidents) + 1.51 (Expected frequency of Hose hydrogen leak accidents) + 3.18 (Pipe hydrogen leak) Expected frequency of accidents) + 1.56 (Expected frequency of valve hydrogen leak accidents) + 4.23 (Expected frequency of rupture disk hydrogen leak accidents) + 1.04 (Expected frequency of filter hydrogen leak accidents) + 4.24 (Expected frequency of flange hydrogen leak accidents)

The above example is a case where there is one component facility, and if there are multiple components of the same component, the sum of frequencies increases accordingly.

Meanwhile, the information storage unit 220 stores infrastructure risk level indicator information (see B in FIG. 3), which is information that matches the risk level with the sum of the expected frequencies of hydrogen leakage incidents of facilities forming hydrogen infrastructure.

The risk analysis module 213 substitutes the calculated expected frequency sum into the infrastructure risk grade index information stored in the information storage unit 220 to identify the infrastructure risk grade of the hydrogen infrastructure in which a risky situation occurs.

Referring to B of FIG. 3, if the calculated sum of the expected frequency of hydrogen leakage incidents of the components of the hydrogen infrastructure where a dangerous situation occurred is 21.55, the infrastructure risk level is determined to be level 2.

Once the infrastructure risk level is identified, the risk analysis module 213 provides the infrastructure risk level information and identification information of the hydrogen infrastructure in which a risk situation occurs to the monitoring unit 230 in real time. For example, information such as (infrastructure risk level: level 2, hydrogen infrastructure: #2) is provided to the monitoring unit 230 in real time.

The wind direction/speed analysis module 214 uses information provided by the information collection units 100 in real time to identify hydrogen infrastructure where a dangerous situation has occurred.

For example, using the information provided in real time by the information collection units 100, if the hydrogen concentration according to the hydrogen concentration information provided by the #1 hydrogen infrastructure is greater than the first standard value, the #1 hydrogen infrastructure is in a dangerous situation. If the hydrogen concentration according to the hydrogen concentration information provided by the #2 hydrogen infrastructure is less than the first standard, the #2 hydrogen infrastructure is identified as a hydrogen infrastructure in which no hazardous situation has occurred.

When a hydrogen infrastructure in which a dangerous situation occurs is identified, the wind direction/wind speed analysis module 214 provides the monitoring unit 230 with the current wind direction and wind speed information and identification information of the hydrogen infrastructure in which a dangerous situation occurs in real time.

For example, information such as (wind direction and wind speed: no wind, hydrogen infrastructure: #1), (wind direction and wind speed: wind direction 1/wind speed 2, hydrogen infrastructure: #2) is provided in real time to the monitoring unit 230. will be.

The information storage unit 220 includes type/scale/configuration facility information for each hydrogen infrastructure facility, 3D design drawing information for each hydrogen infrastructure facility, 3D numerical analysis model information for each risk situation, statistical information on the occurrence of hydrogen leakage accidents for each component facility of the hydrogen infrastructure facility, This is a configuration in which infrastructure risk level indicator information and situational risk level indicator information are stored.

The type information for each hydrogen infrastructure is information indicating whether the hydrogen infrastructure is a power generation facility, storage facility, production facility, transfer facility, etc., and the size information for each hydrogen infrastructure represents information on the power generation/storage/production/transfer capacity of the hydrogen infrastructure. It's information.

The facility information for each hydrogen infrastructure is information about the facilities that constitute the infrastructure of the hydrogen infrastructure, for example, #1 hydrogen infrastructure (2 Compressors, 7 Joints, 2 Cylinders, 10 Hoses, 15 Pipes, 7 Valves, 3 Rupture Disks, 5 Filters, 8 Flanges), #2 Hydrogen Infrastructure (1 Compressors, 5 Joints, 1 Cylinders, 4 Hoses, 5 Pipes, 10 Valves, It may be information such as 9 Filters, 3 Flanges).

3D design drawing information for each hydrogen infrastructure facility is design drawing information for hydrogen infrastructure facilities, and is 3D design drawing information displayed in three dimensions.

The 3D numerical analysis model information for each risk situation includes 3D distribution model information of hydrogen leak intensity and leaked hydrogen concentration according to wind direction and wind speed, 3D distribution model information of fire radiant heat according to hydrogen leak intensity, wind direction and wind speed, and hydrogen leak intensity and wind direction. and 3D distribution model information of explosion pressure according to wind speed.

There are 3D numerical analysis models for various risk situations depending on the hydrogen leak intensity, wind direction and speed, and accident type. The 3D numerical analysis model for each risk situation is broadly divided into three types depending on the accident type: a 3D distribution model of leaked hydrogen concentration (if the accident type is a leak), a 3D distribution model of fire radiant heat (if the accident type is a fire), and a 3D distribution model of explosion pressure. (If the accident type is an explosion), the 3D distribution model of the leaked hydrogen concentration has a 3D distribution model of various leaked hydrogen concentrations depending on the hydrogen leak intensity and wind direction and wind speed, and the 3D distribution model of the fire radiant heat has the hydrogen leak intensity. There are 3D distribution models of various fire radiant heat according to wind direction and wind speed, and the 3D distribution model of explosion pressure may have 3D distribution models of various explosion pressures depending on hydrogen leak intensity and wind direction and wind speed.

An example of a 3D distribution model of leaked hydrogen concentration is shown in Figure 3D, and similarly, there are 3D distribution models of various types of fire radiant heat and 3D distribution models of various types of explosion pressure.

The statistical information on the occurrence of hydrogen leak accidents by facility constituting the hydrogen infrastructure is statistical information about the number of hydrogen leak accidents that occur per year for each facility constituting the infrastructure of the hydrogen infrastructure, for example, A in FIG. 3. , the number of hydrogen leak accidents that occur per year in ordinary compressors, which are components of the infrastructure of hydrogen infrastructure, is 1.36, and the number of hydrogen leak accidents that occur per year in ordinary compressors, which are components that constitute the infrastructure of hydrogen infrastructure, is 1.36. The number of occurrences of hydrogen leak accidents is 1.36, the number of hydrogen leak accidents occurring in joints, which are components of the infrastructure of hydrogen infrastructure, is 2.11, and the number of occurrences of hydrogen leak accidents that occur in joints, which are components of the infrastructure of hydrogen infrastructure, is 1 year. The number of hydrogen leak accidents that occur in a year may be 2.32, and the number of hydrogen leak accidents that occur in a typical hose, which is a component of the infrastructure of a hydrogen infrastructure, may be 1.51.

The infrastructure risk level index information is information that matches the risk level with the expected frequency of hydrogen leakage accidents of the facilities that constitute hydrogen infrastructure. Referring to B in Figure 3, the frequency agreement certain range and risk level (infrastructure risk level) This is matched, and the infrastructure risk level is a risk level due to the constituent equipment of the hydrogen infrastructure, and is a value set for each hydrogen infrastructure that does not change if there is no change in the constituent equipment of the hydrogen infrastructure.

The larger the expected frequency sum, the higher the risk level (infrastructure risk level). A large expected frequency sum means that there are many types and numbers of infrastructure components of hydrogen infrastructure or that there are many infrastructure components with frequent leaks. If there are many types and numbers of infrastructure components of hydrogen infrastructure or there are many infrastructure components with frequent leaks, the risk level (infrastructure risk level) increases as the possibility of hydrogen leaks increases.

The situational risk level indicator information is information in which the risk level (situational risk level) is matched with each combination of hydrogen leak intensity, accident type, wind direction, and wind speed. The situational risk level is the hydrogen leakage intensity, accident type, wind direction, and wind speed. The situational risk level may change at any time due to the frequently changing hydrogen leak intensity, wind direction, and wind speed.

Referring to C of FIG. 3, when combining hydrogen leak intensity, accident type, wind direction, and wind speed, numerous combination cases occur, and the information matching each combination case with the risk level (situation risk level) is used to determine the situation risk. This is grade indicator information.

For example, in Figure 3C, there may be a combination case where the hydrogen leak intensity is small, the accident type is leak, and the wind direction and wind speed are no wind. In this combination case, the risk level (situation) is There may be a combination case where the risk level (risk level) is relatively low level 1, the hydrogen leak intensity is large, the accident type is fire, and the wind direction and wind speed are wind direction 2/wind speed 3, and in this case, the situation risk level is According to indicator information, the risk level (situational risk level) may be relatively high level 4.

In other words, the risk level (situational risk level) can vary depending on the intensity of the hydrogen leak, the type of accident, and the wind direction and speed.

The monitoring unit 230 uses the risk situation information on the hydrogen infrastructure where the risk situation occurs provided in real time by the risk situation determination unit 210 and the information stored in the information storage unit 220 to It is a configuration that generates and displays risk situation 3D monitoring information of the facility in real time. The risk situation 3D monitoring information of the hydrogen infrastructure where the above risk situation occurs, which is generated and displayed in real time by the monitoring unit 230, is divided into the risk situation 3D modeling information and the final risk situation 3D monitoring information. It is characterized by including risk level information.

Below, the generation of risk situation 3D modeling information by the monitoring unit 230 will be described.

The monitoring unit 230 determines the hydrogen leak intensity information, accident type information, and wind direction of the hydrogen infrastructure where the hazardous situation occurred from the hazardous situation information on the hydrogen infrastructure where the hazardous situation occurred provided in real time by the hazardous situation determination unit 210. and wind speed information, and extract a hazardous situation 3D numerical analysis model corresponding to the identified hydrogen leak intensity information, accident type information, and wind direction and wind speed information from the information storage unit 220.

As shown in FIG. 4, the risk situation information provided in real time by the risk situation determination unit 210 includes hydrogen leak intensity information, risk type information, infrastructure risk level information, and wind direction and speed information. Using this, A 3D numerical analysis model of a hazardous situation corresponding to hydrogen leak intensity information, accident type information, and wind direction and speed information is extracted from the information storage unit 220.

For example, in Figure 4, the risk situation information provided in real time by the risk situation determination unit 210 is (hydrogen leak intensity: Medium, risk type information: fire, infrastructure risk grade: 2 levels, wind direction and wind speed: wind direction 1/ In the case of wind speed 1), (Hydrogen leakage intensity: Medium, hazard type information: fire, infrastructure risk grade: grade 2, wind direction and wind speed: wind direction 1/wind speed 1), the corresponding hazardous situation 3D numerical analysis model (D in Figure 3) reference) is extracted from the information storage unit 220.

In addition, the monitoring unit 230 identifies the hydrogen infrastructure where a dangerous situation has occurred from the risk situation information on the hydrogen infrastructure where a risky situation has occurred provided in real time by the risk situation determination unit 210, and determines the hydrogen infrastructure where a risky situation has occurred. The 3D design drawing is extracted from the information storage unit 220.

As shown in FIG. 4, the risk situation information provided in real time by the risk situation determination unit 210 includes identification information of the hydrogen infrastructure where the risk situation occurred, and the information storage unit 220 contains 3D information for each hydrogen infrastructure. Design drawing information is stored, and using this, a 3D design drawing of a hydrogen infrastructure facility in which a dangerous situation has occurred is extracted from the information storage unit 220.

For example, in Figure 4, if the hydrogen infrastructure in which the hazardous situation occurred, identified through the risk situation information provided in real time by the risk situation determination unit 210, is the #1 hydrogen infrastructure, a 3D design drawing of the #1 hydrogen infrastructure is provided. It is extracted from the information storage unit 220.

In addition, the monitoring unit 230 maps the extracted risk situation 3D numerical analysis model to the extracted 3D design drawing of the hydrogen infrastructure facility to generate risk situation 3D modeling information of the hydrogen infrastructure in which the risk situation occurred.

In other words, the generated risk situation 3D modeling information is 3D information that maps the risk situation 3D numerical analysis model to the 3D design drawing of the hydrogen infrastructure where the risk situation occurred. If the risk situation is a hydrogen gas leak, the risk situation 3D modeling information is 3D distribution model information of water concentration that indicates how the leaked hydrogen gas is distributed in the hydrogen infrastructure according to the hydrogen leak intensity, wind direction, and wind speed around the hydrogen infrastructure, and when the dangerous situation is a fire accident , The risk situation 3D modeling information is 3D distribution model information of fire radiant heat that indicates how the fire radiant heat is distributed in the hydrogen infrastructure according to the current hydrogen leak intensity, wind direction, and wind speed around the hydrogen infrastructure where the fire occurred, If the hazardous situation is a potentially explosive situation, the hazardous situation 3D modeling information is based on the current hydrogen leak intensity, wind direction, and wind speed around the hydrogen infrastructure, assuming that an explosion has occurred in a potentially explosive hydrogen infrastructure. This is 3D distribution model information of explosion pressure that shows how it is distributed in the relevant hydrogen infrastructure.

Below, the creation of final risk level information by the monitoring unit 230 will be described.

The monitoring unit 230 determines the situation risk level by substituting the hydrogen leak intensity information, risk type information, and wind direction and wind speed information from the hydrogen infrastructure where a dangerous situation occurred into the situation risk grade indicator information stored in the information storage unit 220. do.

The situational risk level indicator information stored in the information storage unit 220 is information in which the risk level (situational risk level) is matched with each combination of hydrogen leak intensity, accident type, wind direction, and wind speed, and the situational risk level is hydrogen leakage. The risk level is based on the intensity and type of accident and the wind direction and speed. The situational risk level can change from time to time due to the constantly changing hydrogen leak intensity and wind direction and speed.

Therefore, the monitoring unit 230 determines the intensity of hydrogen leakage, accident type, wind direction, and wind speed from the hydrogen infrastructure caused by the hazardous situation from the hazardous situation information provided in real time by the hazardous situation determination unit 210, and determines the The combination of the leak intensity, accident type, wind direction, and wind speed is substituted into the situation risk rating indicator information stored in the information storage unit 220, and the hydrogen leak intensity, accident type, wind direction, and wind speed of the hydrogen infrastructure issued by the hazardous situation are applied. Identify the corresponding risk level (situational risk level).

Thereafter, the monitoring unit 230 multiplies the identified situation risk level by the infrastructure risk level included in the risk situation information provided by the risk situation determination unit 210 to generate final risk level information of the hydrogen infrastructure in which the risk situation occurs. do.

For example, if the identified situation risk level is level 2 and the infrastructure risk level included in the risk situation information provided by the risk situation determination unit 210 is level 3, the final risk level of the hydrogen infrastructure where the risk situation occurred is level 6. Created with

When the risk situation 3D modeling information and the final risk level information are generated, the monitoring unit 230 displays the risk situation 3D modeling information and the final risk level information on the screen as risk situation 3D monitoring information of the hydrogen infrastructure where the risk situation occurred. As shown in Figure 5, it is displayed so that managers can monitor which hazardous situations have occurred in which hydrogen infrastructure through 3D risk situation 3D monitoring information.

Through monitoring, managers who recognize that a dangerous situation has occurred in a hydrogen infrastructure must quickly take countermeasures, and a response manual must be prepared in advance for rapid response.

To this end, the information storage unit 220 stores response plan information for each risk situation, including operation guide information for hydrogen infrastructure for each risk situation and information on evacuation routes,

The monitoring unit 230 is characterized by extracting and displaying a response plan corresponding to a hazardous situation occurring in a hydrogen infrastructure facility from the information storage unit 220.

If the dangerous situation is a simple hydrogen leak, workers at the site of the relevant hydrogen infrastructure can quickly take emergency measures to the leak, but if there is a possibility of a fire accident or explosion in the hydrogen infrastructure due to leaked hydrogen gas, a large-scale Casualties can be reduced by quickly evacuating workers on site before the accident escalates into an accident.

Therefore, if it is determined that a hazardous situation has occurred in the hydrogen infrastructure, the monitoring unit 230 provides response plan information corresponding to the hazardous situation in the hydrogen infrastructure (operation guide information and evacuation of the hydrogen infrastructure for each hazardous situation). information on the route) is extracted and displayed from the DB (220), allowing managers to quickly evacuate workers to a safe zone through information on the operation guide for hydrogen infrastructure and evacuation routes for each risk situation, and Allow necessary response measures to be taken.
