Description

TECHNICAL FIELD [0001] The present invention relates to a plant control method using satellite information and current information,

The present invention relates to a method for controlling a plant using satellite information and current information.

In the case of operating a variety of plants, such as seawater desalination plants or power plants (hereinafter also referred to as "plants"), where seawater is taken and utilized, problems caused by harmful algae, called red tides or green tides, are intensifying.

The seawater desalination plant desalinates and treats seawater to desalinate and discharges the concentrated water. When seawater containing a large amount of red tide is taken, the desalination efficiency is lowered and the plant is adversely affected.

The power plant takes out seawater, uses it as cooling water, and discharges the discharged water. When seawater containing a large amount of red tide is taken, it will adversely affect various components in the plant separately from the cooling efficiency.

In addition, plants in marine environments where frequent red tides occur and last for a long time are affected by not only the intake but also the discharge.

In the seawater desalination plant, concentrated water with high salinity is discharged as discharged water. In the power plant, discharged water having a relatively high temperature is discharged. In any case, it is required to spread rapidly by currents at the time of discharge. However, in a marine environment where red tide is frequent and lasts for a long time, it is difficult to spread rapidly, which adversely affects the surrounding environment.

Therefore, it is required to develop a technology to prevent and prevent adverse effects in the water intake and discharge at the plant.

To this end, various researches and techniques have been developed to analyze the occurrence and severity of coastal red tides at home and abroad.

In Oman of the Middle East, the operation of some plants stopped for 55 days due to the red tide occurring in 8 months in 2008, and the production of fresh water decreased by 30 ~ 40%. With this in mind, the Center for Desalination Research in the Middle East in 2016 developed a technology to respond to the red tide of the plant using satellite information and ocean current information. However, specific red-response techniques were not disclosed.

The US Oceanic Atmospheric Administration (NOAA) provides greenhouse monitoring information every 4 hours, 6 hours a day, using satellite and ocean information. However, there is a problem that the reliability of the monitoring result is low because the offshore observation satellite uses a current model with a low resolution image once or twice a day as a polar orbiting satellite.

On the other hand, researches for solving the problem of green algae inflow into the plant are being actively carried out. The Great Lakes Environment Research Laboratory (GLERL) of NOAA in the United States is studying the plant intake manager using the satellite information and ocean information from the ocean to predict at 1km resolution every hour.

In Korea, studies on the causes of red tide are mainly conducted, and research and techniques for solving the red tide inflow to the plant have not been developed. It is difficult to predict the red tide inflow to the plant by using only satellite information, so it is necessary to use ocean current information together.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems.

Conventional red tide monitoring technology uses only satellite information, so it is impossible to predict red tide inflow to the coastal plant due to the low resolution and relatively long observation period of satellite information.

The present invention proposes a method for monitoring the influx of harmful algae such as red tide and controlling plant by using satellite information of higher resolution and shorter observation period observed by domestic Cheilian satellite, using other information. The Korean Chollian Satellite is the world's first geostationary orbit satellite, providing satellite information by monitoring the ocean around the Korean Peninsula at a resolution of 500m per day, eight times a day.

Specifically, the present invention proposes a method of predicting red tide inflow at a resolution of 500 m per day, even at the coast where the plant is located, using satellite information and current information. Ultimately, the plant site is effectively selected, To improve environmental conditions and to minimize the environmental damage caused by the plant.

If the operation control module 170 determines that the redemption possibility of the water intake zone is equal to or greater than a predetermined second reference value, the operation control module 170 controls the water intake module 210 of the plant 200 ) Of the valve (IV).

In addition, the plant 200 may further include a water intake reservoir 215. In step (f), if the redemption possibility of the water intake zone is equal to or greater than a predetermined second reference value, The operation control module 170 preferably controls the recovery rate of the fresh water treatment unit 230 of the plant 200 to be lowered.

In addition, the information collection module 110 may further collect the water quality, water temperature, flow direction, and flow rate measured information measured by the sensor S.

The present invention not only utilizes satellite information with a high spatial resolution and short observation period, but also efficiently integrates such information into an industrial field.

Through this, the plant can be effectively operated by predicting the red tide inflow. It is possible to choose plant site that can operate effectively because it has the lowest possibility of red tide among various plant planned site. Plants that are already in operation can limit or prohibit withdrawal from seawater where there is a high possibility of red tides, and prepare the medicine in advance in case the seawater containing a lot of contaminants is taken. Environmental pollution can be minimized by discharging it to the side with less pollutants.

FIG. 2 is a schematic view for explaining a method according to the present invention, in which a grating set using a magnitude scale is reflected. FIG.
3 is a conceptual diagram of a plant for explaining a method according to the present invention.

In the following, " plant " is a concept collectively referred to as a seawater desalination plant and a power plant. The seawater desalination plant collects the seawater, desalinates it, and discharges the concentrated water to the ocean. The power plant takes seawater, uses it as cooling water, and discharges it to the ocean.

In the following, "red tide" should be understood as a concept including not only red tide but also harmful tide such as green tide, organic matter, and particulate matter. That is, it is a concept that includes all materials that can be digitized using satellite information. Below is an illustration of the red tide of these substances for illustrative purposes.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, a system for performing the method according to the present invention utilizes satellite information, current information, and geographical information.

Information will be described first.

The " satellite information " is information including a plurality of gratings of a predetermined size, information of each grating, and multispectral image information of each grating. Information collected from the satellite 10, and the size of each lattice may be 500 m X 500 m. Also, satellite information is acquired per unit time, where the unit time may be one hour. Here, the size of the lattice can be smaller (i.e., the resolution can be increased), and the unit time can also be smaller. Here, the " grid information " is a criterion for classifying the positions of various grids, a current information to be described later, and a reference for synchronizing grid of geographical information and satellite information. That is, it is sufficient that the upper left corner, the lower left corner, the upper right corner and the lower right corner of each grid can be specified and synchronized. For example, it may include a radar value or a value of a rectangular coordinate system or a grid coordinate system.

The " current information " is information including a plurality of gratings of a predetermined size, information of each grating, and current vector values of each grating. As described above, the size of each grid may be 500mx500m and the size of the grid in the satellite information should be the same. The current vector value is information that is received by the current model server 20, including the direction and velocity of the current at a specific location. That is, in the current model server 20, an " current model " in which the current vector values derived from the statistical data for several years are numerically defined is pre-processed and stored. The ocean current model can be divided into a "current model", which is a model in the sea, and a "bird model", which is an offshore model. This model is referred to as an "ocean current model" It is omitted.

The " geographical information " is information including a plurality of grids each having a predetermined size, information of each grid, and whether or not each grid is in the sea and land. The size of the grid may be 500mx500m as described above and should be equal to the size of the grid in satellite information and current information. The geographical information is information previously stored in the GIS server 30. That is, in the GIS server 30, a database of information on each grid and the maritime / land status is constructed in advance, and such a database is well known and will not be described in detail. The " geographical information " may be information contained in satellite information or current information, or may include information about a plant or an artificial structure already installed on the coast.

Satellite information, ocean current information and geographical information are shown on the left side of FIG.

Geographical information is shown at the upper left of FIG. 2 and is shown with the maritime and land divisions together with a number of grids. On the coast, there may be a sea and a land together on one grid. In this case, it is preferable to look at the sea.

In the left half of FIG. 2, satellite information is shown and multi-spectral image information is shown together with a plurality of gratings.

The " multispectral image information " includes information on numerical values that are changed by at least one of the degree of chlorophyll and the degree of organic matter. More specifically, the image information confirmed at the time of the ocean observation by the satellite 10 may include color image information and multispectral image information. The multispectral image information extracted by the spectroscopic technique has different values for each grid, Chlorophyll level and organic matter level. This may be represented by an RGB value as shown in FIG. 2, or by a gray scale, or a YMCK value. In the example shown in FIG. 2, it is assumed that for the purposes of the present invention, red means higher chlorophyll and organic matter than blue. In addition, " multispectral image prediction information " means information obtained by predicting the multispectral image information.

In the bottom left of FIG. 2, the current information is shown and the current vector values along with the multiple grids are shown together as arrows. The current vector value includes the direction and size of the current, the direction of the arrow is the current direction, and the length of the arrow is the current size.

On the other hand, in another embodiment of the present invention, besides the above-described satellite information, current information and geographical information, " water quality, water temperature, flow direction, flow velocity actual measurement information "

The " water quality, water temperature, flow direction and actual flow velocity measurement information " are measured in a plurality of sensors S located in the sea and the positions (i.e., The water quality, the water temperature, the direction of flow, and the actual flow rate of the water. The sensor S located at the sea may be located in the sea part, or may be located in the ship.

On the other hand, " water quality, water temperature, flow direction, flow velocity actual measurement information " In other words, it can be obtained from multiple division and image information. However, the accuracy is lower than that measured by the sensor S and the measurement time interval is long. Therefore, in the case where the sensor S provided in the sea buoy, ship or unmanned submersible can not measure all the water quality, water temperature, flow direction and flow rate of the sea, the information obtained from the satellite 10 can be used to supplement it .

1, the controller 100 for performing the method according to the present invention includes an information collecting module 110, a real time information calculating module 120, a prediction module 130, a preliminary validity evaluation module 150, An intake control module 160, an outlet control module 180, and an information output module 190. The control module 170 controls the operation of the intake control module 170,

The control unit 100 can collect various information and control the plant 200 by predicting the influx of harmful algae such as red tide and green tide by the method according to the present invention. A desalination plant or a power plant.

The information collection module 110 collects information. Satellite information, current information, and geographical information can be collected. In another embodiment, the water quality, water temperature, flow direction, and flow rate measurement information can be further collected.

The real-time information calculation module 120 calculates real-time information using the collected information, and the prediction module 130 can further process the information to calculate the red-eye possibility information.

Here, the " real-time information " is information shown in the middle diagram of FIG. 2, which means information including both the current information and the geographical information, as well as the multispectral image information of each grid.

The preliminary validity evaluation module 150 functions to evaluate the preliminary validity of the sites of the plurality of plants 200 using the redeying possibility information.

The intake position selection module 160 functions to select the intake position of the plant 200 and the operation control module 170 performs various functions to control the operation of the plant 200. [

The discharge control module 180 functions to select a discharge position of the plant 200 and determine whether or not the discharge is performed.

The information output module 190 outputs the preliminary validity result evaluated by the preliminary validity evaluation module 150 and the intake position selected by the intake position selection module 160 to the user in the form of an image, a graph, and a table.

The plant 200 will be described with reference to Fig.

As described above, the plant 200 may be a seawater desalination plant or a power plant that receives seawater, which will be described herein as an example of a seawater desalination plant.

The plant 200 includes a water intake module 210, a pretreatment unit 220, a fresh water treatment unit 230, and a drainage module 240.

The withdrawal module 210 includes a withdrawal line IL for withdrawing seawater. The water intake line (IL) is provided with a valve (IV) for controlling whether or not to take water.

Optionally, a withdrawal reservoir 215 may further be provided at the downstream end of the withdrawal module 210. The seawater collected at the water intake module 210 is stored in the water intake storage section 215 by opening the valve IV1 toward the water intake storage section 215 and closing the valve IV2 toward the pretreatment section 220. [ The seawater stored in the water collection section 215 is transferred to the pretreatment section 220 and processed if necessary.

The preprocessing unit 220 performs a function of removing contaminants from seawater. The medicine injecting part 221 is connected to inject medicine such as a flocculant, which can be controlled by a separate valve CV1. The greater the degree of contamination, the more chemicals are injected. Any method for preprocessing may be adopted. After the treatment, the sludge is separately collected and discharged.

The wastewater generated by the pretreatment unit 220 flows to the wastewater treatment unit 225. The medicine in the medicine injecting section 221 is injected into the wastewater treatment section 225 by the separate valve CV2 to treat the wastewater. The treated wastewater (that is, the wastewater from which the sludge has been removed) is injected again into the pretreatment unit 220, and is subjected to the pretreatment and the desalination treatment, thereby raising the overall recovery rate and opening the valve WV1. Alternatively, the treated wastewater may be discharged through the drainage module 240, for which the valve WV2 is opened. Meanwhile, the sludge generated in the process of the wastewater treatment unit 225 is discharged and collected separately.

The fresh water treatment unit 230 performs a main treatment function of desalinating seawater. Reverse osmosis (RO) or positive osmosis (FO) mode, or any other method may be used. Desalinated water and wastewater are generated by the desalination treatment in the desalination treatment unit 230. The treated water is separately collected and utilized, and the wastewater is discharged through the drainage module 240.

The effluent is discharged through a drain module 240 and includes a drain line DL. The drain line DL is provided with a valve DV for controlling whether or not to discharge the water. A drain pump DP may be provided at the front end of the drainage module 240 to adjust the pressure (i.e., flow rate) of the discharge water discharged to the ocean. For example, it can be discharged at a higher speed by a drain pump (DP) control.

Alternatively, a discharge reservoir 245 may be further provided at the front end of the drainage module 240 so that the discharged water may be stored for a predetermined period of time. The discharged water stored here is discharged to the ocean at a desired time.

In the case of a power plant, both the intake module and the drain module are provided in the same manner. However, other uses using seawater instead of the fresh water treatment unit 230 will be included.

Hereinafter, a plant control method using satellite information and current information according to the present invention will be described.

First, the information collection module 110 collects satellite information, current information, and geographical information.

The real-time information calculation module 120 superimposes the collected satellite information, current information, and geographical information. When superimposed, they can be synchronized using the grid information. For example, you can use a degree of hardness.

Since the satellite information is acquired at intervals of unit time (for example, one hour) as described above, real-time information at intervals of one hour is calculated. The middle diagram of Fig. 2 shows real time information.

Next, the prediction module 130 calculates the multispectral image prediction information of each lattice after a unit time elapses by substituting the current vector information of the current information into the real-time information. It is assumed that the direction and velocity of the current vector value are constant for a unit time. The predictive information is calculated by calculating the numerical value corresponding to the multispectral image information as moving by the direction and velocity of the current vector value. The calculated predictive information can be interpreted as a value after the unit time.

The correlation between the multispectral image information, which means the degree of chlorophyll and the degree of organic matter, and the possibility of red tide is predetermined according to the prior art. In FIG. 2, as the RGB values on the multispectral image information or the multispectral image prediction information are red, the possibility of red tide is high.

The prediction module 130 can calculate the red tidability information in each grid by using such a correlation. For example, since the lattice degrees are assigned to the respective lattices, the red tidability information for each lattice degree is calculated after a lapse of a unit time.

The water intake zone in which the plant 200 receives the seawater is predetermined, so that the operation control module 170 can control the operation of the plant 200 by confirming the calculated red tide possibility for the water intake zone. Explain the specific operating method.

If the possibility of redness in the water intake zone is below the predetermined first criterion and it is relatively good, the operation is normally carried out without additional medication.

If the redemption possibility of the intake area is above the first standard, it is predicted that the contamination level of the incoming seawater will rise in the future (specifically in the future unit time, for example 3 hours in advance from now). In this case, the amount of the medicine introduced into the preprocessing unit 220 can be increased in advance. For example, if it is predicted that there is a large amount of contaminants, it is necessary to prepare the coagulant to be supplied in a larger amount. To this end, the opening degree of the valve CV1 is controlled. It is important to raise it "here in advance" here. This is because if the amount of the chemical is increased only after the contaminated sea water has been introduced, it has already adversely affected many parts of the plant 200.

It is predicted that the pollution degree of the incoming seawater will rise higher than that of the future unit time if the possibility of the redemption of the water intake zone is more than the second standard higher than the first standard. In this case, the problem caused by the contaminants in the seawater may not be solved only by the pretreatment in the pretreatment unit 220. The waste water generated after being treated in the fresh water treatment unit 230 may be excessively generated and the amount of the treated water may be small and if the fresh water treatment unit 230 uses reverse osmosis (RO) or pure osmosis (FO) The life of the membrane may be lowered or the membrane contamination problem may occur seriously. Therefore, in this case, it is preferable to control the recovery rate in the fresh water treatment section 230, which is the main treatment section, to be lowered. In other words, the flux is lowered to reduce the flow rate. If the plant 200 is a power plant, the operation efficiency is reduced.

In another embodiment, if a sufficient capacity of the catch reservoir 215 is already present or the expandable plant 200 is expected to exceed the first criterion or the second criterion, It is also possible to perform a process of closing the valve IV of the water storage tank 210 to stop the water intake and desalting the water intake storage 215 using seawater stored in advance. To this end, the valve IV2 is controlled.

As another embodiment, when the possibility of red tide is not high (i.e., when the first reference or the second reference is less than the second reference), the contamination of the wastewater treated in the wastewater treatment section 225 The valve WV2 is closed, the valve WV1 is opened, and the treatment water recovery rate is preferably increased by pretreating the valve WV1 and subjecting it to fresh water treatment. On the other hand, since the degree of contamination of the wastewater treated in the wastewater treatment section 225 is high when the possibility of red tide is high (i.e., the first reference or the second reference), the valve WV1 is closed and the valve WV2 is opened .

Even if the plant 200 is a power plant, it can operate in a similar manner using the first and second criteria.

In another embodiment, the information collecting module 110 can further collect the water quality, water temperature, flow direction, and flow rate actual measurement information measured by the sensor S, and the real-time information described above can be obtained from the water quality, And may further include information. In this case, the prediction module 130 may further calculate the water quality, water temperature, flow direction, and flow velocity prediction information of each lattice after a unit time elapses by substituting the current vector information of the current information into the real time information.

In addition, the water quality, water temperature, flow direction, and actual flow rate actual information at a position that the sensor S can not obtain can be confirmed and supplemented through the satellite 10 and can be used to calculate the water quality, water temperature, It is also possible. Control of the plant 200 through this is also possible.

When the water temperature is used, more effective control is possible in a power plant where high-temperature discharge water is discharged. In the power plant, sea water is used for cooling, and it is controlled by using water temperature prediction information rather than prediction information of red tide indicating the degree of pollution.

For example, when the plant 200 is a power plant, the operation efficiency of the plant 200 may be decreased when the water temperature is predicted to be higher than the first reference or the second reference, thereby controlling the water intake amount to be used.

Of course, in the plant 200 in which the withdrawal reservoir 215 having a sufficient capacity is already provided or can be expanded, the withdrawal amount is decreased in a state in which a large amount of seawater is taken in the withdrawal reservoir 215 in advance, It is also possible to use the seawater previously stored in the water intake storage section 215 after closing the valve IV of the water storage section 215. [

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
