Description

Energy Efficiency Management System {ENERGY EFFICIENCY MANAGEMENT SYSTEM}

The present invention relates to an energy efficiency management system for a facility such as a building, and more particularly, to an energy efficiency management system for a facility (building, etc.) incorporating FMS (Facility Management System) and energy management. will be.

There is a need for systematic management in managing facilities represented by buildings and the like. In the past, there was no structured management technique in the construction phase of the facility and the subsequent use phase. However, as facilities have become larger and more complex, there has been a growing awareness that simply building them does not work well, and the concept that emerges is the Facility Management System (FMS).

Facility Management System (FMS) technology stores configuration information, performance information, operator information, fault information, and various detailed information of all equipment that needs control, and checks whether there is a problem with the equipment, and sends a message to the operator regarding the problem of the equipment. to provide. In addition, it receives the control command of the equipment based on the error message from the operator to control the equipment. Operators receive messages and provide control commands over the wireless Internet, allowing operators to manage their facilities without having to monitor them all the time.

Recently, large organizations such as Hanaro Telecom, Hynix Semiconductor, and LG Electronics, as well as public institutions such as Gyeongsangbuk-do Office of Education and Daegu Office of Education have introduced FMS.

A related concept is BAS (Building Automation System or Building Automation System). The development of the management system industry is also linked to the BAS to develop the building's BAS. In 1970, buildings became very tall and large, and consequently, the complexation and systemization of electric power facilities, air conditioning facilities, and disaster prevention facilities progressed rapidly. It is applied as a building automatic control system (BAS).

In addition, with the advent of computers, BAS developed rapidly, and BAS was installed in small buildings according to the purpose of building. According to BAS's computerization, BAS's Remote Station (RS) transmission trunk was connected to the telephone line to connect multiple buildings in the local and remote areas, so that management due to the concentration of alarms and driving began before. It is a prototype of the BAS, and nowadays, the distributed control system with the main concept of “centralization of management and decentralization of control” has become the mainstream of BAS. Other building facilities can be operated and managed remotely from the military management center by accessing the Internet.

FMS or BAS is about the basic setting or control method for the management of the building, and it is unclear what the management (or basic control) of the building is based on (or basic data). The criteria would not be clearly set. For example, the criteria may be arbitrarily set even if performed manually or automatically.

Buildings (buildings / facilities, etc.) are becoming increasingly tall and large, and moreover, the concept of 'u-City (ubiquitous City)' requires energy efficiency management of the entire city. New buildings are being constructed including an energy efficiency management system in consideration of energy efficiency, but existing buildings / facility are urgently required for a system for energy efficiency management. It is important to note that 75 to 80 percent of the energy consumption in the life cycle of a building is consumed during maintenance phases, such as facility management.

Currently, FMS systems that operate buildings and facilities are not widely used, and in particular, the concept of efficiently operating FMS systems in connection with energy efficiency management systems is difficult to establish.

First of all, from the technical point of view, domestic energy-related management technology is in a weak state, and is emerging recently due to the energy policy of information, and the energy efficiency management system related to buildings / facility is suitable for domestic environment. There is no energy efficiency management system.

If energy efficiency management of buildings / facilities is separate from the FMS system, the probability of staying at the level of simple monitoring is too high. It is much more efficient to analyze and manage the energy efficiency of buildings by linking basic and maintenance history information of buildings, facilities and equipment of FMS systems with energy information.

In other words, building / facility, utility (water, electricity, gas, etc.) baseline information is automatically collected by existing operation management without separate data collection activities, and energy saving factors are detected by fusion with energy-related data collected in real time. give.

Therefore, building energy information collection, analysis, and evaluation are the basic functions.In this way, the information DB (database) on facility management of FMS system and the DB of energy efficiency management system are converged to support energy management efficiently.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram illustrating the present invention.

The present invention has the basic functions of collecting, analyzing, and evaluating building energy information, and in this way, it is possible to efficiently manage energy by fusing an information database on facility management of a facility management system (FMS) system and a database of an energy efficiency management system. To help.

In FIG. 1, the FMS 101 stores configuration information, performance information, operator information, failure information, and various other detailed information of predetermined equipment that needs control in a facility (eg, a building) to check for abnormality of equipment. Check and provide a message to the operator according to the equipment. In addition, it is possible to control the equipment by receiving a control command of the equipment based on the error message from the operator.

Energy baseline 102 refers to the baseline or limit line of energy use in the facility. In other words, as a guideline for the use of energy for the facility as a guideline, such as the daily electricity consumption to some extent, the daily gas consumption to some extent (of course, can be divided into monthly, quarterly, yearly, etc.) The energy baseline 102 is not determined uniformly every day, but is preferably variable according to the day of the week or season. Energy, but is not limited to this typically means power, heat, gas, water, oil, and the like supplied to the facility.

In addition, the energy baseline 102 is designed to distribute or consume energy sources (electric power, heat, gas, water, oil, etc.) by dividing them into the concept of zone targets (groups, buildings, floors, offices). desirable.

The energy consumption source 103 may be a lamp, a heater, a cooler or the like. The energy consumption source 103 may be referred to as a device that consumes energy (power, heat, gas, water, oil, etc.).

As shown in FIG. 1, these energy consumption sources 103 are connected to the BAS 104, the remote meter reading 105, and various facilities 106. The BAS 104 refers to a building automation system, in which a computer is applied to the operation, control, and management of a building facility. The remote meter 105 is to enable to remotely measure the amount of energy consumed by the energy consumption source (103). That is, in order to find out the gas consumption of the building, it is common to go directly to the building and look at the gas consumption meter and record the value. However, according to the remote meter reading 105, the usage value of the gas consumption meter can be checked at other places. . This may be possible, for example, via wired / wireless communication. In addition, there are various facilities 106, which may be similar to the energy consumption source 103 or may be additionally present in the energy consumption source 103. For example, when the lamp is an energy consumption source 103, a timer for the lamp may be viewed as various fixtures 106. Alternatively, the various installations 106 may also be viewed as being widely included in the energy consumption source 103.

Next, raw data acquisition is performed. Raw data acquisition is performed by the Energy Data Acquisition Module (EDAM) 107, which constitutes an energy information database. That is, the baseline information database is configured using the energy baseline, which may be related to buildings, facilities, energy efficiency classes, energy systems, and the like.

The energy data acquisition module 107 (EDAM) corresponds to the step (or module) of constructing an energy information database, and may also correspond to the step (or module) of configuring a baseline information database. The baseline information may be information about a building, a facility, an energy efficiency class, an energy system, a zone, and the like.

The energy baseline includes information about energy sources (i.e. power, heat, gas, water, oil, etc.), information about zones (i.e. military, buildings, floors, offices, etc.), information about equipment. And the like.

In addition, as the information handled in the energy data acquisition module 107, as the energy use information, information on the total usage of energy, the usage by energy source / area / equipment, baseline, target (target value, planned value) and the like can be processed. have.

The role of the energy data acquisition module 107 is to narrowly grasp the energy consumption at the energy consumption source 103, and to broadly acquire (possibly process) data of the energy baseline 102. can do.

Then, data VRG application 108 is performed. VRG means Validation, Reconciliation, and Gross Error Detection. The data VRG application 108 performs appropriate correction on the raw data acquired by the EDAM 107. it means. The reason for correcting the raw data is to select only valid data from the collected data and to process it into meaningful information in the system. Examples of the data VRG (correction) include equipment, metering time error correction for each DDC, and coinciding with the standard metering time.

This corrected data 109 is then used in the EBMM 110 Energy Baseline Mapping Module. The energy baseline mapping module 110 creates energy maps of baseline and performance data fused with FMS information and provides energy efficiency information.

Energy mapping means mapping at least performance data (data of the amount of energy actually used; see FIG. 5 to be described later) in correspondence with an energy baseline. In one embodiment, the energy baseline mapping module 110 takes into account performance data, energy baseline, and plan data (predetermined conditions such as occurrence of a special situation based on the energy baseline, which will be described later with reference to FIG. 5). Reference) may be mapped to each other.

The energy baseline mapping module 110 of FIG. 1 corresponds to a step (or module) of creating and providing an energy map to a user. In this module 110, baseline energy efficiency ratings, energy sources, energy regions, equipment maps, etc. are created, and energy baseline mapping operations are performed. Through work in this module 110, a comprehensive information map analysis and provision of energy sources, regions, equipment, and out weather can be performed.

An example of the energy baseline mapping will be described later with reference to FIG. 5.

In the EEATM 111 of FIG. 1, energy efficiency analysis is performed through energy efficiency auto-tracking using energy baseline and mapping data.

The energy efficiency automatic tracking module 111 of FIG. 1 automatically detects inefficient elements based on the energy baseline mapping. The module 111 may provide information, such as what to reduce and what to adjust in order to be efficient consumption by area and equipment for inefficient elements. In addition, the module 111 can perform a utility check history, an operating time, a comprehensive analysis of the external environment, and the like.

Automatic detection / tracking of these inefficiencies (utilities) is based on, for example, tracking based on energy sources, tracking based on energy domains, tracking based on equipment, tracking based on utility history, and benchmarking. There may be a trace, a trace based on the utility power factor, or a trace based on a particular piece of equipment.

An example of automatic energy efficiency tracking will be described later with reference to FIG. 6 (a).

Data passing through the EBMM 110 and EEATM 111 of FIG. 1 includes the EMM 112 (Energy Monitoring Module), the EAM 113 (Energy Analysis Module), and the EEM 114 (Energy Efficiency Module). And energy efficiency information modules to provide easy reporting that can be easily analyzed even by specialists or non-professional building / facility management operators.

The energy monitoring module 112 corresponds to a step or module for monitoring energy information by a user. This allows you to see the usage by energy source (i.e. power (power / light / heating), heat, gas, water) or the energy usage by energy area (group / building / floor / cross-section (office)). Various types of monitoring can be performed, such as energy usage by equipment and facilities, and total usage, area usage, usage against baselines, and usage against targets (plans). do.

In other words, energy monitoring (total amount, energy-specific, etc.) may be performed on building energy (power, water, gas, oil), more specifically power monitoring (power, lighting, etc.), equipment Monitoring (air conditioners, heaters, etc.) may be done.

The energy analysis module 113 is a step or module for analyzing and providing energy information to a user. Analytical information can be provided via graphics or reports. The collected information can be classified and managed by category to provide an effective energy management tool. In addition, it is desirable to analyze and provide comprehensive information for each energy source, area, equipment, and out weather.

The energy efficiency module 114 measures and provides information on the energy efficiency of the equipment / facility. Provides analytical information on improving efficiency by inefficiency equipment / facility. In addition, it is desirable to provide a basis for operating simulation of equipment / facility through energy efficiency analysis.

The main function of the module 114 is to provide energy efficiency information for each facility / equipment. Specifically, the efficiency of each building equipment is measured, a foundation for plant / plant optimization operation is established, and comprehensive information of inefficient equipment / equipment is provided. Can be provided. It can also measure FMS fusion equipment / facility energy efficiency and provide usage time, baseline specifications, history, operating methods, and the like.

An example of providing energy efficiency information will be described later with reference to FIG. 6 (b).

In FIG. 1, the energy monitoring module 112, the energy analysis module 113, and the energy efficiency information module 114 are conceptually divided (that is, 'monitoring' and 'analysis' and 'efficiency information calculation' of energy are separated. In some cases, their functions may be somewhat fused. That is, even though the energy analysis module 113 is used, if the analysis is broadly regarded as including the calculation of efficiency information, the function of the energy efficiency information module 114 may be performed in a range that does not impair the essence of the invention. Of course, it may be used.

Figure 2 (a) is a flow chart illustrating the steps of the present invention, Figure 2 (b) is a variant of the system of the present invention.

In step 201 of FIG. 2A, the information of the FMS system 101 and the baseline 102 information of the energy efficiency management system are fused to generate a verified fusion database 109 that has undergone the correction procedure 108.

In step 202, energy monitoring 112 is performed based on the verified data 109 to provide energy information in real time.

In step 203, the energy performance is analyzed 113 against the energy plan and evaluation information is provided.

In operation 204, an energy map is generated through the energy baseline mapping module 110 to provide energy efficiency information.

In step 205, the energy efficiency automatic tracking module 111 provides the energy efficiency automatic tracking information using the energy mapping information.

Alternatively, step 202 and / or step 203 may be performed after step 205 or in parallel with step 204/205.

In other words, with respect to step 201, fusion with FMS information is one feature, which is fusion of facility management system (FMS) information and energy information, and may have a baseline configuration that is the basis of energy map construction. have.

In addition, in relation to step 201, the data verification / correction performs the validity of the collected data, the verification and the selection of the data, and processes and corrects the data into meaningful data and information in the system (for example, for each facility / DDC). Meter time error correction, reference time matching, etc.).

In connection with step 204, the energy baseline mapping maps a baseline database fused with FMS information and historical (real-world) data energy.

In relation to the steps 203, 203, and 205, the energy efficiency analysis enables automatic energy efficiency tracking through energy baseline mapping information, and enables energy efficiency analysis and energy saving.

In addition, the step 202 is related to monitoring and reporting, it is desirable to provide a user-centric data monitoring and report management, and to provide a tool that can be easily manipulated even non-experts.

On the other hand, Figure 2 (b) is almost similar to Figure 1, but the flow of the corrected data 109 is slightly different, in Figure 1 the corrected data is the energy baseline mapping module 110 and / or energy efficiency automatic tracking Although shown as being analyzed 113 only after going through the module 111, it is not necessarily limited thereto. For example, in FIG. 2B somewhat differently from the diagram of FIG. 1, the corrected data 109 may be directly monitored 113 (ie, corresponding to step 202 of FIG. 2A) and corrected. The analyzed data may be analyzed 112 after passing through the energy baseline mapping module 110 and / or the energy efficiency automatic tracking module 111.

In addition, rather than necessarily limited to Figs. 1 and 2 (b), it is preferable to grasp the flow of data to some extent.

For example, referring to the steps 201 to 205 and FIG. 2B, various flowcharts may be derived. For example, (a) a state of equipment included in a predetermined facility by the energy data acquisition module. Energy Baseline 102 for obtaining Facility Management System (FMS) 101 information, including information or historical information, and presenting guideline values of energy usage for the equipment targeted by the Facility Management System 101 information. Obtaining), and using the facility management system (101), acquiring historical data which is actual energy use data for equipment targeted for the facility management system (101); (b) mapping, by the energy baseline mapping module 110, the historical data in correspondence with the energy baseline 102; And (c) automatically detecting an inefficiency in energy usage by comparing the mapped historical data with the energy baseline 102 by the energy efficiency automatic tracking module 111. have.

Of course, the corrected performance data may be used as the performance data.

In addition, as described above, the monitoring by the energy monitoring module 112 may be performed between the steps (a) and (b), or may be performed after the step (c). In this case, the result may be slightly different.

3 is a diagram illustrating the hardware architecture of the system of the present invention.

The FMS server 301 represents the above-described FMS system 101 differently. The FMS server 301 is responsible for facilities, equipment history, standard work, and the like.

There is also an energy efficiency management server 302.

It can be seen that HVAC (Heating, Ventilating & Air Conditioning) server and ELEC server (electric / power control server) exist in the building automatic control system 304 (BAS). The building automatic control system 304 corresponds to the BAS 104 of FIG. 1. For example, it can be seen that the HVAC server is connected to a cooling tower, a boiler, an air conditioner, a pump, a refrigerator, and the like through an Ethernet LAN. In addition, it can be seen that the ELEC server is connected to an extra high voltage plate, a high voltage plate, a low platen, an MCC, lighting / heating, and the like through an Ethernet LAN to control power. Although it is said to be connected via an Ethernet LAN, this is one example, for example, may be connected by a wireless method such as Wi-Fi or WiBro.

The remote metering target equipment 305 performs power SCADA, gas metering, water metering, oil metering, power metering, and the like, which corresponds to the remote metering meter 105 of FIG.

The facility DCS interface 306 is an interface for controlling various power plants, boilers, cooling towers, compressors, and the like. That is, the facility DCS interface 306 may be regarded as an interface for controlling the various devices 106 of FIG. 1.

The FMS server 301, the energy efficiency management server 302, the building automatic control system 303, the remote meter reading target equipment 305, and the facility DCS interface 306 are connected to the user 303 through TCP / IP Ethernet. have. The user 303 represents a terminal of the user. It is said that the predetermined data can be confirmed through this terminal, any type of electronic equipment may be sufficient, and it will be a PC or a dedicated terminal normally. On the other hand, they are said to be connected via TCP / IP Ethernet, but this is an example, it may be connected to other types of networks, for example, Wi-Fi or WiBro, such as a wireless way to send and receive data.

4 illustrates the software architecture of the system of the present invention.

The FMS 101 at the lower right of FIG. 4 uses environment variables, benchmark data, etc., and has data on facility information and facility history.

It is connected to the energy data acquisition module 107, which not only receives energy related data from the FMS 101, but also includes scheduling, remote control, communication error management, protocol handling, and the like. do.

The energy data acquisition module 107 (EDAM) corresponds to the step (or module) of constructing an energy information database, and may also correspond to the step (or module) of configuring a baseline information database. The baseline information may be information about a building, a facility, an energy efficiency class, an energy system, a zone, and the like.

The energy baseline includes information about energy sources (i.e. power, heat, gas, water, oil, etc.), information about zones (i.e. military, buildings, floors, offices, etc.), information about equipment. And the like.

In addition, as the information handled in the energy data acquisition module 107, as the energy use information, information on the total usage amount of energy, the usage amount by energy source / area / equipment, baseline, target, etc. may be processed.

Data from the FMS 101 or data obtained by the energy data acquisition module 107 from the FMS 101 is subjected to the data VRG 108 (data verification, correction, and total error detection), and the data has been verified and corrected. Is processed in the energy baseline mapping module 110.

The energy baseline mapping module 110 corresponds to a step (or module) of creating and providing an energy map to a user. In this module 110, baseline energy efficiency ratings, energy sources, energy regions, equipment maps, etc. are created, and energy baseline mapping operations are performed. Through work in this module 110, a comprehensive information map analysis and provision of energy sources, regions, equipment, and out weather can be performed.

An example of the energy baseline mapping will be described later with reference to FIG. 5.

The energy efficiency automatic tracking module 111 of FIG. 4 automatically detects inefficient elements based on the energy baseline mapping. The module 111 may provide information, such as what to reduce and what to adjust in order to be efficient consumption by area and equipment for inefficient elements. In addition, the module 111 can perform a utility check history, an operating time, a comprehensive analysis of the external environment, and the like.

Automatic detection / tracking of these inefficiencies (utilities) is based on, for example, tracking based on energy sources, tracking based on energy domains, tracking based on equipment, tracking based on utility history, and benchmarking. There may be a trace, a trace based on the utility power factor.

An example of automatic energy efficiency tracking will be described later with reference to FIG. 6 (a).

The real-time database, history database, benchmark database 401, electric / power database, heating database 402, etc., located at the upper end of FIG. 4 are configured to exchange data with the aforementioned energy efficiency automatic tracking module 111. It is preferable.

These data can be represented via a graphical user interface 403 (GUI) as at the top right of FIG. 4. Viewable through the GUI 403 may be, for example, real-time data, benchmarking data, reports / trend graphs, environment variables, and the like.

Inefficient utilities (resources, factors) can be detected by sending and receiving such data, for example, comparing utility maintenance history and consumption, comparing uptime and consumption by utility, and consumption by utility of the same specification. Can be compared or the like.

5 is a diagram illustrating an example of energy baseline mapping.

Energy baseline mapping is based on energy sources (ie, by classification of power, heat, gas, water, oil, etc.), by area (ie, by classification of military, building, floor, zone, etc.) and equipment. Therefore, guidelines are set according to peak demand according to power factor.

In FIG. 5, an example of power mapping is shown. A diamond line in a solid line represents a baseline. In other words, the standard targets for power usage, midnight usage, daytime usage, nighttime usage, power factor, and peak values are set.

And, the line with the square shape in the solid line means the plan. The plan may be thought to be similar to the baseline, or to distinguish it from the baseline, considering the situation in more detail. In other words, the plan data is data based on the energy baseline, but modified on the energy baseline according to a predetermined condition. For example, there may be a baseline for August, which is a typical midsummer, and, for example, if a heat wave alert is issued in a particular state, for example, the baseline is considered in consideration of such a specific situation (ie heat wave alert). We make some modifications to create a mapping criterion called "plan."

In addition, a line with a triangular shape embedded in the solid line indicates performance. Performance is actually the amount using the said energy (in the example of FIG. 5).

In the example of FIG. 5, it can be seen that the baseline is about 100, the plan is about 110, and the performance is about 120. In addition, you can compare baselines, plans, and performance for late night usage and weekly usage to easily understand how energy is being used. The measure of usage and the measure of late-night usage may differ. In other words, the value of one scale in the usage item should not be the same as the value in the night use item, but it is preferable to be different from each other for easy visual confirmation, and it is preferable to base the scale so that the baseline or plan generally draws a regular hexagon. It is more preferable to adjust.

On the other hand, the diamond-shaped graphic as shown in Figure 5 is an example of the visual representation of the energy baseline, it is not necessarily to be represented graphically or to be represented in the shape as shown in FIG.

6A is a diagram illustrating an example of automatic tracking of energy efficiency.

6 shows an example of automatic tracking of the efficiency of the refrigerator, in which the efficiency of the first refrigerator is indicated to be good, and the efficiency of the second refrigerator is indicated to be in a serious state (not good).
