Description

Technical Field

[0001] The present invention relates to the technical field of relay protection, and in particular to an information-based relay protection fixed value risk management and control platform with high reliability. Background Art

[0002] Relay protection device is one of the important equipment in the power system. An accurate and appropriate relay protection setting scheme plays a key role in the safe and stable operation of the power system and the selectivity and sensitivity of the protection action.

[0003] In the power system, relay protection devices play a vital role. When a fault occurs in the power system, it can act quickly and accurately to cut off the faulty part to protect the safe and stable operation of power equipment and systems. The correct setting of the relay protection setting is the key to ensure that the relay protection device can play its due role. If the setting is unreasonable, it may cause the protection device to malfunction or refuse to operate, which will bring serious consequences to the power system. Therefore, it is also necessary to control the risk of relay protection setting to ensure that the relay protection device can operate when the circuit fails. Generally, the relay protection setting needs to be set through precise calculations, and the relay protection setting needs to be optimized and adjusted when the power system is running. Data on the power system and relay protection devices can only be viewed from a fixed platform client. For a relatively large power system, it is difficult to view circuit data anytime and anywhere and deal with fault risks in a timely manner, and safety needs to be further improved. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an information-based relay protection setting risk management and control platform with high reliability.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A highly reliable information-based relay protection fixed value risk management and control platform, including a data acquisition terminal, a server terminal, a remote control terminal, a fixed value calculation terminal, a fixed value debugging terminal, a determination module, a real-time monitoring terminal, a response terminal, a fixed value optimization terminal and an emergency processing improvement terminal;

[0007] The data acquisition terminal is used to collect parameters and operation data of power equipment in the power system and various data of relay protection devices in real time;

[0008] The server end is connected to the data collection end, and the data collection end sends the collected data to the server end via a wireless network;

[0009] The remote control terminal is connected to the server via a wireless network, and multiple remote control terminals are provided, and different remote control terminals are granted different IP addresses;

[0010] The fixed value calculation terminal is used to obtain various data and calculate the relay protection fixed value according to the data;

[0011] The fixed value debugging terminal is used to simulate various situations according to the calculated relay protection fixed values;

[0012] The determination module is used to access the server side, and the server side retrieves the circuit operation data from the database, the data including normal state operation data and abnormal state operation data, and divides the relay protection risk degree according to the abnormal state operation data;

[0013] The real-time monitoring terminal is used to obtain and monitor the data and conditions of the power system and relay protection devices in real time;

[0014] The response end is connected to the real-time monitoring end, and after the determination module determines the risk level, the fault conditions are sorted according to the level of risk level;

[0015] The setting value optimization terminal is used to analyze the reasons why the relay protection setting value has risks after the risk processing is completed, and calculate or adjust the relay protection setting value according to the analysis results;

[0016] The emergency handling improvement terminal is used to generate a risk report after the risk handling is completed, and send it to the server, store it synchronously in the database, analyze the risk report, and improve the risk emergency plan according to the risk level, fault type and risk handling operation measures.

[0017] Preferably, the data acquisition terminal monitors and collects real-time operating data of the power equipment through power equipment monitoring equipment, and the collected data is transmitted through a wireless network.

[0018] Preferably, after receiving the various data collected by the data collection end, the server end synchronizes the data to a database, and the database can store the various data in a structured storage manner.

[0019] Preferably, different remote control terminals are granted different IPs, and different IPs grant different permissions, such as reading data, modifying data, deleting data, etc. The remote control terminal can send instructions to the server through a wireless network, and the server then processes the instructions and then feeds the information back to the remote control terminal. When the remote control terminal is connected to the server, it is authenticated by a security authentication device. Only users who pass the authentication can perform remote control operations. Identity authentication can be verified in a variety of ways, such as user name and password, digital certificate, biometrics, etc.

[0020] Preferably, the constant value calculation end considers the operation mode of the power grid under various conditions when calculating the constant value, including the normal operation mode of the circuit and the possible abnormal operation mode of the circuit, to ensure that the relay protection constant value can adapt to a variety of possible operation modes and can operate correctly when an abnormal situation occurs.

[0021] Preferably, the set value debugging terminal checks whether the relay protection device can operate correctly. During simulation, after ensuring that the relay protection set value can adapt to various abnormal situations, the relay protection set value is entered into the relay protection device.

[0022] Preferably, when the determination module divides the risk degree of relay protection according to the abnormal state operation data, the risk degree is divided into low risk, medium risk and high risk respectively. When the risk degree is low risk, it means that the deviation of the relay protection setting is small, and the impact on the operation of the power system is small, and no processing is required. When the risk degree is medium risk, it means that the deviation of the relay protection setting will affect the normal operation of the local power system and needs to be adjusted. When the risk degree is high risk, it means that the relay protection setting is unreasonable and needs to be processed in a timely manner.

[0023] Preferably, once the real-time monitoring terminal finds that the power system or the relay protection device is in an abnormal state, it transmits various data collected by the data collection terminal during the abnormal state to the determination module for risk determination.

[0024] Preferably, when the response end sorts the fault conditions according to the level of risk, the high risk is sent in the order of medium risk, and medium risk is sent in the order of low risk. After the risk condition is sent to the remote control end through the wireless network, emergency response plans are set in advance for different degrees of risk, and when a risk occurs, the corresponding emergency response plan is sent and the processing task is sent on the basis of granting operational permissions to different remote clients.

[0025] Preferably, after recalculating and adjusting the set value, the set value optimization end simulates various situations through the set value debugging end to ensure that the relay protection device can operate correctly under fault conditions.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention collects the parameters and operation data of power equipment in the power system and various data of the relay protection device in real time through the data acquisition end, sends them to the server end through the wireless network, and synchronizes them to the database, so as to ensure the security of data storage and realize data sharing. The fixed value calculation end calculates the relay protection fixed value according to the data, and the fixed value debugging end simulates various situations according to the calculated relay protection fixed value to check whether the relay protection device can operate correctly and ensure the accuracy of the fixed value calculation. The judgment module accesses the server end, and the server end retrieves the data of the circuit operation from the database, and divides the relay protection risk degree according to the abnormal state operation data. The real-time monitoring end obtains and monitors the power system and the relay protection device in real time. Once it is found that the power system or the relay protection device is in an abnormal state, the various data collected by the data acquisition end in the abnormal state are transmitted to the judgment module for risk judgment. After the judgment module judges the risk degree, the fault situation is sorted according to the level of risk degree. The risks are sent in the order of high risk first, medium risk first, and medium risk first, low risk first, to ensure that high-risk faults can be handled in a timely manner. After the risk situation is sent to the remote control end through the wireless network, emergency response plans are set in advance for different degrees of risk, and when a risk occurs, the corresponding emergency response plan is sent on the basis of granting operable permissions to different remote clients to ensure that the risk can be handled in a timely manner. After the risk is handled, the reasons for the risk of relay protection settings are analyzed, and based on the results of the analysis, the relay protection settings are calculated or adjusted. After the risk is handled, a risk report is generated and sent to the server, stored in the database synchronously, and the risk report is analyzed. According to the risk level, the type of fault situation and the risk handling operation measures, the risk emergency plan is improved to ensure that when dealing with similar abnormal situations, effective measures can be taken quickly to deal with them, thereby improving the safety of the power system and the reliability of the relay protection device in the later stage.

[0028] Figure 1 This is a schematic diagram of the framework of a highly reliable information-based relay protection setting risk management and control platform proposed by the present invention. DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1 , a highly reliable information-based relay protection fixed value risk management and control platform, including a data acquisition terminal, a server terminal, a remote control terminal, a fixed value calculation terminal, a fixed value debugging terminal, a judgment module, a real-time monitoring terminal, a response terminal, a fixed value optimization terminal and an emergency processing improvement terminal;

[0031] The data collection terminal is used to collect the parameters and operation data of the power equipment in the power system and various data of the relay protection device in real time. The data collection terminal monitors and collects the real-time operation data of the power equipment through the power equipment monitoring equipment, and the collected data is transmitted through the wireless network;

[0032] The server side is connected to the data collection side. The data collection side sends the collected data to the server side through the wireless network and synchronizes it to the database. The database can store the data in a structured storage method to ensure the independence of data storage;

[0033] The remote control terminal is connected to the server through a wireless network. By setting up multiple remote control terminals, different remote control terminals are granted different IPs, and different IPs are granted different permissions, such as reading data, modifying data, deleting data, etc. The remote control terminal can send instructions to the server through the wireless network, and the server will then process the instructions and then feed back the information to the remote control terminal. When the remote control terminal is connected to the server, it is authenticated by a security authentication device. Only users who pass the authentication can perform remote control operations. The identity authentication can be verified in a variety of ways, such as user name and password, digital certificate, biometrics, etc.

[0034] The fixed value calculation terminal is used to obtain various data and calculate the relay protection fixed value based on the data. When calculating the fixed value, the operation mode of the power grid under various conditions is considered, including the normal operation mode of the circuit and the possible abnormal operation mode of the circuit, to ensure that the relay protection fixed value can adapt to various possible operation modes and can operate correctly when abnormal conditions occur;

[0035] At the setting value debugging end, various situations are simulated according to the calculated relay protection setting values ​​to check whether the relay protection device can operate correctly. During the simulation, after ensuring that the relay protection setting values ​​can adapt to various abnormal situations, the relay protection setting values ​​are entered into the relay protection device;

[0036] The judgment module is used to access the server side. The server side retrieves the data of the circuit operation from the database. The data includes normal state operation data and abnormal state operation data. The risk level of the relay protection is divided into low risk, medium risk and high risk according to the abnormal state operation data. When the risk level is low risk, it means that the deviation of the relay protection setting is small, and the impact on the operation of the power system is small, and no processing is required. When the risk level is medium risk, it means that the deviation of the relay protection setting will affect the normal operation of the local power system and needs to be adjusted. When the risk level is high risk, it means that the relay protection setting is unreasonable and needs to be processed in time.

[0037] The real-time monitoring terminal is used to obtain and monitor the data and conditions of the power system and relay protection device in real time. Once the power system or relay protection device is found to be in an abnormal state, the data collected by the data acquisition terminal in the abnormal state will be transmitted to the judgment module for risk judgment;

[0038] The response end is connected to the real-time monitoring end. After the determination module determines the risk level, the fault conditions are sorted according to the risk level, and sent in the order of high risk taking precedence over medium risk, and medium risk taking precedence over low risk. After the risk situation is sent to the remote control end through the wireless network, emergency response plans are set in advance for different levels of risk, and when a risk occurs, the corresponding emergency response plans are sent based on the operable permissions granted to different remote clients to handle the task;

[0039] The setting value optimization terminal is used to analyze the reasons for the risk of the relay protection setting value after the risk treatment is completed, and calculate or adjust the relay protection setting value according to the analysis results. After recalculating and adjusting the setting value, multiple situations are simulated through the setting value debugging terminal to ensure that the relay protection device can operate correctly under fault conditions;

[0040] The emergency handling improvement terminal is used to generate a risk report after the risk is handled, send it to the server, store it synchronously in the database, analyze the risk report, and improve the risk emergency plan based on the risk level, type of fault situation and risk handling operation measures to ensure that effective measures can be taken quickly to deal with similar abnormal situations.

[0041] When the present invention is running, the data acquisition end collects the parameters and operation data of the power equipment in the power system and various data of the relay protection device in real time, and the collected data are sent to the server end through the wireless network and synchronized to the database. The fixed value calculation end obtains various data and calculates the relay protection fixed value according to the data. The fixed value debugging end simulates various situations according to the calculated relay protection fixed value to check whether the relay protection device can operate correctly. The judgment module accesses the server end, and the server end retrieves the data of the circuit operation from the database. The data includes normal state operation data and abnormal state operation data. The relay protection risk degree is divided according to the abnormal state operation data. The real-time monitoring end obtains and monitors the power system and the relay protection device in real time. Once it is found that the power system or the relay protection device is in an abnormal state, the various data collected by the data acquisition end in the abnormal state are transmitted to the judgment module for risk judgment. After the determination module determines the risk level, it sorts the fault conditions according to the risk level and sends them in the order of high risk before medium risk and medium risk before low risk. After the risk situation is sent to the remote control terminal through the wireless network, emergency response plans are set in advance for different levels of risk, and when a risk occurs, the corresponding emergency response plan is sent on the basis of granting operable permissions to different remote clients. After the risk is processed, the reasons for the risk of relay protection settings are analyzed, and based on the results of the analysis, the relay protection settings are calculated or adjusted. After the risk is processed, a risk report is generated and sent to the server, stored synchronously in the database, and the risk report is analyzed. According to the risk level, the type of fault situation and the risk handling operation measures, the risk emergency plan is improved to ensure that effective measures can be taken quickly to deal with similar abnormal situations.
