Description

Technical Field

[0001] The invention belongs to the field of electric power automation and relates to a substation debugging signal generation method and related devices. Background Art

[0002] In order to improve the lean management level of power grid equipment, the centralized monitoring system of substations has begun to be built on a large scale. The existing substations that have been put into operation need to be connected to the centralized control system. Various regions have carried out debugging and verification work on the access of existing substations to the centralized control system to ensure the correctness and consistency of the substation signals connected to the centralized control system. Aiming at the requirements of the three-remote field acceptance and debugging of the access of existing smart substations to the centralized control system, an access and debugging method supporting DL / T 860 (power industry standard) smart substations is designed. However, a large number of substations use the network 103 protocol (IEC 60870-5-103) and do not have the access and debugging conditions of DL / T 860, which increases the difficulty of their access to the centralized control system. In order to complete the debugging and acceptance without power outage, it is necessary to generate debugging signals based on the network 103 protocol through tools. Through such debugging signals, the point-to-point signal debugging between the telecontrol gateway and the centralized control system is triggered to verify whether the telecontrol point table configuration of the telecontrol gateway, the front point table of the centralized control system, the screen and database configuration are correct. Therefore, the generated debugging signals based on the network 103 protocol are the key to the point signal debugging process.

[0003] At present, simulation based on the network 103 protocol is mainly used for substation network traffic analysis. Through the structure of the substation secondary system network, data flow and message transmission rules, according to the message structure defined in the network 103 protocol, the EPOCHS (Electric Power and Communication Synchronizing Simulator) simulation platform is used to simulate the uploading process of the sudden information and periodic information of the network 103 protocol and the information processing process at the application layer. PSCAD / EMTDC (Power Systems Computer Aided Design / Electromagnetic Transients in DC Systems, a widely used power system simulation software used to simulate the steady-state and transient behavior of the power system) and NS2 (Network Simulator 2, an open source network simulation tool) are used to synchronously simulate the communication process of the measurement, control, protection and monitoring systems in the substation. The simulation results such as the average delay of the network 103 link, the end-to-end delay of the sudden information and the network load are obtained, which are used for the study of the substation network structure and communication real-time performance.

[0004] However, the simulation of the substation network 103 protocol requires accurate acquisition of the Chinese description, public address, group number, entry number, function code, information code and other information of the signal in the communication model of the simulation equipment. The simulation tool generates communication messages through the configuration information exported by the real device. The messages generated by the EPOCHS simulation platform do not need to interact with the real substation telecontrol gateway and monitoring background during use, and the correctness of the generated signal messages cannot be verified; secondly, the communication process of the measurement, control, protection and monitoring systems in the substation is simulated synchronously using PSCAD / EMTDC and NS2, which only realizes the simulation of the message traffic and data flow direction. The internal logic and behavior change rules of signal generation cannot be accurately simulated. All these lead to the debugging signals based on the network 103 protocol generated by this scheme cannot be officially used in the acceptance work of the on-site access of the existing substation to the centralized control system, and cannot meet the point-to-point signal debugging requirements when the existing substation is connected to the centralized control system.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0036] See also Figure 1 In one embodiment of the present invention, a method for generating a substation debugging signal is provided, specifically, a method for generating a simulation debugging signal for performing remote signal pairing when a substation is connected to a centralized control system.

[0037] Specifically, the substation debugging signal generation method of the present invention comprises the following steps:

[0038] S1: Obtain the communication message and monitoring point table of the substation, and generate a telecontrol signal data baseline model of the substation according to the communication message and monitoring point table of the substation.

[0039] S2: Obtain the dispatching channel telecontrol point table of the substation, and obtain the secondary equipment communication model of the substation telecontrol signal according to the dispatching channel telecontrol point table and the monitoring point table of the substation, and generate the substation debugging signal according to the dispatching channel telecontrol point table of the substation and the secondary equipment communication model of the telecontrol signal.

[0040] S3: Based on the substation debugging signal, the simulated telecontrol signal is obtained by simulating the secondary equipment, and the simulated telecontrol signal is verified according to the telecontrol signal data baseline model to obtain the correctness verification result of the substation debugging signal.

[0041] The method for generating a substation debugging signal of the present invention first directly collects the communication message of the substation, and then generates a telecontrol signal data baseline model of the substation according to the communication message and monitoring point table of the substation, directly adopts the characteristic parameters of the real operation signal, and can truly reflect the signal characteristics of the actual system; secondly, by obtaining the dispatching channel telecontrol point table of the substation and the communication model of the secondary equipment to which the telecontrol signal belongs, and establishing a correlation between the two to generate a simulation substation debugging signal, it is achieved that the signal description and telecontrol point number of the substation debugging signal are consistent with those of the actual secondary equipment signal, and an accurate source is provided for the generation of the substation debugging signal; finally, based on the substation debugging signal, a simulated telecontrol signal is obtained by simulating the secondary equipment, and the simulated telecontrol signal is checked according to the telecontrol signal data baseline model, and based on the consistency comparison between the substation debugging signal and the actual operation signal, the correctness of the substation debugging signal is checked, and the substation debugging signal after verification can ensure consistency with the on-site operation signal, and provides a correct substation debugging signal for the non-stop debugging of the old substation connected to the centralized control system, and supports the point-to-point debugging of the substation connected to the centralized control system.

[0042] In a possible implementation manner, the generation of the telecontrol signal data baseline model of the substation according to the communication message and monitoring point table of the substation includes: parsing the communication message of the substation to obtain the message characteristic parameters of the telecontrol signal of the substation; wherein the message characteristic parameters include the telecontrol point number, information description, function code, information code, public address, group number, entry number, change range, response time, change cycle, signal accompaniment law, timestamp and signal source; obtaining the monitoring characteristic parameters of the telecontrol signal of the substation according to the monitoring point table; wherein the monitoring characteristic parameters include information description, function code, information code, the secondary equipment to which it belongs and the IP address of the secondary equipment to which it belongs; associating the message characteristic parameters and monitoring characteristic parameters of the telecontrol signal of the substation to obtain the preliminary baseline model of the telecontrol signal of the substation, and assigning a unique baseline label to each telecontrol signal with the timestamp as the label on the basis of the preliminary baseline model of the telecontrol signal to obtain the telecontrol signal data baseline model of the substation.

[0043] Explanatory, see Figure 2 In order to obtain the communication message of the substation, an optional method is to connect the debugging workstation to the network switch of the substation, and then query the IP address of the substation telecontrol gateway connected to the network switch, and then capture the communication messages sent and received by the IP address. For example, the network 103 message is used as an example for explanation in this embodiment.

[0044] By parsing the communication message of the substation, the message characteristic parameters of the substation's telecontrol signal are obtained, which usually include telecontrol point number, information description, function code, information code, public address, group number, item number, change range, response time, change cycle, signal accompaniment law, timestamp and signal source and other parameters.

[0045] Explanatory, the monitoring point table of the substation can be exported on the substation monitoring background. Through the monitoring point table of the substation, the monitoring characteristic parameters of the substation's entire signal can be obtained, usually including information description, function code, information code, secondary equipment and IP address of the secondary equipment.

[0046] Regarding the message characteristic parameters and monitoring characteristic parameters of the telecontrol signal of the associated substation, exemplarily, the collected telecontrol signal of the substation is indexed with information description, function code and information code, and the corresponding signal is found in the monitoring point table, and the information description of the corresponding signal, the secondary device to which it belongs and the IP address of the secondary device to which it belongs are extracted, and the telecontrol point number, function code, information code, public address, group number, item number, change range, response time, change cycle, signal accompanying law, timestamp and signal source and other parameters are supplemented to obtain the preliminary baseline model of the telecontrol signal of the substation. Then, based on the preliminary baseline model of the telecontrol signal of the substation, a unique baseline label is assigned to each telecontrol signal collected at the current timestamp to record the baseline state of the telecontrol signal at different timestamps, and finally form the telecontrol signal data baseline model of the substation.

[0047] In a possible implementation manner, the method of obtaining the secondary equipment communication model of the substation based on the dispatching channel remote control point table and the monitoring point table of the substation includes: parsing the dispatching channel remote control point table to obtain the information description of the remote control signal of the substation; according to the information description of the remote control signal of the substation, obtaining the secondary equipment to which the remote control signal of the substation belongs and the IP address of the secondary equipment to which the remote control signal of the substation belongs by searching the monitoring point table; according to the secondary equipment to which the remote control signal of the substation belongs and the IP address of the secondary equipment to which the remote control signal of the substation belongs, establishing a link with the secondary equipment to which the remote control signal of the substation belongs through simulation software, and calling online the secondary equipment communication model of the secondary equipment to which the remote control signal of the substation belongs.

[0048] Optionally, the generation of the substation debugging signal according to the dispatching channel remote control point table of the substation and the communication model of the secondary equipment to which the remote control signal belongs includes: parsing the dispatching channel remote control point table to obtain the remote control point number and information description of the substation remote control signal; parsing the communication model of the secondary equipment to which the remote control signal belongs to obtain the model characteristics of the substation remote control signal; wherein the model characteristics include information description, public address, group number, entry number, function code and information code; and generating the substation debugging signal by associating the remote control point number and model characteristics of the remote control signal of the substation through the information description.

[0049] Explanatory, see Figure 3 , export the dispatch channel telecontrol point table on the telecontrol gateway of the substation, decompose the combined signal therein, parse the dispatch channel telecontrol point table to obtain the information description and telecontrol point number of the telecontrol signal sent by the substation to the dispatch system, and the correspondence between the combined signal and the sub-signal.

[0050] Then, according to the information description of the telecontrol signal of the substation, the secondary device and the IP address of the telecontrol signal of the substation can be obtained by searching the monitoring point table. Then, the secondary device and the IP address of the telecontrol signal of the substation are linked to the secondary device of the telecontrol signal of the substation through the simulation software. For example, in this method, the network 103 protocol simulation software is used to establish a link with the secondary device of the telecontrol signal of the substation, and the communication model of the secondary device of the telecontrol signal is called online. Then, the communication model of the secondary device of the telecontrol signal is parsed to obtain the model characteristics of the telecontrol signal of the substation, which usually includes information description, public address, group number, item number, function code and information code.

[0051] On this basis, the telecontrol point number and model characteristics of the telecontrol signal of the associated substation are described by information, and the substation debugging signal is generated, including the telecontrol point number, information description, public address, group number, item number, function code and information code. Exemplarily, the substation debugging signal can be in a sequence, that is, the substation debugging signal can be generated multiple times at a time according to the demand and combined into a sequence according to the order of the debugging demand.

[0052] In a possible implementation, the method of obtaining a simulated telecontrol signal by simulating secondary equipment based on the substation debugging signal, and verifying the simulated telecontrol signal according to the telecontrol signal data baseline model to obtain the correctness verification result of the substation debugging signal includes: the simulation software simulates the secondary equipment to which the substation debugging signal belongs to obtain the simulated secondary equipment, and imports the substation debugging signal into the simulated secondary equipment to obtain the simulated telecontrol signal; obtains the message characteristic parameters of the simulated telecontrol signal; wherein the message characteristic parameters include the telecontrol point number, information description, function code, information code, public address, group number, entry number, change range, response time, change cycle, signal accompaniment law, timestamp and signal source; with the timestamp as the section and the information description, function code and information code as the index, the simulated telecontrol signal is compared with the telecontrol signal data baseline model to obtain the comparison result; when the comparison result is that the deviation is within the preset normal margin, the correctness verification result of the substation debugging signal is passed; when the comparison result is that the deviation is outside the preset normal margin, the correctness verification result of the substation debugging signal is failed.

[0053] For example, see Figure 4 , run the signal verification software in the substation monitoring background standby machine, connect the simulated secondary equipment by starting the network 103 client program, collect the simulated telecontrol signals sent by the simulated secondary equipment in real time, and parse and obtain the message characteristic parameters of the simulated telecontrol signals, which usually include telecontrol point number, information description, function code, information code, public address, group number, entry number, change range, response time, change cycle, signal accompaniment law, timestamp and signal source.

[0054] Then, with the timestamp as the section, and the signal description, function code and information code as the index, the parameters of the collected simulated telecontrol signal are compared with the pre-established telecontrol signal data baseline model to check the correctness of the generated substation debugging signal. Specifically, by comparing the consistency of the parameters such as the change range, response time, change cycle, signal accompaniment law and signal source of the simulated telecontrol signal and the corresponding telecontrol signal data baseline model under the normal margin, the correctness check result of the substation debugging signal corresponding to the preset normal margin is determined to be failed, and the correctness check result of the substation debugging signal corresponding to the preset normal margin is determined to be failed, so as to ensure the correctness of the substation debugging signal finally used, and thus meet the signal debugging point-to-point requirements of the actual substation access to the centralized control system.

[0055] In a possible implementation, when the substation debugging signal correctness check result is failed, it also includes: generating an alarm signal for indicating that the substation debugging signal correctness check failed; verifying the correctness of the simulated secondary equipment configuration and re-simulating, and obtaining a re-simulated telecontrol signal based on the re-simulated simulated secondary equipment, and re-simulating the telecontrol signal based on the telecontrol signal data baseline model to obtain a secondary correctness check result of the substation debugging signal.

[0056] Explanatory, see Figure 4 When the correctness check result of the substation debugging signal fails, an alarm signal indicating that the correctness check of the substation debugging signal fails is first generated to inform the technicians that the correctness of the current substation debugging signal is in doubt and further verification of the problem is required.

[0057] On this basis, the configuration problem of the simulated secondary equipment is also considered. Therefore, the correctness of the configuration of the simulated secondary equipment is checked and re-simulated. Then, the re-simulated telecontrol signal is obtained according to the re-simulated simulated secondary equipment, and the telecontrol signal is re-simulated according to the telecontrol signal data baseline model. The secondary correctness verification result of the substation debugging signal is obtained, and the substation debugging signal is re-verified to improve the accuracy of the result. In view of the current situation that the existing old substations need to be connected to the centralized control system without power outages, and the existing signal verification scheme is only applicable to substations supporting DL / T 860, the old substation signal simulation technology using the network 103 protocol relies on third-party software, and the correctness of the simulation signal lacks verification means, which cannot meet the actual operation of the substation The point-to-point signal debugging requirements of the access to the centralized control system, the substation debugging signal generation method of the present invention generates a data baseline model by collecting real operating signals, reads the communication model configuration of the secondary equipment, generates a substation debugging signal for point-to-point debugging of the centralized control system, and finally uses the data baseline model to verify the generated substation debugging signal to ensure the accuracy of the generated substation debugging signal.

[0059] See also Figure 5 In another embodiment of the present invention, a substation debugging signal generating system is provided, which can be used to implement the above-mentioned substation debugging signal generating method.
