Description

Technical Field

[0001] This invention relates to the field of substation remote signaling information acceptance, specifically a substation remote signaling dual-platform synchronous automatic acceptance system and method. Background Technology

[0002] Currently, in the power grid sector, substation acceptance requires monitoring from both the centralized control system and the smart grid dispatching system. For newly built or renovated substations, their remote signaling information needs to be accepted before related equipment is integrated into the centralized power grid monitoring system. Conventional acceptance methods require on-site acceptance personnel to verify the accuracy of remote signaling information via real-time telephone communication with the main station acceptance personnel. Since each monitoring platform uses dual-channel communication, acceptance personnel need to perform multiple verifications on each remote signaling information across two platforms and four planes. This process is slow and inefficient, preventing substations from being put into operation on time and impacting power grid safety. Improving the speed at which substation remote signaling information can be quickly accessed by both platforms has significant practical and application value, but a satisfactory solution has not yet been found. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention provides a system and method for simultaneous automatic acceptance testing of remote signaling information of equipment in newly built or renovated substations using both smart grid dispatching and centralized control systems.

[0004] The technical solution adopted in this invention is: a substation remote signaling dual-platform synchronous automatic acceptance system, including a smart grid dispatching system and a centralized control system, and further including:

[0005] The information table management system stores information tables related to the remote signaling commissioning of substations.

[0006] The main station automatic acceptance platform includes an information table management module and an information comparison module. The main station automatic acceptance platform connects upward to the information table management system and downward to the smart grid dispatching system and centralized control system.

[0007] The data communication gateway connects to the smart grid dispatching system and centralized control system at the top, and to the measurement and control devices at the bottom.

[0008] The telemetry and control device is manually operated to send remote signaling signals and upload them to the data communication gateway.

[0009] Preferably, the data communication gateway verifies the correctness of the remote signaling configuration.

[0010] Preferably, the master station automatic acceptance platform further includes a smart grid dispatch system database reading module and a centralized control system database reading module.

[0011] Preferably, there are multiple measurement and control devices, which are numbered from 1 to n, where n is a positive integer.

[0012] Preferably, the main station automatic acceptance platform also includes an acceptance report module for generating acceptance reports.

[0013] Preferably, the acceptance report module formats and typeset the acceptance qualified signals to form an acceptance report, and provides the original information of the smart grid dispatch system database and the centralized control system database for the acceptance unqualified signals.

[0014] A method for synchronous automatic acceptance testing of a substation remote signaling dual-platform system includes the following steps:

[0015] (1) The personnel responsible for the acceptance of the substation to be inspected control the telemetry and monitoring device to generate remote signaling information;

[0016] (2) Remote signaling information is forwarded by the data communication gateway and then sent to the smart grid dispatching system and the centralized control system respectively;

[0017] (3) The smart grid dispatching system and the centralized control system securely store the received data in their respective databases;

[0018] (4) The main station acceptance personnel run the main station automatic acceptance platform. The main station automatic acceptance platform reads the historical database of the smart grid dispatch system and the historical database of the centralized control system and extracts relevant information for comparison.

[0019] (5) The completed information is compared again with the remote information in the information table management system, and an acceptance report is generated.

[0020] The main station's automatic acceptance platform reads the smart grid dispatch system database and the centralized control system database respectively, and extracts the relevant remote signaling information of the substation to be accepted. The information includes the point number, transmission time, substation name, signal name, action / reset status, and alarm type. The remote signaling information extracted from the smart grid dispatch system database and the centralized control system database is matched according to the point number through the information comparison module. After a successful match, the signal name, action / reset status, alarm type, and information transmission time are compared to see if they are consistent, and whether the information transmission time is within the specified range. This specified time range is determined by the acceptance personnel before the acceptance is carried out.

[0021] For remote signaling information where the point number, signal name, action / reset status, and alarm type are consistent, but the transmission time is outside the specified range, the corresponding modules are used to read the smart grid dispatch system database and the centralized control system database to find the SOE information of the corresponding signal, and the information comparison module is used to compare whether the SOE time is consistent. For signals where the point number, signal name, action / reset status, and alarm type are consistent, and the transmission time is within the specified range or the SOE time is consistent, the information table management module is used to search in the debugging information table of the information table management system according to the substation name and point number, and the signal name and alarm type are compared whether they are consistent. If they are consistent, the signal is considered to have passed the acceptance test.

[0022] Preferably, the data communication gateway verifies the correctness of the remote signaling configuration by directly connecting the station control layer network interface of the data communication gateway to the station control layer network interface of the acceptance device, and directly connecting the remote control channel network interface of the data communication gateway to the remote control channel network interface of the acceptance device, forming a closed loop. By triggering remote signaling signals, a closed-loop test is performed on the real remote signaling, virtual remote signaling, remote signaling composite signal, and telemetry signal, thereby verifying the correctness of the remote signaling configuration.

[0023] Preferably, in step (5), an acceptance report is generated by collecting the acceptance results, acceptance time, acceptance personnel, number of acceptances, and reasons for failure based on the trace data of the acceptance process, and by calculating the acceptance pass rate, acceptance success rate, first acceptance pass rate, acceptance timeliness rate, acceptance time consumption, and personnel capacity. The above information is then formatted and arranged to generate the acceptance report.

[0024] The beneficial effects of this invention are as follows: The substation remote signaling dual-platform synchronous automatic acceptance system and method of this invention can complete the acceptance of remote signaling information from both platforms in one go by comparing the data from the smart grid dispatching system, the centralized control system, and the information table management system. The acceptance report is automatically generated. The acceptance process is accurate, reliable, and fast, which solves the problems of manual acceptance of each item or platform-by-platform acceptance in traditional acceptance methods. It meets the requirements of rapid access of substation remote signaling information to the monitoring platform and realizes the early commissioning of substations. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Definitions:

[0029] SOE information refers to event log information.

[0030] The smart grid dispatching system is a platform used for the acceptance of substation projects.

[0031] The centralized control system is a platform used for substation acceptance testing. Example

[0032] A substation remote signaling dual-platform synchronous automatic acceptance system includes a smart grid dispatching system, a centralized control system, a master station automatic acceptance platform, a data communication gateway, a measurement and control device, and an information table management system. The data communication gateway is connected downward to the measurement and control device and upward to the smart grid dispatching system and the centralized control system, respectively. The databases of the smart grid dispatching system and the centralized control system communicate with the master station acceptance program in real time. The master station automatic acceptance platform also reads the information table management system in real time.

[0033] The monitoring and control device is the object to be accepted. It can be manually controlled to send remote signaling signals and upload them to the data communication gateway. The data communication gateway verifies the correctness of the remote signaling configuration of the data communication gateway and undertakes the functions of remote signaling conversion and transmission. The smart grid dispatching system and centralized control system are necessary platforms for power grid monitoring. The main station automatic acceptance platform includes a smart grid dispatching system database reading module, a centralized control system database reading module, an information table management module, an information comparison module, and an acceptance report module. The smart grid dispatching system database reading module can access the smart grid dispatching system database in real time and obtain data from the database. The centralized control system database reading module can access the centralized control system database in real time and obtain data from the database. The information table management module can access the information table management system in real time and read the commissioning information table information of the substation to be accepted. The main station automatic acceptance platform runs on the server in real time and adopts a B / S structure. The information table management system stores the remote signaling commissioning information table of the substation.

[0034] The working principle of the main station's automatic acceptance platform is as follows: After the signal is transmitted, the corresponding modules read the smart grid dispatch system database and the centralized control system database, and extract the relevant remote signaling information of the substation to be accepted. The information includes the substation number, transmission time, substation name, signal name, action / reset status, and alarm type. The information comparison module matches the remote signaling information extracted from the smart grid dispatch system database and the centralized control system database according to the substation number. After a successful match, the system compares whether the signal name, action / reset status, and alarm type are consistent, and whether the information transmission time is within the specified range. This specified time range is determined by the acceptance personnel before the acceptance process. For remote signaling information where the point number, signal name, action / reset status, and alarm type are consistent, but the transmission time is outside the specified range, the corresponding modules are used to read the smart grid dispatch system database and the centralized control system database to find the SOE information of the corresponding signal, and the information comparison module is used to compare whether the SOE time is consistent. For signals where the point number, signal name, action / reset status, and alarm type are consistent, and the transmission time is within the specified range or the SOE time is consistent, the information table management module is used to search in the debugging information table of the information table management system according to the substation name and point number, and the signal name and alarm type are compared whether they are consistent. If they are consistent, the signal is considered to have passed the acceptance test.

[0035] The information table management module automatically marks signals that have passed acceptance in the information table management system.

[0036] The acceptance report module formats and typeset acceptable signals to generate acceptance reports for acceptance personnel to review and archive; for unacceptable signals, it provides the original information from the historical databases of the smart grid dispatch system and the centralized control system to generate acceptance reports for acceptance personnel to view.

[0037] The main station automatic acceptance platform compares information from the smart grid dispatch system database, the centralized control system database, and the information table management system to achieve synchronous automatic acceptance of substation remote signaling information access to both the smart grid dispatch system and the centralized control system. Example

[0038] A method for synchronous automatic acceptance testing of a substation remote signaling dual-platform system includes the following steps:

[0039] (1) The substation acceptance personnel control the monitoring and control devices 1~n to generate the remote signaling information that needs to be accepted;

[0040] (2) Remote signaling information is forwarded by the data communication gateway and then sent to the smart grid dispatching system and the centralized control system respectively;

[0041] (3) The smart grid dispatching system and the centralized control system securely store the received data in their respective historical databases;

[0042] (4) The main station acceptance personnel run the main station automatic verification platform, the smart grid dispatch system historical data reading module accesses the smart grid dispatch system database, and the centralized control system database reading module accesses the centralized control system database to extract the relevant remote signaling information of the substation to be accepted.

[0043] (5) The information comparison module matches the extracted remote signaling information of the substation to be accepted according to the point number. After successful matching, it compares whether the signal name, action / reset status, alarm type are consistent, and whether the information transmission time is within the specified range.

[0044] (6) For remote signaling information with the same point number, signal name, action / reset status, and alarm type, but whose transmission time is not within the specified range, the corresponding modules are used to read the database of the smart grid dispatching system and the database of the centralized control system to find the SOE information of the corresponding signal, and the information comparison module is used to compare whether the SOE time is consistent.

[0045] (7) For signals with the same point number, signal name, action / reset status, alarm type, and transmission time within the specified range or the same SOE time, search in the debugging information table of the information table management system through the information table management module according to the substation name and point number, and compare whether the signal name and alarm type are consistent. If they are consistent, the signal is accepted; other signals are not accepted.

[0046] (8) The acceptance report module formats and typeset the accepted signals to form an acceptance report for acceptance personnel to review and archive; for unacceptable signals, it provides the original information from the smart grid dispatch system database and the centralized control system database to form an acceptance report for acceptance personnel to view and conduct a second acceptance. Specifically, based on the trace data of the acceptance process, the module collects the acceptance results, acceptance time, acceptance personnel, number of acceptances, and reasons for failure, and calculates the acceptance pass rate, acceptance success rate, first acceptance pass rate, acceptance timeliness rate, acceptance time consumption, and personnel capacity. The module formats and typeset the above information to generate an acceptance report. The acceptance pass rate refers to the final acceptance information pass rate, reflecting the overall project completion status. For example, if 800 out of 1000 acceptance information passes, the acceptance pass rate is 80%. The acceptance success rate refers to the success rate of a single acceptance information, reflecting the efficiency and quality of the acceptance work. If an acceptance information passes the acceptance on the first attempt, the acceptance success rate of that acceptance information is 100%. If an acceptance information passes the acceptance twice, the acceptance success rate of that acceptance information is 50%. First-pass pass rate refers to the percentage of signals that pass inspection on the first attempt; on-time inspection rate refers to the percentage of signals that complete inspection within the specified time; inspection timeout refers to the time taken to pass inspection, reflecting the efficiency and quality of the inspection work. Personnel capacity refers to the workload that staff can handle. Personnel capacity is calculated based on the workload of a particular staff member per unit of time, thus providing a basis for future work arrangements.

[0047] The data communication gateway connects downwards to the measurement and control device and upwards to the smart grid dispatching system and the centralized control system, respectively. The historical databases of the smart grid dispatching system and the centralized control system communicate in real-time with the main station's automatic acceptance platform. The main station's automatic acceptance platform can also read information from the information table management system in real-time. On-site acceptance personnel control the measurement and control device to generate remote signaling information in batches, which is then uploaded to the smart grid dispatching system and the centralized control system via the data communication gateway. The smart grid dispatching system and the centralized control system store the received remote signaling information in their respective historical databases. The main station's automatic acceptance platform reads both historical databases, searches for remote signaling information received at the same time using time logic and SOE information, and compares it with the response information in the information table management system. Based on the comparison results, it automatically determines the correctness of the remote signaling information. Using this method, the correctness of the remote signaling information connected to both platforms can be verified with a single upload, solving the problems of other acceptance methods that either require manual acceptance or two consecutive checks, thus improving acceptance efficiency.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these examples without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
