1) The national survey center and the provincial surveys of each network log in to the national survey OMS (dispatching management system) to prepare their respective plan execution steps;

2) The dispatching management system summarizes the information on the implementation steps of the national survey and the provincial survey plan of each network and conducts a preliminary check;

3) The three-area dispatch management system will generate E-texts from the summarized execution steps of the plan, and send them to the first-area fault collaborative processing system through the small mail service;

4) After receiving the contingency plan E text from the dispatching management system of the third area, the fault collaborative processing system in the first area analyzes, archives, and adds UHV DC fault monitoring information;

5) The fault collaborative processing system in the first area of the national dispatch will generate an E-text of the complete plan, and send it to the fault collaborative processing system of each provincial dispatch through the file transfer service;

6) After receiving the E-text of the national survey, the coordinated processing system of the provincial survey of each network analyzes, archives and displays it.

Specifically, Fig. 4 shows an embodiment of the present invention in which each network provincial survey logs into the national survey OMS system and writes its own plan execution steps. As shown in Fig. The management system OMS establishes its own pre-plan preparation and login users, and the dispatch management system opens its authority. After logging in to the dispatch management system, each user fills in the corresponding pre-plan execution steps according to different UHV DC faults and the actual situation of the regional power grid. When UHV occurs In the event of a DC fault, each region shall operate strictly in accordance with the filled-in execution steps.

2) Figure 5 is a general schematic diagram of the preliminary verification of the information of the provincial dispatching execution steps of the three-area OMS system of an embodiment of the present invention. As shown in Figure 5, the national dispatching management system OMS receives a certain UHV DC related After the fault execution steps in the area, the UHV DC fault plan is summarized on the interface for display, and the dispatcher is notified to check and check. If there is a problem with a certain operation record, the planners of each sub-center notify the corresponding dispatcher to modify it. , until the verification is passed (for example, after the dispatcher checks the verification, he enters the information indicating that the verification is passed) before it can be stored and archived.

3) Figure 6 is a schematic diagram of the three-area OMS system of an embodiment of the present invention generating an E-text from the plan and sending it to the first area through the small mail service. The execution steps of each stage of the plan will generate the corresponding E-text (existing E-text format) according to the fixed format, and the texts will be exchanged between the first and third districts through the small mail service. If the E-text transmission fails, the dispatching management system will be notified to find out the cause of the failure. , until the transfer is successful.

Among them, the smart grid dispatching support system of the National Research Center is partitioned according to security requirements. Different areas run different software, and different areas are isolated by firewalls. Both the first and third areas are in the national investigation.

It is understandable that the transmission failure is judged according to the feedback file, that is, the system will receive feedback after the transmission is successful. If it fails, the notification will be sent until the transmission is successful, and the notification will be sent by the oms of the National Survey Center.

4) Fig. 7 is a schematic diagram of analyzing, archiving, and adding plan monitoring information after receiving the pre-plan E text of the three-zone OMS in one district according to an embodiment of the present invention. As shown in FIG. After dispatching the management system file, read the E file information, store the data in the database, and display it on the man-machine interface. The dispatcher can add the required monitoring data according to each execution step of the UHV DC fault plan, including: fault time The power grid data is recorded once at the time of the fault, and the data is read from the historical database or real-time database through the defined data points (such as the scada data collection point in the smart grid dispatching support system). The historical data is taken from the data 5 minutes before the fault occurs , the real-time data is taken from the time point data of the fault occurrence; during the entire fault processing period, the electronic plan module refreshes the grid data in the fault processing in real time, and reads the data from the historical database or real-time database through the defined data points; The domain event remotely reads the data of the real-time database/historical database of the subordinate dispatching organization, and the data is refreshed in real time during the entire fault processing period. Among them, the remote disposal result data is manually confirmed by the dispatcher of the relevant subordinate dispatching agency, and sent to the State Research Institute.

It is understandable that the data stored in the historical database is permanent, and the real-time database only stores real-time data.

If the zone-1 fault collaborative processing system receives that the plan file of the three-zone dispatch management system already exists, it will update the execution steps of the plan.

Specifically, each plan has a name. If the received plan name is the same as the previous one, the content of the previous plan will be updated; if a new plan name is received, a new plan will be inserted.

5) Figure 8 is a schematic diagram of the E-text generated from the complete plan in the first district of the national survey and sent to each network and provincial survey through the file synchronization service. The text of the fault plan, the file transfer between the National Investigation Center and the provincial inspection center is transmitted through the file transfer service, and the corresponding dispatching organization that transmits the generated complete text of the plan, if the transmission fails, notify the fault collaborative handling system to find the cause of the failure, until The transfer was successful.

6) Fig. 9 is a schematic diagram of parsing, archiving, and displaying after receiving the E-text of the national dispatch by each network provincial dispatcher according to an embodiment of the present invention. As shown in Fig. After the fault plan text, analyze the text information, store the data in the database, and perform real-time display and operation in the first area of the smart grid dispatching support system.

If the fault cooperative processing system in the first area receives the UHV DC fault plan file of the National Commission for UHV DC, it will update the plan information.

During normal full-mode operation, use the peak summer (winter) combined fault handling plan. According to the power grid operation mode, the National Commissioner will revise/confirm the fault plan on a rolling basis for each value. Among them, the dispatcher works in 3 shifts every Value, when each dispatcher goes to work, they will revise and confirm the contingency plan. After the contingency plan is revised/confirmed, it will be shared by the national survey to the relevant sub-centers and provincial surveys to ensure that the latest revised/confirmed contingency plan is uniquely valid.
