OPEN3000 system platform application function supports multi-server hot backup, cold backup self-starting, data synchronous replication and "1+N" safe function for data preservation in case of complete failure; the intelligent modeling tool is at the international leading level; the PAS function enables predictive analysis , Judgment and processing are more rapid and accurate; AVC function will effectively reduce line reactive power transmission, reduce power grid loss, and finally realize closed-loop operation of optimal control of reactive power and voltage in the entire network; accurately and timely provide dispatchers with real-time information of the power grid, remote signal displacement, The action of accident push screen is accurate; software such as stable section monitoring provides a strong guarantee for dispatchers to deal with accidents in a timely manner; the function of accident recall (PDR) provides a credible basis for dispatching and operation professionals to analyze the cause of accidents after the event. On the basis of meeting the dispatching needs to the greatest extent, it is also fully considered to provide dispatchers with the most concise and clear information, so functions such as division of responsibility areas, authority management, and information hierarchy are added to the system, which is the implementation of the "three sets and five majors" The carrier of important deployment not only improves the safety factor of the power grid, but also lays a solid foundation for the integration of regulation and control, and the integration of prefectures and counties.

In accordance with the requirements of the State Grid Corporation's "three sets and five majors" system, the company has established a "big operation" production model based on the integration of prefectures and counties and the integration of regulation. As a smart grid dispatching technical support system, the dispatching automation system plays a pivotal role in the "big operation" production system. At the same time, the refined management of various majors in the large-scale operation puts forward higher requirements for the operation and maintenance of the dispatch automation system.

With the large-scale commissioning of integrated automation substations, the substations have achieved no one or few people on duty, and the monitoring team located in the control center is responsible for monitoring the real-time information of the substations under its jurisdiction. In order to ensure the safe and stable operation of the power grid, according to the dispatching requirements of the superior, it is necessary to classify and set the information of the substation access dispatching automation system (1. Accident signal type A; 2. Abnormal signal type B; 3. Telemetry limit signal type C; 4. Substation bit signal class D; 5, notification signal class E). Due to the huge amount of information in the integrated automation substation, the relevant information parameters are manually input in the database at present, which takes a long time for maintenance and low work efficiency; at the same time, due to the large amount of data, the accuracy of information setting is difficult to guarantee.

At present, there is no good way to batch and quickly process information classification using manual input. After the project is completed, according to the current conventional 220kV substation, there are 1,500 pieces of information that need to be classified and set. At this stage, manual input takes 2 to 3 working days (about 20 hours) to complete, and the work efficiency is low.

Detailed ways

As shown in Figure 1, the dispatching automation system accesses the real-time information of regional integrated automation substations. The information accessed should meet the needs of monitoring and operation under the large-scale operation system. Operation and maintenance personnel, the automatic operation and maintenance personnel are responsible for the entry and maintenance of the database system. The OPEN3000 system database system currently in use adopts the ORACLE commercial library, converts EXCEL tables into data files suitable for the OPEN3000 system database, uploads them to the data server of the dispatching automation system through FTP, and can be directly called by the OPEN3000 system database. The specific workflow is as follows:

Organize and check substation monitoring information classification table;

Save the substation monitoring information classification table as a text file;

Copy the text file to dispatch automation system engineer workstation;

Invoke the compiler program at the dispatching automation system engineer workstation to generate the OPEN3000 system database file;

Upload the generated OPEN3000 system database file to the scheduling automation system server through FTP.

Wherein, the dispatching automation system is a dispatching automation system commonly used in power control centers, and the substation automation system is a substation comprehensive automation system commonly used at present.

As shown in Figure 2, the research and development of the content of the substation monitoring information classification automatic processing project is based on the current application program of the OPEN3000 system. The high-level language interface software compiles and processes the substation access scheduling automation system information table, and generates files that meet the OPEN3000 system database (ORACLE database). Generate files that meet the requirements of OPEN3000 system database (ORACLE database), and import them into the data server of the scheduling automation system through FTP to perform batch information classification settings. The compiler is written in C or C++ language, and SQL statements and procedures can be embedded in C\C++ and other main languages. (PL/SQL) statement to manipulate the data in the database. The main workload in the early stage is to conduct in-depth and detailed research on multiple OPEND3000 system databases, and analyze their physical and logical structures. Through research and analysis of multiple OPEND3000 system databases physically stored in the network, logically it can be regarded as a single big database. Simultaneously access the data in remote databases through the network, and establish an access mechanism through database links (DB-LINKS) between multiple OPEND3000 system databases connected by the network, which is equivalent to the remote login of a user of the other party. operate. However, the advanced management methods adopted by the system, such as synonyms (SYNONME), make us unaware of this process, as if the remote data is in the local. Database replication technologies include: real-time replication, scheduled replication, and store-and-forward replication. In terms of the intensity of replication, there is replication of the entire database table, and replication of some rows in the table. During the replication process, there are means of automatic conflict detection and resolution.

By applying this program, the work efficiency of automated operation and maintenance personnel can be greatly improved. According to the current conventional 220kV substation, there are 1,500 pieces of information that need to be classified and set. At this stage, manual input takes 2 to 3 working days (about 20 hours) to complete. It can be completed in about 2 hours by using the substation monitoring information classification program, which saves 80% of the working time and greatly improves the work efficiency. At the same time, it can effectively ensure the accuracy of information classification settings and ensure the reliable operation of the smart grid dispatching technical support system. It provides strong technical support for the integrated operation of regulation and control under the "big operation" system.
