Method and system for determining roles of servers of transformer substation monitoring system

Abstract

The invention relates to a method and a system for determining roles of servers of a transformer substation monitoring system, which are used for solving the role determination problem of double setsof servers of transformer substation monitoring. Key node information interaction is carried out between two servers of a transformer substation monitoring system, the state and the interaction process of a server host are defined, the two parties negotiate to determine main and standby operation roles, and main and standby role determination and real-time dynamic switching are carried out. When the running state of the main server is abnormal in the running process, main and standby switching is carried out, the abnormal server is switched to the standby server, the normal server is switchedto the main server, and monitoring and operation services continue to be provided for an operator station. Through the determination method, the problem of determining the roles of main and standby servers of the transformer substation monitoring system in the dual-computer hot standby operation mode can be effectively solved, and the operation reliability of the transformer substation monitoringsystem is improved.

Description

Technical field[0001]The invention relates to the comprehensive field of computer software technology and power system automation technology, and in particular to a method and system for determining the role of a server in a substation monitoring system.Background technique[0002]The relevant construction technical specifications for substations require that the substation monitoring system and auxiliary control system servers with voltage levels above 110kV adopt a dual configuration, that is, the two servers are used as backups for each other to operate, and the dual-computer redundancy mechanism protects the high availability of the monitoring system application services. In normal operation, one is the primary server and the other is the standby server.[0003]The main server performs SCADA business processing and data distribution in the monitoring system. Each operator station client obtains operating data from the main server for monitoring and control, and the standby server pe...
