Description

technical field [0001] The invention relates to an intelligent substation secondary equipment debugging and analysis system based on network communication in a power system intelligent substation. Background technique [0002] At present, the operation and maintenance management of substation automation system is limited to the configuration management of equipment, or lacks effective and practical automation management methods. The main operation and maintenance still relies on manual methods, resulting in the following defects: 1. Effect defects: existing The industrial computer is a common electrical Ethernet port, which is designed based on the computer motherboard. Although more network ports can be expanded, the smart substation is based on Fast Ethernet communication. The interface requires a fiber-optic Ethernet port, and SV, GOOSE's packet capture debugging has very high requirements for real-time performance, and the time accuracy is required to reach the microseco...

[0002] At present, the operation and maintenance management of substation automation system is limited to the configuration management of equipment, or lacks effective and practical automation management methods. The main operation and maintenance still relies on manual methods, resulting in the following defects: 1. Effect defects: existing The industrial computer is a common electrical Ethernet port, which is designed based on the computer motherboard. Although more network ports can be expanded, the smart substation is based on Fast Ethernet communication. The interface requires a fiber-optic Ethernet port, and SV, GOOSE's packet capture debugging has very high requirements for real-time performance, and the time accuracy requirements reach the microsecond level

2. Technical defects that lead to effect defects: the existing computer motherboards can only be applied to ordinary computing networks. Although the CPU system is multi-tasking, it is not parallel, so its hardware structure and processing mechanism cannot reach real-time performance. requirements, and the number of network ports is too small
