基于报文监听和报文仿真验证GOOSE虚端子连接的不停电检修应用

Application of Maintenance Without Power Outage for Verifying GOOSE Virtual Terminal Connection Based on Message Listening and Message Simulation

对于一次系统不停电的智能变电站扩建、改建间隔装置,需要接收和发送不停电跨间隔装置过程层GOOSE开关量,不停电运行装置不允许改变过程层GOOSE开关量。为解决不停电检修应用的场景需求,同时避免GOOSE组网光纤的插拔,提出一种基于报文监听和报文仿真验证GOOSE虚端子连接的不停电检修应用方法,即在GOOSE报文接收端监听GOOSE发送端报文,改变监听到的GOOSE报文数据集所测试开关量数据的"分"、"合"状态和置位检修品质,然后模拟仿真GOOSE报文发送,最后在接收端通过GOOSE开关量值和检修品质验证GOOSE虚端子连接配置的正确性。

For smart substation expansion and renovation in the condition of primary power system without outage, the bay devices of expansion and renovation must receive and send process layer GOOSE switching value from the device of across multi-bays, and the running device without power outage does not allow changing the process layer GOOSE switching value. In order to solve the scenario requirement of the maintenance application without power outage and at the same time to avoid the plugging and unplugging of the GOOSE networking optical fiber, an application method of maintenance without power outage for verifying GOOSE virtual terminal connection based on message listening and message simulation is proposed, which is to listen message from the GOOSE sending end at the GOOSE message receiving end, and to change the ＂on＂ and ＂oft＂ status of the switching value data which is tested by the monitored GOOSE message data set and the setting maintenance quality. Then GOOSE message sending is simulated. Finally, the validity of the GOOSE virtual terminal connection configuration is verified through GOOSE switching value and maintenance quality at the receiving end.
