根据智能变电站的特点,提出一种针对其二次虚拟回路检测的方案,该方案将根据SCD中的配置信息,通过监测设备之间的通信报文和对设备模拟通信的测试,来验证设备通信行为等运行方面的正确性。该方案充分考虑了智能变电站网络的特点和IEC 61850中规定的通信细节,通过对虚拟回路中需判别的信息进行严格核对,保证了变电站在检测完成后虚拟回路能够满足设计与运行要求,为工程调试以及验收提供了有力的技术支持,也为尽快查找运行中出现的问题提供了便利。
According to the characteristics of intelligent substation, this paper proposes a scheme for secondary virtual loop detection. This scheme verifies the communication of equipment based on the configuration information in SCD by monitoring the communication messages between devices and testing the device analog communication Behavior and other aspects of the correctness of the operation. The scheme takes full account of the characteristics of the intelligent substation network and the communication details specified in IEC 61850. By strictly checking the information to be discriminated in the virtual circuit, the virtual circuit can meet the design and operation requirements after the substation completes the testing. Commissioning and acceptance provided a strong technical support, but also to find the problems in operation as soon as possible to facilitate.
