智能变电站二次回路性能的现场测试与分析

Field test and analysis of the performance of the secondary circuit of the intelligent substation

以丰富智能变电站二次回路性能的现场测试与分析的实践为目的。提出一种通过交换机功能测试和交换机性能测试的实践方案。交换机功能测试方法采用Vlan划分正确性验证、端口镜像功能测试、网络优先级功能测试、网络风暴抑制功能测试、错误帧测试,而交换机性能测试则通过主网性能测试和延时测试实现。以江西某220 kV智能变电站为例进行测试,测试结果均满足性能指标,验证了测试方案的有效性。

The purpose was to enrich the practice of field tst and analysis of the secondary loop performance of intelligent substations.This paper put forward a practical scheme through the function test and performance test of the switch.Among them,VLAN partition correctness verification,port image function test,network priority function test,network storm suppression function test and error frame test were used for switch function test,while switch performance testwas realized through main network performance test and delay test.A 220 kV intelligent substation was taken in Jiangxi Province as an example,the test results meet the performance indicatorsand verified the effectiveness of the test scheme.
