摘要
对数字化变电站通信网络性能测试的必要性进行了分析。从数字化变电站的实际出发,参照局域网验收测评规范GB/T 21671-2008,提出了数字化变电站通信网络性能测试的具体项目,并给出了具体的测试方法。介绍了光功率测试和交换机组网后传输时延、丢包率测试两个实际案例,并对测试结果进行了分析。对数字化站网络测试技术进行了展望。
The necessity of communication network testing in digitalized substation is analyzed.By referring to the acceptance test specification for LAN systems GB/T 21671-2008,communication network testing items and testing methods in digital substation are proposed.Two testing examples are given,including optical power testing and the switch latency and frame lost testing.The testing results are analyzed too.At last the prospect of test technology of communication network is analyzed.
