摘要(Abstract)：

应用于配电网的同步相量测量单元(phasor measurementunit,PMU),面临更恶劣的测量环境和更高测量精度双重压力,已有的PMU装置未能满足配电网测量高精度和快速响应要求。为实现配电网测量目标,PMU研制的核心是与配电网环境相适应的高性能测量算法。应用PMU最优滤波原理设计出针对配电网的PMU测量算法,并基于NI Compact-RIO 9036平台搭建了PMU功能样机,由现场可编程门阵列(field programmable gate array,FPGA)实现该测量算法。为检验测量算法实际性能,根据配电网测量要求,在样机平台上由FPGA生成测试信号源,形成配电网PMU性能自评估系统。通过对样机系统在静态、动态、暂态、强谐波和噪声条件下测试结果进行分析,验证了该测量方案的高精度和快速响应能力,证明了其优异的实际测量性能,展示了其重要的应用价值。
