基于FIR-MSMA的配电网测频算法
摘要:针对配电网中含有谐波、带外干扰及其他严重干扰的同步相量测量问题，提出一种基于有限冲击响应滤波器和M类同步相量测量算法(finite impulse response-M synchrophasor measurement algorithm, FIR-MSMA)相结合的配电网测频算法。该方法利用最小二乘法设计出FIR-1滤波器提取低频信号，在此基础上利用设计的FIR-2滤波器实现频率测量的目的，并分析2种滤波器参数设定的原则。利用Matlab软件编制算法仿真程序，验证所提算法的动态测量性能。结果表明，相比于基于离散傅里叶变换的算法和基于滑动平均滤波器的算法，基于FIR-MSMA的算法具有更强的抗干扰能力和更高的测量精度。
Abstract：Aiming at the problem of synchrophasor measurement with harmonics, out-of-band interference, and other dynamic interferences, a new frequency measurement algorithm combining a finite impulse response filter with M-class synchrophasor measurement algorithm (FIR-MSMA) is proposed for distribution networks. Firstly, the least squares method is utilized to design a FIR-1 filter for extracting the low-frequency signals, and to design a FIR-2 filter for measuring frequency. Then, the parameter setting principles for two types of filters are analyzed. Finally, simulation examples in Matlab software are performed to verify the dynamic measurement performance of the proposed algorithm. The results show that the FIR-MSMA algorithm has stronger anti-interference ability and higher measurement accuracy than the discrete Fourier transform algorithm and the sliding average filter algorithm.
