摘要

工频同步相量是支撑电力系统分析、保护和稳定控制的基本信息，不同场景对其估计精度与速度要求日益严格。短路故障初期，工频分量、衰减直流分量(decaying DC component

DDC)以及谐波之间频域混叠，导致工频相量准确估计面临严峻挑战。针对多种干扰影响相量测量精度问题，提出一种基于改进离散傅里叶变换的强鲁棒性相量估计算法。首先，对DDC误差原理进行分析，利用多个1/4波离散傅里叶变换(discrete Fourier transform

DFT)计算频域误差，同时引入放大乘子以提升算法鲁棒性；然后，在改进DFT基础上提出算法计算量精简方法，将算法计算效率提升近一倍；最后，构建二次谐波陷波滤波器配合所提算法，弥补了二次谐波难以滤除的缺陷。算例测试表明，所提算法不受DDC参数与采样频率限制，并在多种干扰下表现出良好的抗干扰能力，同时有效缩短了相量估计的暂态时间。
