摘　　要：谐波状态估计技术是在GPS技术(Global Position System)和PMU技术(Phasor Measurement Unit)基础发展起来的一项新型技术,它通过状态估计手段实现对监测的电网谐波进行分析。系统地介绍了电力系统谐波状态估计技术的概念、谐波测量系统、估计算法和工程应用情况。在介绍状态估计算法时,通过将其分为静态状态估计算法和动态状态估计算法,分别对其进行评述;最后对谐波状态估计技术以后的研究进行了展望。Harmonic state estimation is a newly developed technique based on GPS and PMU, it completes its function of analyzing detected power system harmonics by state estimation. The concepts, harmonic measurement system, estimation algorithm and implementation of harmonic state estimation in electric power system are discussed. The state estimation methods are introduced separately by categorizing as static state estimation and dynamic state estimation. Some problems to be solved for harmonic state estimation in the future are proposed.
