摘要
电力系统的谐波由于受随机性、分布性、非平稳性等因素影响,常规的谐波检测方法在实际运用中均有不同程度局限。针对这一问题,在常规方法基础上的拓展和改进方法应运而生。本文对近年来电力系统谐波检测的新方法进行了分析和评述,并展望了电力系统谐波检测方法的发展趋势。
It is very difficult to carry on accurate detection to harmonic in the power system because of its randomicity, distribution and non-stability. It has been a constant effort for researchers to explore more effective detecting and realization methods. Therefore new methods emerge as the times require on the expansion and improvement of the conventional method. The paper analysis and review some novel methods appeared in recent harmonic detecting area, and predict the development tendency of harmonic detecting in the electric system.
