农村配电网谐波问题分析与抑制措施探讨

抑制谐波污染、改善供电质量成为农村配电网迫切需要解决的问题。文章简单介绍了谐波的基本性质和造成农网谐波污染的谐波源，分析了谐波污染在电能计量、通信、继电保护、线路损耗等方面可能造成的危害，阐述了谐波源的定位方法及其发展。在此基础上，从受端、主动和被动5方面总结提出了多种谐波抑制的具体措施，为治理农网谐波污染提供较全面的思路与方法。

Analysis on Harmonic Problem and Control Measurements for Rural Distribution Network

To eliminate harmonic and improve power quality is an urgent issue to be resolved in the rural distribution network.The basic characteristic of harmonic are introduced briefly,and some main harmonic sources which caused pollution in rural distribution network are pointed out.In the same time,this paper analyze some potential damage to energy measurement,lines of communication, relay protection and line loss etc.which caused by harmonic pollution.Orientation methods of harmonic source and its progress are also reviewed and discussed.On the basis of these analysis,some idiographic solutions of harmonic are proposed from user side,active and passive aspect.These solutions maybe offer a comprehensive idea and way for harmonic elimination.
