浅述港口供电系统中谐波的防治

Prevention and Correction for Harmonic Wave of Power Supply System in Port

由于港口供电系统中变压器、整流设备、充气电光源等产生谐波的设备比较多,谐波的产生会对整个供电系统产生不利影响,从而使港口生产面临严重威胁。根据港口供电系统现状,分析谐波产生的原因及谐波对港口供电系统和用电设备的影响,并提出几种防治谐波的方法和设计原则。

There are more devices generating harmonic wave such as transformer, rectifier, gas-filled light source etc. in power supply system of port. The harmonic wave generation will bring out the unfavourable influence on the whole power supply system thus will threaten the port production seriously. Based on the present situation of power supply system of port, the reasons of harmonic wave generation and its influence on the power supply system and electric equipment are analized and the several methods for prevention and correction of harmonic wave and the design principles are proposed.
