摘要
通过分析风力发电机系统中过电压的类型、机理、起因、特性以及危害等,论述了风力发电机上存在的多种类型过电压问题,着重研究双馈风力发电机中由变流器进行长缆励磁时产生的过电压,即可再现峰值电压。对开展低压过电压保护基础研究、相关专业标准间的协调等提出了建议。
This paper analyzed the over vohage＇ s types, mechanism, cause, characteristic and damages in wind power generation system. Based on it, the paper expounded a variety of types over voltages existed in wind power generator,in particular the over voltage which is generated in doubly-fed wind power generator by the inverter on long cable excitation. That is the reproduceable peak point voltage. The paper put forward the suggestions for developing the research of low voltage over voltage protection fundamentals and the coordination between relative professional standards.
