摘要:
双馈风力发电机的转子由电压源PMM 逆变器供电,因轴承电流导致轴承损坏的现象非常普遍。本文通过分析共模电压的产生机理,提出了双馈风力发电机的高频等效电路模型,分析了各种类型的轴承电流及其流通路径,同时总结了抑制轴承电流的主要措施及基本设计原则。
Abstract:
As the rotor of doubly-fed induction generator (DFIG) for wind power is supplied by PWM voltage source inverter, bearing damage caused by bearing current is very common.Through analyzing the generation mechanism of common mode voltage, it presented a high frequency equivalent circuit model of DFIG,analyzed the characteristics of various bearing currents and their flow paths,and summarized their preventive measures and basic design principles.
