Wind power is one of the common distributed generation in microgrid. According to the requirements of microgrid, permanent magnet synchronous wind generator (PMSWG) for wind energy distributed generation was designed in this paper and it has simple structure, easy control and low cost characteristics, non-controllable rectifier and grid-connected PWM convertor is adopted as the AC grid-connected circuit...
Back to back full-size PWM converter is widely used in direct drive wind power system (DDWPS). It is the most cost-effective converter topology verified in field application. The characteristics of back to back full-size converter of DDWPS based on permanent magnetic synchronous generator (PMSG) are researched on in detail through a precise simulation and an experiment. The control strategy is given...
Since variable-speed generation has a higher energy capturing and converting efficiency than the fixed-speed system, new proposals for wind power system utilize variable-speed generators are introduced, among which permanent-magnet synchronous generator(PMSG) is an attractive choice. This paper describes a sensorless vector control strategy for a direct-driven PMSG, which is connected to the power...
