摘要
柔性功率调节器(FPC)是一种新型FACTS装置,具有独立的有功和无功调节能力。它利用由双馈电机(DFIG)驱动的大质量飞轮作为储能元件,通过交流励磁控制调节电机输出的有功和无功。由于FPC的转子和电网之间存在双向功率交换,因此输出谐波小的电压源型双PWM变换器是比较理想的交流励磁电源。详细讨论了电压源型PWM整流器的矢量控制策略、调制技术、电路设计以及程序流程,同时进行了FPC用PWM整流器样机的实验。实验结果表明该整流器样机的性能良好,达到了设计要求。
Flexible Power Conditioner (FPC) is a new kind of FACTS equipment which has the ability of adjusting the active and reactive power motor output. The huge flywheel drive by double-fed motor is a storage modulus. By using AC excitation technology the FPC can send out active and reactive power. For double power transmission between the FPC' s rotor and power system, the voltage source double PWM convertor is the most perfect AC field power supply. The vector control, the modulation, the circuit design and the main program of the voltage source double PWM rectifier are all given . And we made a proto type rectifier which is used for FPC, the rectifier has high performance and is close to design standards.
