风力发电系统中的变流器模型简化方法
Simplified method of converter model in wind power generation system
摘要
Abstract
With the increasing shortage of energy, the research on the operation characteristics of wind farm has become a hot topic. Aiming at the disadvantages that the simulation of wind farm is too slow and results in so much memory, the machine side and grid side converters of Double Fed Induction Generator (DFIG) are analyzed. Based on the simplified model of SPWM, under steady state conditions, the concept of switch function is used to replace the model of DFIGˊs machine side and grid side converters with two theory modules, those connected with a DC capacitor. And the output results of these modules will be put back to the rotor of DFIG and the grid for operation. Finally, simulation is carried out on the PSCAD simulation platform to verify the effectiveness of the proposed simplified model.关键词
