DFIG风电场短路电流计算影响因素分析
Analysis for influence factors on short-circuit current calculation of DFIG wind farm
摘要
Abstract
With the increasing capacity of wind farms, the analysis of short circuit current of wind farms is becoming more and more important.The doubly fed induction generator (DFIG)is widely used in the domestic wind farms that have been put into operation in China. Studying the short-circuit current characteristics of the DFIG wind farm is of great significance to the calculation of short-circuit current and the analysis of restrictive measures in the power grid. In order to analyze the influence factors of the short-circuit current characteristic of the DFIG wind farm, the short-circuit current calculation model of the DFIG wind farm is set up firstly. Then the factors that may affect the short-circuit current of the DFIG wind farm are analyzed based on the model. At last, a DFIG wind farm interconnected grid is established on the DIgSILENT platform. The influence of wind speed,fault type,fault location,collector impedance,Crowbar resistance and control method on the short-circuit current of the DFIG wind farm is simulated and analyzed, which provides a reference for the further study of the short-circuit current characteristics of the DFIG wind farm.关键词
