异步风力发电机等值及其短路特性研究
Research on Equivalent Aggregation of Asynchronous Wind Power Generators and lts Short-Circuit Characteristics
摘要
Abstract
The short-circuit current supplied by wind farm during the earth fault occurred in fie-line connecting wind farm with power grid is researched, and the main factors influencing short-circuit characteristic of wind power generation set are analyzed theoretically. According to the configuration of wind farm and the wiring of wind power generators, a wind farm is equivalent to several wind power generators, then the equivalent wind speed is calculated by Jensen model, and taking a certain wind farm located in Zhangjiakou for the case, the reasonableness of above-mentioned equivalent method is verified. In allusion to typical operation modes of wind farm and taking PSCAD/EMTDC as the platform, the influences of number of being operate d generators, active power output, fault types and the position where fault occurs on fault characteristic are researched, and simulation results conform to the results from theoretical analysis.关键词
