摘　　要：针对大规模风电场汇集并网后引起的电压稳定性问题,研究了适用于大容量风电汇集系统的电气主接线方案。在此基础上,以新疆地区电网为案例,分析辐射形、链形和混合形三种典型拓扑结构对电压稳定性的不同影响。仿真结果表明,通过改变风电接入后的电网拓扑结构,能够提高并网点静态稳定裕度,同时缩短故障后电网暂态响应时间。For the voltage stability problem with the interconnection of large-scale wind power centralized system,different main electrical wiring cases which are suit for large capacity wind power are studied.In additional,taking Xinjiang grid as a study example,the impacts of different typical topologies of wind power system such as chain,hybrid and radiate shape on voltage stability are researched.The results show that a better typical topology can improve the static voltage stability of wind power grid,and at the meanwhile,can shorten the transient response time of wind power after faults.
