摘　　要：为解决海上风电场内部电气系统过电压问题,运用PSCAD/EMTDC暂态分析软件搭建完整海上风电场模型,并结合海上风电场实际运行工况制定过电压仿真研究方案,对不同过电压事件、断路器位置和合闸角度、故障类型等进行仿真。仿真结果表明,短路故障和甩负荷情况下产生的相对地过电压和相间过电压最大,在海上风电场电气设备选择和设计时应重点考虑这两种情况。In order to solve the problem of overvoltage of the internal electric system of offshore wind farm, PSCAD/EMT-DC transient analysis software was used to build an integrated offshore wind farm modd. Combining actual operating cond-- tions of the offshore wind farm, a research programme for overvoltage simulation was formulated for simulation on different overvoltage events, breaker position, switch angles, fault types, and so on. Simulation results indicate phase-to-ground over-voltage and phase-to-phase overvoltage under conditions of short-circuit fault and load rejection are the largest , which should be mainly considered when selecting and designing electric equipment for the offshore wind farm.
