摘要
介绍了直驱永磁风电机组基本组成及换流器控制原理,推导了换流器的数学模型,并基于PSCAD/EMTDC软件搭建直驱风电机组风电场的电磁暂态模型,通过系统响应的模拟仿真,分析了直驱永磁风电机组的动态特性以及发生单相接地故障时的暂态特性。
The basic composition and inverter control principle of direct-driven permanent magnet wind turbines are introduced,based on which a mathematical model of inverter is derived,and an electromagnetic transient model of the direct-driven wind turbine wind farm based on PSCAD/EMTDC software is built.Through simulation of system response,the dynamic characteristics of the direct-driven permanent magnet wind turbine and its transient characteristics in case of single-phase ground fault are analyzed.
