在2 MW 双馈风电变流器的开发过程中，电磁暂态仿真是验证控制策略和制定相关技术参数的重要手段。建立

了2 MW 双馈风力发电系统电磁暂态仿真模型，介绍了电压空间矢量脉宽调制（SVPWM）技术在PSCAD/EMTDC 的

实现方法，真实反映了变流器的动态开关过程和谐波特性。另对网侧变流器的软件锁相环（SPLL）进行了优化设计，

使之能快速、准确地跟踪电网基波正序电压，有助于改善网侧变流器在电网不对称故障期间的动态控制性能。-2 MW doubly-fed wind power converter development process, the electromagnetic transient simulation is an important means to verify the control strategy and the development of relevant technical parameters. 2 MW doubly-fed wind power generation system electromagnetic transient simulation model in PSCAD/EMTDC achieve a true reflection of the dynamic switching process harmony Potter converter voltage space vector pulse width modulation (SVPWM). Another The the network side converter software, phase-locked loop (SPLL) optimized design, so that can quickly and accurately track the the grid fundamental positive sequence voltage help to improve the network side converter asymmetric fault in the grid during dynamic control performance.
