在未来的电网代码中，风电场将必须满足苛刻的故障穿越要求。在电网的几种故障中，电压暴涨是一个关键事件。如果没有额外的故障缓解设备，配备双馈感应发电机的风力发电场将无法满足新的电网规范要求。本文对动态电压恢复器和静态同步补偿器在不改变相角的情况下抑制风电机组三相电压隆起的适用性进行了研究和比较。缓解设备为风能系统增加了缺失的高压穿越能力，以便与电网兼容。给出了系统的功能、控制结构、设计和性能，并进行了仿真验证。
In future grid codes wind farms will have to fulfill demanding fault ride through requirements. Among several grid faults the voltage swell is a critical event. Wind farms with doubly-fed induction generators will not be able to fulfill the new grid code requirements without additional fault mitigation equipment. In this publication the applicability of the Dynamic Voltage Restorer and the Static Synchronous Compensator to mitigate a three phase voltage swell without phase angle variation at a wind turbine is investigated and compared. The mitigation equipment adds the missing high voltage ride through capability to the wind energy system in order to become grid compliant. The function, control structure and design and the performance is presented and verified by simulations.
