DFIG型风电场连锁脱网及改善措施分析
摘要：大面积的风电场连锁脱网事故对系统的安全稳定运行带来了严重影响。首先对连锁脱网事故的发生、发展过程进行详细介绍,着重分析了事故的演化机理,指出其核心问题,并基于此提出了改善风电场连锁脱网的控制措施。最后在DIgSILENT/PowerFactory仿真软件上搭建模型,很好地模拟了风电场的连锁脱网事故,并对风电场连锁脱网及其改善措施进行详细比较,旨在对风电场连锁脱网事故进行初步探索和分析。
Abstract:The cascading trip-off events of large-scale wind farms have serious impacts on power systems security and stability. Firstly, the occurrence and development process of cascading trip-off of large-scale wind farms are introduced in detail. Then the evolution mechanism of the events is mainly analyzed, and its key issues are pointed, based on which control measures are proposed to avoid the occurrence of cascading trip-off of wind farms. In the end, the model is built by the DIgSILENT / PowerFactory simulation software, which can simulate cascading trip-off of wind farms very well. In addition, the cascading trip-off case of large-scale wind farms and its improved measure are compared to explore and analyze the cascading trip-off events of wind farms.
