基于STATCOM的超级电容储能系统的风电并网

摘要

为了提高电网的电能质量，探讨了一种与永磁同步发电机（PMSG）相连接的电网控制和运行策略。该电机以直驱变速风电机组和静止同步补偿器（STATCOM）为基础，STATCOM的应用是通过风力涡轮机的不脱网运转能力来提高了系统性能，发电机侧变换器的控制策略是应用STATCOM控制器实现传输效率最大化。通过Matlab对其进行了仿真验证。仿真结果表明，带有STATCOM的超级电容器能量存储系统能够提高风能系统电网故障或扰动时的稳态和动态性能。%In order to improve the quality ,this paper discusses a strategy to control and run with permanent magnet synchronous generator(PMSG) connected to the grid. The direct-drive motor with variable speed wind turbines and static synchronous compensator(STATCOM) basis. STATCOM applications through wind turbines do not operate off-grid power to improve system performance. Generator-side converter control strategy is the application of STATCOM controller to maximize transmission efficiency. This paper was carried out by Matlab simulation verification. Super capacitor energy storage system with STATCOM can improve grid wind energy system failures or disturbances during steady-state and dynamic performance.
