摘要
在Matlab/Simulink中建立了含异步风力机的风电场和STATCOM仿真模型。根据目前风电场接入系统保护配置,针对采用STATCOM后的异步风电场对系统保护配置影响及其存在的问题进行研究。研究表明,加装STATCOM装置可提高风机风电场的低电压穿越能力。提出了合理的改善低电压穿越和继电保护相互配合的措施,尽可能减少风力机脱网,提高电网的安全、稳定性。
This paper established asynchronous wind generators wind farms and STATCOM simulation model in Matlab/Simulink. According to the current wind farms system protection configuration, this paper studied the asynchronous farm with STATCOM device which has effect on protection configuration of system and the existing problems. The research results show that STATCOM device can improve wind farms low voltage ride through （LVRT） ability. This paper put forward the reasonable measures of improving LVRT cooperated with relay protection to minimize the probability of wind power units taking off the grid, improving the safety and reliability of the power grid.
