An optimal generator tripping method for emergency monitoring and control devices in new energy stations

新能源场站全景监控系统的新能源精益控制功能由紧急态监控装置来实现。紧急态监控装置的精细化切机可有效避免直接切除汇集线或升压变压器导致的过电压等次生问题。由于新能源场站的发电单元数量众多,在切机过程中使用穷举法查找最优组合不可行,需要对切机策略进行优化。本文提出一种新能源场站紧急态监控装置的最优化切机算法,可有效提高计算效率,快速找出最优切机组合,保证紧急态监控装置快速响应稳控装置的命令。

The new energy lean control function of the panoramic monitoring and control system for new energy stations is achieved by emergency monitoring and control devices.Precision generator tripping of emergency monitoring and control devices can effectively avoid secondary problems such as overvoltage caused by direct cutting of collection lines or transformer.Due to the large number of power generation units in new energy stations,it is not feasible to use exhaustive method to find the optimal combination during the execution of generator tripping,and it is necessary to optimize the tripping strategy.An optimal generator tripping method for emergency monitoring and control devices in new energy stations is presented,which can effectively improve computational efficiency,quickly find the optimal tripping combination and ensure that emergency monitoring and control devices can quickly respond to commands from stability control devices.
