基于站域信息共享的低频减载策略

UFLS Scheme Based on Station Area Information Sharing

针对传统低频减载装置存在的问题,提出一种基于站域信息共享的低频减载方案,综合考虑负荷的各种影响因素,利用优序图计算出各种影响因素的权重占比,从而得到每个负荷的加权得分,将其按照从小到大的顺序排序得到低频减载的最优方案。仿真结果表明,相较于传统方案,该方案的频率能够更快地恢复到正常运行范围内,切载能力更加精确。

Considering the problems existing in the traditional under frequency load shedding(UFLS) device, a UFLS scheme based on station area information sharing is proposed. Comprehensively considering various influencing factors of load, the weight proportion of various influencing factors is calculated by using the priority diagram, so as to obtain the weighted score of each load, and sort it in the order from small to large to obtain the optimal scheme of low-frequency load shedding. The simulation results show that compared with the traditional scheme, the frequency of this scheme can return to the normal operation range faster and the load cutting capacity is more accurate.
