摘要
在统计2001年辽宁电网责任频率越限情况的基础上,深入分析总结了越限原因,结合理论分析和调度运行实际情况,提出频率调整策略,为调度运行提供指导和建议。2002年实施后,取得了明显的效果,降低了辽宁电网在东北电网频率越限责任中的比率,提高了责任频率合格率,进而提高了电能质量,取得很大经济和社会效益。
Based on statistics of responsibility frequency beyond restriction in Liaoning power grid in 2001, this paper analyzes and summarizes the causes beyond restriction. Combining theoretical analysis and operation dispatching practice, it brings forward the strategies of frequency regulation and control,and provides the guidance and suggestion for operation dispatching as well. After being implemented,the strategies are proved to be effective, such as reducing the ratio of responsibility frequency beyond restriction of Liaoning power grid in Northeast power grid and raising the qualified ratio of responsibility frequency. Consequenlty the quality of electric energy raised,and great economic and social benefit gained.
