电力系统在线安全分析与预警系统实用化研究

Research on practical algorithm of power system on-line security analysis and early warning system

针对在线安全分析及预警系统部分结果无法达到指导在线运行要求的问题,提出了暂态稳定曲线在线分析、小干扰稳定振荡模式在线辨识、电压稳定薄弱点在线辨识、危险断面在线搜索的实用化算法。实际系统应用结果表明,该算法取得了良好的效果,能够在线为电网调度运行人员提供决策依据。

Aiming at the problem that some results of power system on-line security analysis and early warning system can not meet the requirements of guiding on-line operation,a practical algorithm is proposed for on-line analysis of transient stability curve,on-line identification of small signal stability oscillation mode,on-line identification of weak points of voltage stability and on-line search of dangerous cross-section.The actual system application results show that the algorithm has achieved good results and can provide on-line decision-making basis for power network dispatching operators.
