摘要
针对系统实际运行中的电网状态估计存在的问题,结合电网运行特点进行了分析,对提高状态估计准确率的调试方法的改进进行了研究,并提出相应的实用化调试方法,特别是针对环网线路、多回联络线路、超短线路提出了一种估计参数的方法,在实际工作中验证了其有效性,提高了状态估计的准确性,推动了智能电网调度自动化系统D5000在线分析模块应用实用化的发展。
Aiming at the existing problems of power grid state estimation in the actual operation of system, this paper analyzed the characteristics of power grid operation and studied the debugging method which improved the state estimation correct rate, raising the corresponding, actual debugging method. Especially for loop lines, multi-circuit lines, ultra-short lines, a kind of method to estimate parameters was raised to lift the state estimate correctness, which pushes forward the practicality development of D5000 online analy-sis module application in intelligent power grid dispatching automation system.
