摘要
在分析国内外电力系统状态估计研究现状的基础上,结合韶关电网的实际应用情况,阐述了韶关电网状态估计应用软件的功能、网络拓扑分析方法和算法实现等。该软件为山东烟台东方电子信息产业股份有限公司的DF8003系列电力系统高级应用软件的一个模块,采用稀疏矩阵存储方式、基本加权最小二乘算法进行状态估计分析,并以豪斯荷德尔正交变换法来提高状态估计数值的稳定性,同时也克服了程序设计过于复杂、计算速度慢等缺点。
On the basis of having analyzed research status of state estimation in power systems both here and abroad,the paper expounds functions of application software for state estimation of power system,method for network topology analysis and algorithm implementation by combining practical use of the software in Shaoguan power system.The software is a module of DF8006-series advanced application software for power system,it belongs to Yantai Dongfang Electronics Information Industry Co.,Ltd and adopts storage method for sparse matrix,basically weighted least-square method for state estimation analysis.Moreover,it employs HouseHolder＇s orthogonal transformation to enhance stability of state estimation value and surmounts disadvantages such as excessive complexity for program design and low-efficiency calculation.
