发输配全局电力系统分析

提出了发输配全局电力系统分析（简称全局分析）这一新课题，对发输配全局电力系统进行了一体化的分析计算，弥补了传统分析方法中发输电系统和配电系统完全独立进行的局限性。提出了解决全局分析问题的具有普遍性意义的主从分裂法及其收敛性分析理论。研究了全局分析中全局潮流计算和全局状态估计两个重要子问题，理论分析和算例研究均表明，传统的计算方法不再适用于全局分析，而主从分裂法能满足全局分析的要求。

COMPREHENSIVE POWER SYSTEM ANALYSIS INCLUDING TRANSMISSION AND DISTRIBUTION NETWORKS

A new topic of comprehensive power system analysis CPSA including transmission and distribution networks is presented.By the CPSA,the unified comprehensive power system state including transmission and distribution networks can be calculated at the same time,and the limitations of the traditional method,where the transmission network and distribution network are separately considered,are overcome.In order to solve the difficult large- scale problem of CPSA,a new general master- slave- splitting based method with its convergence analysis theory is proposed.Two important sub- problems of CPSA as comprehensive power flow calculation and state estimation are studied.Theoretical analysis and digital tests are carried out and the results show that the new method fits in well for CPSA while the traditional method does not.
