一种基于微扰理论的电厂优化送出在线分析方法
摘要：
本发明介绍了一种基于微扰理论的电厂优化送出的在线安全分析计算方法，包括以下步骤：(1)、配备在线安全分析联合计算系统及全国统一的在线潮流数据；(2)、选取关注的时间断进行初始潮流的计算与记录；(3)、对电厂送出片区的220kV机组进行摄动分析，单一调整该片区各个电厂机组的出力，记录线路输送功率的波动值；(4)、根据关注线路的功率变化量和机组的摄动量，求得该线路对此机组的敏感度；(5)、对关注线路/机组的敏感度进行排序整理，得出影响关注送出线路及关键断面的相关机组敏感度排序和影响程度。
摘要（英）：

The invention provides a perturbation theory-based online analysis method of power plant optimization transmission. The method comprises the following steps of (1) arranging an online security analysis and joint calculation system and nationally unified online power flow data; (2) selecting a concerned time quantum for carrying out calculation and recording of initial power flow; (3) carrying out perturbation analysis on 220kV units in a power plant transmission area, individually adjusting output of the units of a power plant in the area and recording a fluctuation value of transmission power of a line; (4) determining the sensitivities of the line to the units according to the power variation of the concerned line and the perturbations of the units; and (5) sorting and arranging the sensitivities of the concerned line/units and obtaining the sensitivity sort and the influence degrees of relevant units of affecting the concerned transmission line and a critical section.
