发电厂变电所主接线方案的模糊综合评判

Fuzzy Comprehensive Criterion of the Main Wiring Scheme of Power Plants and Substations

对发电厂变电所的电气主接线方案进行比较时，普遍采用的是在保证可靠性的前提下，作技术经济比较。这种方法与设计人员的论述、经验、习惯有关缺乏客观性。本文采用模糊决策的理论和方法建立数学模型，对电气主接线方案进行模糊综合评判，可作为设计人员在进行主接线方案选择时的依据。

The common mathod used in comparing the main wiring scheme of power plants and substations is to make technic and economic comparison under a promise of ensuring essential reliability.Relating to the experience and tradition of designers,this method is lacking in objectivity.Using the fuzzy decision theorem and mathod,the math model of the main wiring of power plants and substation has been developed in this paper.A mathod to make the fuzzy comprehensive criterion of the electrial main wiring scheme is presented.This mathod can be used by designers in selecting the main wiring scheme.
