电气主结线的布尔代数表达式与运行方式的分析

THE BOOLEAN ALGEBRA EXPRESSION OF THE ELECTRICAL FIRST CIRCUIT AND ANALYSIS OF THE OPERATIONAL FORMS

本文对电气主结线的布尔代数表达式,结合供电系统实际运行的基本技术要求,进行了全面的分析.并举例阐明不同形式的电气主结线,其布尔代数表达式的诸项不一定均能满足供电系统运行的基本技术要求,应对电气主结线的布尔代数式诸项进行检查,删去无实际运行意义的各项,最后确定具有实际意义的运行方式,作为评估电气主结线可靠性和灵活性的依据,则更符合电力系统的运行实际.

In the light of the basical technical requirements of the practical operation ni the power system, this paper analyzes the Boolean algebra expression of the electrical first circuit in an all-round way, and gives some examples to state that not all the terms of Boolean algebra expressions of different electrical first circuits satisfy the basical technical requirements.This paper,therefore,checks up all the terms of the Boolean algebra expression of the electical first circuit and deletes the redundant terms so as to determine the real operational forms which have practical operational significance. As the basis for appraising the reliability and flexibility of the electrical first circuit, it is more accordant with the actual conditions of the power system operation.
