main electrical scheme

Capable of calculating the adequacy, security and economics indices of the main electrical scheme of a station based on the general n+ 2 State Markov Model, the software has realized the sensitivity analysis of reliability parameters.

该系统基于统一n+2状态Markov模型，可对电站电气主接线的充裕性指标、安全性指标和经济性指标进行计算，并能实现系统可靠性指标对元件可靠性参数的敏感度分析。

The main electrical scheme of a station is principal part of power system electrical connection, and its structure not only determines whether customers can acquire enough electric energy, but also influence economical efficiency of construction and reconstruction of a station.

电站主接线是电力系统接线的主要部分，其结构不仅决定用户能否获得足够的电能，而且也影响到电站建设和改造的经济性。

According to the demand of no-man substation, this paper suggests that the design should consider the power system, simplify the main electrical scheme, dispose relevant safeguarding system to the structure of power network.

根据无人值班变电站要求，提出110kV市区变电站应从电力系统整体出发，力求电气主接线简化，配置与电网结构相应的保护系统。
