摘要
总降变电所及配电系统设计的优劣是变电所得以运行的根本。本设计首先通过负荷计算确定总变电所的变压器的容量、台数,从经济性和可靠性出发确定主接线方式。其次,通过短路计算,参考总降变电所所在地的气象条件和其它有关资料,确定变电所的位置、导线型号及各种电气设备。最后确定相关的保护方案和二次回路方案。在仔细研究各负荷的实际数据,并严格按照国家规定,依照以上设计步骤设计本供电系统设计方案,以到达提高生产效益的目的。

ABSTRACT
The factory power supply system design fit and unfit quality are the bases which the enterprise can move. A set of unreliability, the economical power supply system will be helpful in the enterprise produces highly effective, economical carrying on. First, through the putation then may determine each workshop as well as the main plant transformer capacity, the Taiwan number, embark from the efficiency and the reliability determines the main wiring way. Next, through short-circuits putation, refers to the factory locus the meteorological condition and other pertinent datas, then may determine the transformer substation the position, the wire model and each kind of electrical equipment. Finally determines the related protection plan, for example: Electric cable, transformer relay protection, anti-radar protection and so on. Only then carefully studies the factory the actual data, strictly stipulated according to the country, and only then may design an economy reliable power supply system through the above design procedure, thus arrives the enhancement production benefit the goal。
Key words total drop substation, distribution system, main connection, short-circuits
