KV变电站设计设计.doc110KV变电站电气部分设计


摘要
本说明书以110kV地区变电站设计为例,论述了电力系统工程中变电站部分电气设计(一次部分),站用电接线设计,短路电流计算,电气设备动、热稳定校验,主要电气设备型号及参数地确定,运行方式分析,防雷及过电压保护装置地设计,电气总平面及配电装置断面设计和无功补偿方案设计,较为详细地完成了电力系统中变电站设计.
限于毕业设计地具体要求和设计时间地限制,本毕业设计只对变电站电气一次部分做了较为详细地理论设计,而对其电气二次部分并没有涉及,这有待于在今后地学****和工作中进行研究.
关键词:变电站短路电流动稳定热稳定

ABSTRACT
The statement about the 110kv transformer area substation design, discussed some electrical transformer substation design (one part) in power systems engineering of the entire process. Through the main transformer stations wiring design, stations wiring design stations, short circuit current calculations, check electrical equipment moving and thermal stability, set the main electrical equipment models and the parameters, the operating mode, design over-voltage protection and mine devices , design general electric graphic and distribution devices flood, and without pensation. Completed substation design in power system,lastly.
Limited to the specific design requirements and design time of constraints, the design only is a part of the electrical transformer stations, and its second part did not involve, which research it in future study and work.
KEY WORDS: Substation, Short circuit currents , Moving stability,Thermal stability
