摘要

根据设计任务书的要求及结合工程实际,本次设计为48MW风电场升压变电站电气部分设计。本期按发电机单台容量2000kW计算，装设风力发电机组24台。每台风力发电机接一台2000kVA升压变压器，将机端690V电压升至35kV 并接入35kV集电线路，经3回35kV架空线路送至风电场110kV升压站。

变电站是电力系统的重要组成部分，它直接影响整个电力系统的安全与经济运行，是联系发电厂和用户的中间环节，起着变换和分配电能的作用。电气主接线是由变压器、断路器、隔离开关、互感器、母线、避雷器等电气设备按一定顺序连接而成的,电气主接线的不同形式，直接影响运行的可靠性、灵活性，并对电气设备的选择、配电装置的布置、继电保护和控制方式的拟定等都有决定性的影响。

本文是小组成员的配合下和老师的指导下完成的，虽然时间很短，没有设计出特别完整的成果，可是我们学会了如何查找对自己有用的资料，如何设计一个完整的风电场电气系统。并且我们设计出了三张图，包括风机与箱式变电站接线图、35KV风电场集电线路接线图、110KV变电所电气主接线图,在这里感谢小组成员们的辛勤付出和贾老师的耐心指导。

Abstract

According to the requirements of the design task and combined with the engineering practice, the design is part of the 48MW wind power booster substation electrical design. This period in accordance with the generator unit capacity of 2000kW calculation, installation of 24 wind turbine units. Each wind generator with a 2000kV A step-up transformer, the terminal 690V voltage to 35kV and access 35kV integrated circuit, the 3 35kV overhead transmission line to the wind farm 110kV booster station.

Substation is an important part of power system, which directly affects the safety and economic operation of the whole power system, is the intermediate link between power plants and users, plays a role in transformation and distribution of electricity. The main electrical wiring is composed of a transformer, circuit breaker, isolating switch, transformer, bus, surge arresters and other electrical equipment according to a certain order which is formed by the connection of different form, the main electrical wiring, directly affect the operation reliability,flexibility, and the choice of electrical equipment, power distribution equipment arrangement, relay protection and control to have a decisive impact.

This paper is combined with team members and under the guidance of teachers completed, although time is very short, no design particularly integrity achievements, but we learned how to find useful on its own data, how to design a complete wind farm electrical system. And we designed the three pictures, including fans and box type substation wiring diagram, 35KV wind farm set wiring diagram of an electric circuit, 110KV substation main electrical wiring diagram.Thanks to the team members to work hard and Jia teacher's patient instructions here.
