1、 摘 要 我国风能资源丰富，在能源极度紧缺的今天，风力发电不但是解决我国能源和电 力供应短缺最现实的战略选择，也是改善和优化电力能源结构的要求。同时，开发和 使用风力发电这种清洁可再生能源，也是保护大气环境、改善生态环境的迫切需要， 符合二十一世纪人与自然和谐可持续发展战略的目标要求。 本设计根据设计要求及结合工程实际需要， 以现实中投产的 49.5MW 风电场为原 型，对电气系统进行整体设计。主要包括风电机组的选型和整体布局，箱式变电站的 选型，220KV 升压站的设计以及电气设备的选型，其中涵盖升压站主接线、短路电 流计算、电气二次设备选型、电气二次设备配置、升压变电站整体布局、无功补偿、

2、 监控系统配置等方面。设计完成后的风电场将会成为电力系统的一个重要的组成部 分，为社会输送清洁的电能。 关键词：风力发电机组 电气设备 无功补偿 电力系统 Abstract Wind energy resources are rich in our country, in todays extreme shortage of energy, wind power is not only to solve the energy and power supply shortage in Chinas strategic choice, is to improve and optimize the

3、structure of electric energy requirements.Wind power at the same time, the development and use of this kind of clean and renewable energy, and protect the atmospheric environment, improve the ecological environment is an urgent need to conform to the 21st century the human and the nature harmonious

4、and sustainable development strategy goals and objectives. This design according to the design requirements and to meet the needs of practical engineering, production of 49.5 MW wind farm in reality as the prototype, the overall design was carried out on the electrical system. Mainly includes the se

5、lection of wind turbines and the overall layout, selection of box-type substation, the design of 220 KV booster stations and electrical equipment selection, which covers the main booster station wiring, short-circuit current calculation, electrical equipment selection, electrical equipment, step-up

6、substation general layout, the reactive power compensation, monitoring and control system configuration, etc. After the completion of the design of wind farm will become an important part of power system, conveying clean electricity for the society.
