变电站电气总平面布置及配电装置优化

General Layout of Substation Electrical Layout and Optimization of Power Distribution Equipment

在变电站的建设工程中,有效压缩变电站的总体面积是项目建设的核心要求。变电站内含配电装置、变压器、电容器、控制室、自动装置、监控装置、运动通信设施等元件,有些220 kV变电站还是枢纽变电站,且通常会配备无功补偿装置;另外,布置变电站时还需考虑生活、消防供水以及交通道路等条件。变电站电气的总平面布置优化可以参考火力发电厂中的电压配电装置、主变压器等布置方式来考虑。而220 kV以下的变电站在方位布置中存在更多的选择空间。在对变电站电气进行总平面布置时,应以方便出线、减少交叉、主控室采光效果好、能够协调周围环境为目的。变电站在设计工作中,由于其数量多,所以节省空间占地面积很有必要,在具体设计时,需要考虑电压种类、地理位置、出线方向等因素。

In the construction of substations,effectively reducing the overall area of the substation is the core requirement of the project.The substation contains power distribution devices,transformers,capacitors,control rooms,automatic devices,monitoring devices,sports communication facilities and other components.Some 220 kV substations are also pivot substations,and are usually equipped with reactive power compensation devices;in addition,consideration should be given to the layout of the substation Conditions of life,firefighting,water supply,and traffic roads.The overall layout optimization of substation electrical can be considered with reference to the layout of voltage distribution devices and main transformers in thermal power plants.However,substations below 220 kV have more choices in the azimuth layout.When the general layout of the electrical substation is carried out,the purpose should be to facilitate the exit,reduce the crossing,the lighting effect of the main control room is good,and the surrounding environment can be coordinated.In the design work of substations,due to the large number of substations,it is necessary to save space and floor space.In the specific design,factors such as voltage type,geographic location,and outlet direction need to be considered.
