摘 要电网供电的稳定性与可靠性，对我国的经济发展具有重要的作用。作为既是最清洁又是最丰富的能源之一，现在全世界都在广泛地开发风能。使用风能发电即将成为未来清洁能源的发展趋势。将风能变成电能，这个过程是通过一种叫风电机的设备来实现转换的。接着电能会通过线路汇合流通到变电站，在变电站里电压会被升到可以利用电网来进行传输的高电压，这个完整的一个过程叫做变电对于陆地风电场箱变与升压站的现状，以及主变的选择方案，都进行了详细的分析和研究，确定了主变容量、台数和型号。根据对原始数据的分析，以及设计标准要求，计算出各项电气设备的参数，设计出了最优方案。对系统三相短路电流进行了详尽的计算和分析，根据发电厂的主变容量、运行方式对断路器、隔离开关和互感器进行了详细地选择，对风电场和升压变电站内的电气设备选型给出了详细的选择过程和参数计算，对风电场部分的发电机组、箱式变压器等设备进行了计算和选型，最后绘制出陆地风电场箱变与升压站一次设备设计的电气主接线图。关键词：风电场；风力发电；电气主接线；变压器；短路电流ABSTRACTThe stability and reliability of power grid supply, as a role in China's economic develop. As one of energy sources, wind energy develops around the world widely now. In the future, it’s the trend of use clean energy,for example: wind energy. The conversion of wind energy into electrical energy is accomplished by a device called a wind turbine. Then the electric energy will flow to the substation through the line. In the substation, the voltage will be raised to the high voltage that can be transmitted by the grid. This complete process is called substation.For the status quo of land-based wind farm box change and booster stations, as well as the main transformer selection scheme, detailed analysis and research were carried out to determine the main transformer capacity, number and model. According to the analysis of the original data and the design standard requirements, the parameters of each electrical equipment are calc...
