The development of electric power industry and the level of electrification isa measure of the level of national economic development an important indicator. The design is the subject of power system planning and design ofa specific power system. its performance is directly related to the industrial production and people's lives, and therefore the power system planning and design, must meet three requirements : reliability, flexibility and economy. From the design of the original data analysis began to determine the load capacity and reasonable; Check to meritorious Reactive balance; and the design of the program to do the parison, and then from the parison, make the economy more precise, in order to determine the main wiring system forms the main wiring plant forms; Have the right to determine the form of wiring, power plants, substations capacity models of choice, identified transformers and high voltage circuit breaker models; Finally circuit, and the surge tide, check the selected program, Electrical equipment reliability, flexibility. 目录第一章电力平衡计算一、系统最大供电负荷计算二、工作容量计算 2、1 水电厂工作容量计算 2、2 火电厂工作容量计算三、备用容量的计算 3、1 负荷备用容量 3、2 事故备用容量 3、3 系统需要的备用容量四、系统需要容量计算五、水电利用容量、水电能供给系统容量
