35KV电网继电保护设计(附任务书,说明书和计算书)

摘 要 随着我国电力工业的迅速发展，各大电力系统的容量和电网区域不断扩大。继电保护装置广泛应用于电力系统、农网和小型发电系统，是电网及电气设备安全可靠运行的保证。本设计根据典型的35kV发电厂和变电所电气主接线图，根据厂、所继电保护、自动装置、励磁装置、同期装置及测量表计的要求，配置相应的电流互感器及电压互感器，并选择出相应的电流互感器及电压互感器的型号和变比、编制不同的电力系统运行方式、确定变压器中性点接地位置和台数、进行短路电流计算、对发电机、变压器、线路、母线的继电保护的整定计算、配置系统保护配置图。 关键词： 电气设计、继电保护，保护装置 Abstract In recent years, with the development of power industrial, the capacity of power system and the area of the electricity network are constantly extended. The relay protector is aboard applied in power system, rural electricity network and generate electricity system, which assure the electricity network and electric equipment running on the safe side. The graduate’s design depends on the ma in wiring diagram of 35 kilo-volt grade. According to protection relay, automatic control equipment, excitation equipment, power station, power plant this request, Keywords: Electrical design, protection relay, protection equipment
