本资料为某10KV变电所的继电保护毕业设计

摘要：10KV变电所是将10KV配电电压降为380V的终端变电所，主要为企业和工厂等用户直接供电。本设计是主要针对10KV变电所的继电保护所做的设计，可靠的继电保护系统是变电所安全运行和稳定供电不可或缺的部分，主要用于一次系统的监控、测量和保护。继电保护系统由各种电量与非电量的继电保护仪器相互配合而成。通过提供的原始设计资料进行详细的整定计算确定保护方式、类型和继电保护仪器的整定值，并选择合适的继电器使变电所在故障状态下继电保护系统能可靠、快速、有选择性地切除故障元件或是发出故障信号，从而达到保护仪器和确保电力系统稳定性的目的。并在设计中绘制详细的保护接线原理图和系统展开图。
