摘　　要：继电保护装置的功能是确保电网发生常见的单一故障时稳定运行和正常供电。但保护装置不能很好地感知系统运行状况,因此需要采用安稳控制系统来判断系统运行状况,当升压站送出断面断开时,及时通过安稳装置出口动作于切机;并应根据具体生产情况整定高压电动机低电压定值,确保锅炉的安全灭火和汽轮机的可靠停机。The functions of relay protection equipment are to ensure stable running and normal power supply.But relay protection equipment can’t know the running condition of system,so it needs safety and stability equipment to determine the running condition of system.And it is needed to regulate low-voltage setting of high-voltage motor according to concrete condition in order to ensure safety MFT and turbine trip.
