The improved measure to enhance stability of the stable controlling equipmentof 500 kV Yandu substation;

提高500kV砚都站安稳装置安全性的改进措施

But relay protection equipment can’t know the running condition of system,so it needs safety and stabilityequipment to determine the running condition of system.

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。
