发电厂保厂用电的措施主要有哪些? | 2012-2-16 16:12:00

发电厂保厂用电的措施主要有哪些?

发电厂保厂用电措施主要有:
(1)发电机出口引出厂高变,作为机组正常运行时本台机组的厂用电源,并可以做其它厂用的备用;作为火电机组,机组不跳闸,即不会失去厂用电;作为水电机组,机组不并网仍可带厂用电运行
(2)装设专用的备用厂高变,即直接从电厂母线接入备用厂用电源,或从三圈变低压侧接入备用电源。母线不停电,厂用电即不会失去
(3)通过外来电源接入厂用电
(4)电厂装设小型发电机(如柴油发电机)提供厂用电;直流部分通过蓄电池供电
(5)为确保厂用电的安全,厂用电部分应设计合理,厂用电应分段供电,并互为备用(可在分段开关上加装备自投装置)
(6)作为系统方面,在系统难以维持时,对小电厂应采取低频解列保厂用电或其它方法解列小机组保证厂用电。
