| 摘 要： | 从经济原因考虑,目前典型设计两台机组的电厂,多只设计一台启备变供给两台机组启备厂用电源。当该电源因故障或检修等原因无法保证时,两台机组均将失去启备电源,对于机组的安全运行将带来影响;同时,机组停机后将无法再启动,失去发电能力。本方案在保持原6 kV厂用电源系统结构的情况下,使两台机组能互相提供厂用电源,从而克服上述设计缺陷,增加了厂用电源供给的可靠性。

| Abstract: | Due to the economical consideration,in the current typical design of power plant with two units,only one start and stand-by auxiliary transformer was mostly designed for the two units as start and stand-by auxiliary power supply.When the power supply is failure or in overhaul,the two units will operate without start and stand-by power supply,their operation security will be impacted;and if the unit shutdown,it could not restart and could not generate the electricity.A reformation scheme was introduced in th... |
