1、当因故停电，且在较短时间内无法恢复供电时，必须启用备用电源。步骤：
1, when a power failure is due and the power supply can not be resumed in a relatively short time, the standby power supply must be activated. Step:
切除市电供电各断路器(包括配电室控制柜各断路器，双电源切换箱市供电断电器)，拉开双投防倒送开关至自备电源一侧，保持双电源切换箱内自备电供电断路器处于断开状态。
(1) remove the electric circuit breakers (including the circuit breakers of the control cabinet of the distribution room, the power supply of the double power supply switch box), open the double throw anti - down switch to the one side of the power supply, and keep the interrupting state of the circuit breaker in the double power supply switch box.
启动备用电源(柴油发电机组)，待机组运转正常时，顺序闭合发电机空气开关、自备电源控制柜内各断路器。
(2) start the standby power supply (diesel generator set), and when the standby unit runs normally, turn the generator air switch in sequence and provide the circuit breaker in the power control cabinet.
逐个闭合电源切换箱内各备用电源断路器，向各负载送电。
(1) close the standby power circuit breakers in the power switch box one by one, and send the power to each load.
备用电源运行期间，操作值班人员不得离开发电机组，并根据负荷的变化及时调整电压、厂频率等，发现异常及时处理。
During the operation of the standby power supply, the operator on duty must not leave the generator set, and adjust the voltage and plant frequency in time according to the change of the load, and find the abnormal and timely treatment.
