| Abstract: | The transmission line of the 2 units was a single circuit, and standby supply was using foreign power in Shenhua Shendong Power Co.,Ltd., Salaqi Power Plant. Through the alteration of power supply for station on the 6 kV system, realized the dual units mutual backup, while single unit operation of the power plant, the station service supply power could be provided by the operation unit, do not need to purchase power basically, enhance the operation reliability of power plant, and the economy of the units. |
