What is the reason for the reverse power transmission of diesel generator set?
2021-06-25
Each diesel generator set will be equipped with a load output switch. Before starting the diesel generator set, the load switch must be disconnected. Only when there is no current on the grid after the power failure, can the current of the generator set be transmitted to the grid. At this time, we must ensure that the grid switch is off, otherwise, when the power supply is restored, it is easy to turn back the power supply. The situation of self provided diesel generator transmitting power to the city grid is called reverse transmission. There are two serious consequences
1. If the power supply of the city power grid is not cut off, the power supply of the city power grid and the power supply of the self provided generator set will be connected at the same time, which will destroy the generator set. If the capacity of self provided generator set is large, it will make the market network vibrate.

2. The city power grid has been cut off and is being overhauled. If the self provided generator sets are reversed, the overhauling personnel of the power supply department will get electric shock.
