Single Machine Operation of Diesel Generator Set Controller

Nov. 16, 2022

The single operation of diesel generator set is not connected to the grid, the single operation is connected to the grid, the multi unit parallel operation is not connected to the grid, and the multi unit parallel operation is connected to the grid. Under the condition of hardly changing the external wiring, the diesel generator set can be switched between different operation modes. This paper introduces several typical applications of the diesel generator set.

Single machine operation and non grid connection mode of mains power This application mode is the most basic operation mode of EGCP-1, and is also the most widely used occasion at present. In this mode, the precondition for the diesel generator set to operate with load is that the air switch at the mains side must be disconnected.


Determine whether the diesel generator set operates with load through the detection of mains abnormalities or the closing detection of external automatic (AUTO) and running with load switching values. Since the diesel generator set and the mains power are not connected to the grid all the time, there will always be a short time interval when switching the mains power and the diesel generator set supplies power to the load. EGCP-1 software configures this operation mode as follows.


The controller of the load control module is set as the master, and the rest in the automatic (AUTO) state is set as the slave, and the master commands the start and stop of the slave. The master and slave can be set through the panel. The LCD panel on the controller can display their master-slave order. EGCP-1 software configures this operation mode as follows.


The load control mode is not checked ("4-load control mode" in the menu 9 of the common engine, when the external AUTO input point of the EGCP-1 controller is closed, once the mains power is off, the main engine first disconnects the air switch at the mains side, and then all diesel generator sets (the automatic control configuration of the respective EGCP-1 controller operation sequence is effective) are started, and the diesel generator set that reaches the power supply state first closes the corresponding outlet air switch, Other diesel generator sets are automatically synchronized to the grid.


If the load carried by the parallel diesel generator set is lower than the lower limit of the economic load rate, the host will issue a command to order the diesel generator set with the lowest priority to unload and leave the grid and automatically stop; If the load carried by the parallel diesel generator set is higher than the upper limit of the economic load rate during operation, the host will send a command to start the diesel generator set with the highest priority among the diesel generator sets to be paralleled for operation and synchronous grid connection loading.


After the mains power is restored, first order the air switch at the diesel generator set side to trip, then close the air switch at the mains side to automatically shut down the diesel generator set after no-load operation.


The market application prospect of EGCP-1 diesel generator set controller With the gradual opening of the domestic power market, there are many opportunities for the diesel generator set to be connected to the mains. Because of its powerful functions and stable performance indicators, EGCP-1 controller can be applied to emergency standby diesel generator sets, single diesel generator sets in main power stations (grid peak shaving), or several parallel diesel generator sets, There is a lot of application space.
