PLC Application in Generator Set Automatic Control System

Diesel generator sets as a spare power supply, widely used in all walks of life such as defense, oil, transportation, and mines. The PLC automation control system is used in hospitals, real estate, banks, hotels and other industries.

1, diesel generator setAutomation functionIt can realize the emergency start of the main supply of the main power supply, and the main supply of the main supply is automatically stopped.

2. The unit sets the PLC startup program to prepare the unit, and the unit is interrupted from the city to the unit startup, and the main switch is powered to the load, and the entire process can be completed within 20s.

The specific work process is as follows: When the mainstream interrupt 2S, the diesel generator set motor is started, and the unit began to run. Under the conditions satisfied in the voltage and speed, the unit automatically connects to the load; when the main electric power supply is 5s, the diesel generator set automatically stops and stops the power supply.

3. When the diesel generator set, if the oil temperature is too high, the PLC can achieve sound and light alarm; if the oil pressure is low, the speed, the PLC can control unit emergency stop, and sound an audible alarm signal; if it takes overcurrent Automatically disconnect the main switch while emitting a sound and light alarm signal.

The working environment of the diesel generator is generally a bad, like the high temperature and alkritine is not suitable for the long-term residence of the operator, and the PLC can automatically start and stop without the unmanned operation of the unit. Therefore, the PLC can improve the anti-interference ability of its control system, and it is also convenient for customers to use and maintain.
