Diesel generator sets are classified according to control methods

Diesel generatorsIf groups are divided according to control methods, they can be mainly divided into the following three types:

1. Manual unit: This type of diesel generator set is more common. The unit has the function of automatic adjustment of voltage and speed. The operator can start, close, open and shut down the unit in the machine room. This type of diesel generator set is usually used as a Main power or backup power.

2. Self-starting unit: The self-starting diesel generator set is based on the manual unit and adds an automatic control system. When the mains power suddenly fails, the unit has automatic starting, automatic voltage regulation, automatic frequency modulation, automatic switch switching and automatic Shutdown and other functions; when the oil pressure of the unit is too low, the oil temperature and cooling water temperature are too high, it can automatically send out audible and visual alarm signals; when the unit overspeeds, it can automatically shut down in emergency to protect the unit. The advantage of the self-starting diesel generator set is that it greatly reduces It reduces dependence on operators and shortens the time between mains power outage and power supply from the unit. This type of unit is usually used as a backup power supply.

3. Microcomputer controlled automation unit: This diesel generator unit is composed of a diesel engine with perfect performance, a synchronous generator, an automatic fuel (oil, cooling water) compensation device and an automatic control panel. The automatic control panel is controlled by a programmable automatic controller. In addition to the various functions of the self-starting unit, it can also automatically increase or decrease the unit according to the load, automatically handle faults, automatically record and print unit operation reports and fault conditions, and implement comprehensive automatic control of the diesel generator set. It is realized by the serial communication interface The central station performs real-time remote control, remote signaling and telemetry for units scattered throughout the place, thereby achieving unattended operation. The degree of automation of the unit can be configured according to actual needs. This type of diesel generator unit is particularly suitable for use as an emergency power supply.
