Classification of Diesel Generators According to Control and Operation Methods

Diesel generator sets can automatically start power generation at any time, operate reliably, ensure the voltage and frequency of power supply, and meet the requirements of electromechanical equipment. With the recent tightening of power restriction policies, diesel generator sets will be more widely used in communications, mining, and In airports, factories and other departments, there are many types of diesel generator sets. Basically, they can be divided into field-operated generator sets, compartment-operated generator sets and automated generator sets according to the control and operation methods.

1. Operate the diesel generator set on site. Unit operators perform routine operations such as starting, closing, speed regulation, opening, and shutdown of the diesel generator set in the engine room. The vibration, noise, oil mist, and exhaust gas generated by this type of generator set during operation will cause certain adverse effects on the body of the operator.

2. Diesel generator set is operated in the compartment. The engine room and control room of this type of diesel generator set are set up separately. In the control room, the operator starts, regulates, and stops the diesel generator set in the engine room, monitors the operating parameters of the unit, and monitors the engine room Auxiliary machines are also centrally controlled. The compartment operation can effectively improve the working environment of the operator and reduce the damage to the health.

3. Automated diesel generator set. After many years of research by relevant units, the automation of diesel generator sets can now be unattended, including self-starting, automatic voltage regulation, automatic frequency regulation, load regulation, automatic paralleling, automatic increase or decrease of units according to load size, and automatic processing. Failure, automatic recording of printer group running reports and failure conditions.The automatic generator set can automatically start 10~15s after the mains is interrupted, instead of the mains for power supply, the degree of automation can be set according to actual needs.

According to the classification of automation functions, diesel generator sets can be divided into basic diesel generator sets, automatic start diesel generator sets and microcomputer automatic control diesel generator sets.

1. The basic diesel generator set is relatively common, with automatic voltage and speed adjustment functions, and can generally be used as the main power supply or backup power supply. It is composed of diesel engine, enclosed water tank, fuel tank, muffler, synchronous alternator, excitation voltage adjustment It is composed of device, control box (screen), coupling and chassis.

2. The automatic start diesel generator set adds an automatic control system to the basic diesel generator set. It has the function of automatic start.When the mains power is suddenly cut off, the unit can automatically start, switch, run, power, and stop automatically. When the oil pressure is too low, the oil temperature or the cooling water temperature is too high, it can automatically send out an audible and visual alarm signal : When the generator set is overspeed, it can automatically stop emergency to protect the generator set.

3. Microcomputer automatic control diesel generator set consists of diesel engine, three-phase brushless synchronous generator, automatic fuel supply device, automatic oil supply device, automatic cooling water supply device and automatic control cabinet. Automatic control application programmable logic controller (PLC) control.In addition to self-starting, self-switching, self-running, self-injection and self-shutdown functions, it is also equipped with various fault alarms and automatic protection devices. In addition, it is connected to the host computer through the RS232 communication interface for centralized monitoring, which can force control, remote signaling and back-testing, and realize the requirement of unattended operation.

The above is an introduction to the different types of diesel generator sets. For the current power curtailment situation, users can equip the company with suitable diesel generator sets according to their actual conditions.
