The Attentions for Using Genset Controller On the Plateau

Jul. 17, 2020

Genset controller is mainly used to distribute the electric energy output by the generator to the user's load or electrical equipment, and to indicate the working condition of the diesel generator and to maintain the voltage stability of the generator under the condition of load change.

 

Genset control panel is usually equipped with voltmeter, frequency meter, ammeter, power meter, three-phase current conversion switch, three-phase voltage conversion switch, voltage setting knob and various indicator lights. About oil pressure gauge, oil temperature gauge, battery charging ammeter, water temperature gauge, start button and start electric lock and other components. Some devices are directly installed on the control panel according to the description requirements, and some devices are installed on the external panel of diesel engine. The components of the internal device of the control panel are mainly related to the excitation method of the generator and the active control of the diesel engine.

 

The internal structure of diesel generator set control panel.

The simple control panel is usually equipped with voltage regulator, silicon rectifier diode, rheostat, active air switch and current transformer and other components, while the disordered control panel is equipped with overload and short circuit protection device, electronic governor, silicon controlled rectifier, relay, various safety devices and small transformer and other electrical equipment.

The use of diesel generator sets will vary according to the regional differences. The main reason is that the power of the generator has decreased, and the fuel consumption of diesel oil is still increasing, and the heat load is constantly rising. Therefore, we start from the theoretical point of view, and analyze the impact of high original environment on the performance of the generator set according to examples.

 

In plateau area, the air pressure is low, the air is thin, and the air volume containing oxygen is less. For the diesel generator with natural suction, the combustion condition will become worse due to insufficient air intake, so the diesel generator will not send out the original specified rated power. Diesel generators are basically the same, so it can be seen that their working capacity has declined in plateau environment.

 

The output current of generator set will change with the change of altitude, and decrease with the increase of altitude. Besides, fuel consumption index and electrical performance index will be added.

Due to the high altitude of the plateau, the temperature of the environment is lower than that of the plain, and the air in the plateau is thin, so the starting performance of the diesel engine is relatively poor in the plateau area. Therefore, it is suggested that the user should take corresponding temperature assisted measures when using it.

 

The boiling point of water decreases with the increase of altitude, and the air pressure and quality of cooling air decrease, which increases the increase of heat dissipation. However, since the cooling system is worse than the plain environment, it should be noted that the open cooling cycle should not be used in the plateau altitude area, and the pressurized closed cooling system can be used.

 

After all, there is a great gap between the plateau and the flat land. We must pay attention to it when purchasing and using control panel of diesel generator, otherwise it will have a great impact on the work efficiency and cause certain economic losses.
