Advantages of gas generator
Gas generators have the advantages of wide output power range, reliable start and operation, good power generation quality, light weight, small volume, simple maintenance, low frequency noise and so on. Generally, they have the following four advantages:
First, good quality of power generation
Because the generator only rotates when working, the electric adjustment reaction speed is fast, the work is especially stable, the generator output voltage and frequency precision is high, the fluctuation is small, the unit is very stable when the load is suddenly added and reduced by 50% and 75%. Electrical performance index better than diesel generator set.
Two, good start performance, high start success rate
The time from successful cold start to full load is only 30 seconds, while the international regulations stipulate that the diesel generator will be loaded in 3 minutes after successful start. Gas turbine generator set can guarantee the success rate of start-up under any ambient temperature and climate.
Three, low noise and small vibration
Because the gas turbine is in the high speed rotating state, its vibration is very small, and the low frequency noise is better than the diesel generator set.
Four, the use of combustible gas is clean, cheap energy
Such as: gas, straw gas, biogas and so on, with them as the fuel of the generator set not only reliable operation, low cost, and can turn waste into treasure, will not produce pollution.
There are many forms of generator driving power. Common power machines are:
Wind generator is to rely on the wind to drive the generator to turn, produce current; The generator consumes no extra energy and is a pollution-free generator.
Hydraulic generator is the use of water flow gap, generate power, drive the generator to generate electricity, is also the use of green natural resources to generate electricity equipment, also known as hydrogenerator.
The oil-fired generator relies on the combustion of diesel or gasoline to generate power to drive the generator set. In case of power failure, oil-fired generators can be started to generate electricity to maintain normal operation.
According to the mode of electric energy conversion can be divided into AC generator and DC generator two categories.
Alternators are divided into synchronous generators and asynchronous generators. Synchronous generators are divided into implicit pole synchronous generators and salient pole synchronous generators. Synchronous generators are most commonly used in modern power stations, while asynchronous generators are rarely used.
Ac generator sets can be divided into two types: single-phase generator and three-phase generator. The output voltage of the three-phase generator is 380V, and the output voltage of the single-phase generator is 220V.
According to the excitation mode can be divided into brush excitation generator and brushless excitation generator two categories
natural gas powered emergency generators
The excitation mode of brush-excitation generator is other excitation type, and the excitation mode of brushless excitation generator is self-excitation type. The rectifying device of the other excited generator is on the generator stator, while the rectifying device of the self-excited generator is on the rotor of the generator set.
