Deeply understand the classification of diesel generator sets.

Diesel generator set is a kind of power supply equipment which takes diesel engine as the prime Mover and drives synchronous generator to generate electricity, and it is widely used in many fields. There are many types of them, and the following is a detailed introduction to their main classification methods.According to the purpose, it can be divided into common generator sets, standby generator sets and emergency generator sets. Commonly used generator sets run all the year round, generally located in areas far away from the power grid (or commercial power) or near industrial and mining enterprises to meet the construction, production and domestic electricity consumption in these areas. The standby generator set is used when the power supply is interrupted, and it is usually in a standby state. When the power supply is cut off, it can quickly start power supply to ensure the normal operation of important equipment, which is common in hospitals, data centers and other places with high requirements for power continuity. Emergency generator sets are mainly used for instantaneous power failure after emergency or accident power failure, which can quickly restore and extend a period of power supply time. This kind of generator sets usually require short start-up time and high start-up success rate, and are mostly used for power supply of emergency equipment such as firefighting and elevators.According to the control mode, there are manual drive units, self-starting units and microcomputer-controlled automation units. Manual motor group needs manual operation to complete the actions such as starting, stopping, closing and opening, which is suitable for occasions where the continuity of power supply is not high and the operator can respond in time. The self-starting unit can automatically start, close and supply power to the load when the power supply fails, and can automatically stop and open the brake after the power supply returns to normal. The operation is relatively simple, and it is often used in some places where there is a certain demand for power supply. Microcomputer-controlled automatic unit is fully controlled by microcomputer system, which has more powerful functions, such as fault self-diagnosis, remote monitoring, etc., and can realize high automation and intelligent management, and is widely used in places with high requirements for power quality and reliability, such as large data centers and financial institutions.According to the output voltage and frequency, it can be divided into AC generator set and DC generator set, and AC generator set can be subdivided into single-phase generator set and three-phase generator set. Single-phase generator sets output single-phase alternating current, which is generally used for equipment with low power and single-phase load, such as small lighting equipment and small power tools. Three-phase generator sets output three-phase alternating current, which can provide stable power support for most industrial and commercial equipment and are widely used. DC generator sets output DC power, which is often used in some equipment with special requirements for DC power supply, such as some communication equipment and DC motors.According to the speed classification, there are high-speed diesel generator sets, medium-speed diesel generator sets and low-speed diesel generator sets. The speed of high-speed diesel generator set is usually 1000-1500 rpm, which has the advantages of small size, light weight and fast start-up. However, the relative vibration and noise are large, so it is often used in occasions with high requirements for space and start-up speed. The speed of medium-speed diesel generator set is generally 500-1000 rpm, and its performance is relatively balanced, which is suitable for medium-scale power demand scenarios. Low-speed diesel generator sets, with a rotating speed of less than 500 rpm, usually have large single power and good stability, but they are bulky and heavy, and are mostly used in places with great power demand, such as large ships and large power stations.Different types of diesel generator sets have their own characteristics and applicable scenarios. Users can reasonably choose the appropriate diesel generator set according to their actual needs, such as power load, use environment, reliability requirements for power supply and other factors.
