Features Compared with steam turbine generator sets, diesel generator sets have the following characteristics: ①The output per unit is small in size, light in weight, and simple in system. Generally, it is integrated. Therefore, the construction of diesel power stations is fast. ②The thermal efficiency of diesel engine power generation is relatively high, and the fuel consumption per unit output does not change much at part load or light load. ③The starting, loading and stopping time of diesel generator set is relatively short, it can be started at any time, and it is more suitable for emergency power supply. ④ The operation and maintenance of diesel generator set is simpler and more convenient than that of steam turbine generator set. However, diesel generator sets also have some disadvantages: ① Only liquid fuel can be used, and the fuel price is more expensive, so the cost of electricity is higher. ②The diesel engine wears a lot, has a short life span, and is frequently overhauled. Operational stability and overload capacity are worse than steam power plants. ③ The vibration and noise of the unit during operation are large, and the operating conditions of workers are poor.
