There are gas turbine generators, diesel generators, hydroelectric generators, and wind turbines on the market. The performance, scope of use, and market conditions of different types of generator sets also vary, and generator sets should be selected reasonably. Gas generator sets are generally used for constant load, and the fuel used is natural gas, which has the advantages of wide output power range, high starting and operating reliability, good power generation quality, small size and light weight, simple maintenance, low low-frequency noise, low cost, and environmental protection. However, natural gas needs to be obtained locally, and there is no large-scale distribution of natural gas energy in China, which affects the supply range. In addition, there are safety hazards for less professional users. Diesel generators are usually used as emergency or backup power sources, and the fuel used is diesel, which is a non renewable resource and relatively expensive. However, diesel is more convenient to purchase and store than natural gas, with a large single unit capacity, a wide range of uses, high thermal efficiency, low fuel consumption, fast start-up, and mature maintenance technology. Therefore, diesel generators are generally the most commonly used in the market. Hydroelectric power generation units are generally used in various hydropower stations, with the characteristics of low cost, small size, light weight, simple structure, reliable operation, and easy installation and use. They are suitable for rural households in mountainous areas with hydropower resources to solve power generation equipment such as lighting and television, but they need to have abundant water resources. Wind turbines utilize natural energy, are pollution-free, and belong to renewable energy. They are much better than diesel power generation, but they are not as effective as diesel generators for emergency use. Wind turbines cannot be considered as backup power sources, but they can be used for a long time. It is generally suitable for use in areas far from the power grid, pastoral areas with abundant wind resources, mountainous areas, islands, and other regions. In addition, there is still a big gap between the cost and technology and the traditional thermal power and hydropower, which also needs the support of national policies. Therefore, diesel generator sets are generally preferred as power generation equipment in engineering.
