A generator set refers to power generation equipment that can convert mechanical energy or other renewable energy sources into electrical energy. Commonly seen generator sets are usually driven by steam turbines, water turbines, or internal combustion engines (such as gasoline engines, diesel engines, etc.). Renewable energy sources include nuclear energy, wind energy, solar energy, biomass energy, marine energy, and others. Due to the relatively large capacity of diesel generator sets, their ability to operate in parallel and provide continuous power for extended periods, and their capability to operate independently without paralleling with the regional power grid—thus not being affected by grid failures—they have high reliability. Especially in areas where the utility power supply is not very reliable, diesel generator sets are used as backup power sources. They serve as emergency power supplies and, through reasonable optimization of low-voltage systems, allow some important loads to be powered during outages. Therefore, they are widely used in engineering projects.
