Power plant generators

It has the performance of long-term, uninterrupted and stable power generation, extremely high reliability, excellent fuel economy and long service life, and is the core equipment of the energy and power industry.

Continuous power station generators are not used for occasional emergencies, but as the primary or important source of electricity to meet the stringent requirements of being the main power source. Continuous power plant generators are the backbone of the power grid, usually used in thermal power plants (coal-fired, gas-fired), nuclear power plants, large hydropower plants, biomass power plants, geothermal power plants, and other occasions. In some remote areas, mining areas, factories, or places where it is impossible to connect to the power grid, self owned "continuous power stations" will be established, using large diesel or gas generator sets for continuous power supply.

Significant design requirements for generators used in sustainable power plants

Running time: Designed for 7x24 hours uninterrupted operation, with a lifespan of tens of thousands of hours.

Load rate: Often operates at high loads (such as 70% -100%) to generate electricity efficiently.

Structural strength: More sturdy and durable, with reinforced design of key components such as engine cylinder block, crankshaft, bearings, etc. to withstand long-term wear and tear.

Cooling system: The cooling system (radiator) has a larger capacity and higher efficiency, ensuring stable temperature under long-term high load.

Fuel economy: Extreme emphasis is placed on fuel efficiency, as fuel costs are the main operating costs of sustainable power plants.

Maintenance cycle: The maintenance plan is based on the number of operating hours, with more frequent maintenance and higher requirements.

Common types of generator sets for continuous power plants

Gas turbine generator set:

Features: High power, fast start-up, relatively clean emissions. Commonly used in urban peak shaving power stations, combined cycle power stations, and distributed energy stations.

Applicable to areas with sufficient natural gas supply.

Gas internal combustion generator set:

Features: High power generation efficiency and mature technology. Can be used for continuous power plants fueled by biogas, coalbed methane, natural gas, and other fuels.

Heavy duty diesel generator set:

Features: High reliability, easy access to fuel. It is a common choice for primary power sources in remote areas, island power stations, and large enterprise owned power stations.

Steam turbine generator set (non direct drive):

Characteristics: In coal-fired, nuclear, solar thermal, biomass incineration and other power plants, steam is generated by boilers or reactors to drive steam turbines, which in turn drive generators. This is the largest continuous power generation method.
