How do Diesel Generators work?
A diesel generator is used to generate electric energy by using a diesel engine with the help of an electric generator. Diesel gensets convert the mechanical energy generated by the diesel engine into electricity using alternators. An alternator comprises of a rotor (a moving component that produces rotating magnetic field) and a stator (a stationary set of electrical conductors wound in coils over an iron ore). The rotor generates a moving magnetic field around the stator and thus voltage difference is induced between the windings of a stator. This is how electricity is produced by the generator.
Features of Diesel Generators
- Power Output: The power output range of diesel generators is very wide and can be classified accordingly. Diesel generators used for industrial purposes are generally large in size and can provide a great deal of power for a long period of time. They are generally used by industries where power demand is high. Whereas diesel generators used for domestic purposes are very small in size and provide power up to a limited range. They are ideal for use in houses, small shops and offices.
- Cooling: Air cooled diesel gensets rely on air to provide the cooling function for the generator. No additional part, except for an air intake system is used. Liquid cooled diesel generators rely on liquids for cooling and comprise of a separate system for achieving this function.
- Control systems and power management systems: Modern day diesel generators have the ability to automatically transfer the source of power supply from the grid to the generator during a power cut and vice versa. They can also display warning messages (low fuel and other performance issues) along with providing a broad range of analysis data, which in turn helps to increase the efficiency of the diesel generator.
