A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1] This is a specific case of an engine generator .
An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a four-pole motor (two pairs of poles on stator) powered by a 60 Hz source, the synchronous speed is 1800 rotations per minute (rpm) and 1500 RPM powered at 50 Hz. The motor always turns slightly slower than the synchronous speed.
A direct start system as used on a marine slow-speed diesel is required to have up to 12 starts on a non-reversing engine or 6 starts on a reversible, or geared, engine. When starting the engine, compressed air is admitted to whichever cylinder has a piston just over top dead center , forcing it downward. [ 2 ]
The combined cycle power plants consist of few stages with varying startup times with more than 8 hours required to get to full power from cold state: [5] the gas turbine can start in 15-30 minutes; the steam turbine (ST) heating process takes from 1 hour (for hot startup) to 6 hours (for cold startup);
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
Colin Petersen, the original Bee Gees drummer who was credited on four of their albums, has died aged 78.. Representatives for the Australian musician and former child actor confirmed that he died ...
Constant speed drive for Boeing 727, made by Sundstrand Corporation. A constant speed drive (CSD) also known as a constant speed generator, is a type of transmission that takes an input shaft rotating at a wide range of speeds, delivering this power to an output shaft that rotates at a constant speed, despite the varying input.
