Problems solved by technology
When the generator set is suddenly loaded or unloaded, it is difficult to quickly restore the speed of the generator rotor to the set value through the way the engine drives the generator rotor to rotate, which makes the frequency of the generated electric energy very unstable and difficult to meet index

The invention discloses a generator constant speed control apparatus. The apparatus includes an engine unit, a motor unit, and a planetary gear. The planetary gear comprises a sun gear, an inner gear ring and a constant-speed output shaft, the constant-speed output shaft is connected with a generator, the engine unit comprises an engine, the engine is connected with the sun gear, the motor unit comprises a motor, and the motor is connected with the inner gear ring. When the load torque of the generator is changed, the rotating speed of a generator rotor is difficult to recover to the set value quickly by considering that the generator rotor is only driven to rotate by the engine, so that the manner that the motor and the engine are matched with each other is adopted, and the generator recovers to the original rotating speed. The rotating speed of the inner gear ring is adjusted through the motor, the rotating speed of the sun gear is adjusted through the engine, and the rotating speed of the generator connected with the planetary gear is recovered to the original rotating speed together.
Description
technical field [0001] The present application relates to the field of generator control, in particular to a generator constant speed control device and method. Background technique [0002] A generator set (Generators Set) is a complete set of mechanical equipment that converts other forms of energy into electrical energy. A conventional diesel engine generator set converts fuel combustion energy into mechanical energy and transmits it to a generator, which is then converted into electrical energy by the generator. At present, an engine is usually used to drive the rotor of a generator to rotate. For example, a diesel engine generates energy by burning diesel oil, and works on the generator so that the generator can operate normally. The frequency of generator power generation will change accordingly with the change of the rotor speed of the generator. For example, when the rotor speed is 1500 rpm (revolution(s) per minute, rpm), the power generation frequency is 50Hz, and ...
