Problems solved by technology

For a synchronous generator driven by an engine, such as figure 1 As shown, the input shaft of generator 1 is connected to the output shaft of engine 3. Since the generator is coaxially driven by the engine, the speed of the engine should be stable at 1500r / min or 1800r / min, and the optimum speed of the engine is related to the power generation The rotation speed of the engine is not exactly the same. For example, the optimal rotation speed in the best performance curve of the engine above 10kw is 2200r / min to 2650r / min. The existing synchronous generators driven by the engine all use the speed regulating device to control the rotation speed of the engine. Adjustment, such as 200910186446 "Small Generator Set Speed ​​Control Device", 201110450860 "Generator Electronic Speed ​​Control Device and Speed ​​Control Method", that is, in order to meet the speed of the generator, the engine cannot work under the best working condition, and the economy is poor. Both emissions and service life are affected

Abstract

The invention belongs to generator units and particularly discloses a speed governing generator unit. According to the technical scheme, the speed governing generator unit comprises a generator, an engine speeder and an engine and is characterized in that the generator is connected with the engine through a transmission. According to the arrangement, the engine runs at the optimal rotation speed, thereby being long in service life; the engine smaller is employed under the same power, so that the product is smaller in size and lower in cost; less oil is required, and noise is lower; due to less exhausted air quantity, the energy conservation and environment protection function is imparted to the speed governing generator unit as compared with the conventional generator unit.

Description

technical field [0001] The invention relates to a generating set, in particular to a speed-adjusting generating set. Background technique [0002] According to the relationship between generator frequency, rotational speed and magnetic pole logarithm: f=pn / 60 where P is the magnetic pole logarithm, n is the rotational speed per minute, and f is the frequency. When the machine is n=1500r / min, the generating frequency of the generator is: f=pn / 60=2x1500 / 60=50(Hz), the speed of the motor is proportional to the output frequency, since P is a fixed value, usually an integer of 2 times, and the design frequency of electrical equipment is a constant value, so the generator speed should also be kept at a constant value. At present, there are two types of generator frequencies, 50 Hz and 60 Hz, which means that the generator speed is the best Stable at 1500r / min or 1800r / min. For a synchronous generator driven by an engine, such as figure 1 As shown, the input shaft of generator 1...
