Abstract

According to a traveling power generation slow start control method for an asynchronous generator, the technical problem that slow start is slow and unstable in the generator output voltage establishment process in the prior art can be solved. The method comprises the following steps that S100, when the rotating speed of a generator is lower than a set rotating speed or the bus voltage is lower than a set voltage, a set slip f<slip_1> is given, a power device of a generator controller is controlled to generate electricity, and the voltage is increased; S200, when the rotating speed of the generator is higher than the set rotating speed or the voltage is higher than the set voltage, a set slip f<slip_2> is given, a power device switch is controlled, and the bus voltage of the generator controller is continuously increased; and S300, when the bus voltage reaches a set value, the set value and the current bus voltage are subtracted, the difference value is controlled by a regulator, the power device switch is continuously controlled, and the bus voltage is stabilized at the set value. The possibility of voltage buildup failure can be reduced, the voltage buildup process is accelerated, and overshoot when the target voltage is reached is reduced.

Description

technical field [0001] The invention relates to the field of vehicle-mounted power generation technology, in particular to a method for controlling the slow start of an asynchronous generator while driving. Background technique [0002] The emergence and development of vehicle-mounted power generation power supplies have been around for a long time. Most of them are used in military combat vehicles to provide sufficient power for radar, computer and communication equipment. With the continuous advancement of power electronics technology and the automotive industry With the rapid development of assembly technology, some large civilian vehicles, such as emergency rescue vehicles, temporary communication auxiliary vehicles and even RVs, which are loaded with more electrical equipment, are equipped with vehicle-mounted power generation power systems. At present, the power generation system drives the generator through the belt or shaft during the running of the vehicle. The gene...
