Abstract

The invention relates to a generator excitation control system. The generator excitation control system comprises a voltage measuring circuit, a current measuring circuit, a power conversion circuit and a main control unit circuit, wherein the voltage measuring circuit measures the output voltage of a generator and outputs the measured result to a main control unit; and the current measuring circuit measures the output current of the generator and outputs the measured result to the main control unit. The generator excitation control system is characterized in that: the main control unit circuit is used for controlling the output duty ratio of the power conversion circuit according to the output of the voltage measuring circuit and the current measuring circuit. The generator excitation control system can circularly realize instant large current impact output of the generator by utilizing the system inertia of a generator set. Compared with the traditional generator set with the same capacity, the generator excitation control system is more suitable for inductive impact load of high-power air conditioners, water pumps and the like.

Description

Technical field

[0001] The invention relates to an excitation control system for a generator, in particular to an excitation control system for a medium and small alternating current generator set driven by a gasoline or diesel engine. Background technique

[0002] Among the existing general small and medium-sized gasoline and diesel AC generator sets, generator sets with excitation control devices (commonly known as automatic voltage regulators) are favored by users because of their stable output voltage and low harmonic content.

[0003] At present, the common automatic voltage regulators on the market mostly adopt the control method of output voltage closed-loop adjustment, that is, the rotor excitation duty cycle is controlled according to the generator output AC voltage: when the output voltage is high, the rotor excitation duty cycle is reduced; when the output voltage If it is too low, increase the duty cycle of the rotor excitation. This control method has good adaptab...
