The invention discloses a servo energy-saving internal combustion engine generator set and a control operation method thereof. A closed-loop control system composed of a power generation voltage error calculator, a power generation voltage regulator, a three-phase excitation current regulator, a slip ring, a generator and a generator output voltage sampling unit carries out closed loop on an output power generation voltage amplitude of the generator, so that the stability of the power generation voltage amplitude is ensured. Meanwhile, a closed-loop control system composed of an excitation frequency calculator, a rotor frequency calculator, a position and rotating speed detection unit, a position and speed sensor, a three-phase excitation current regulator, a slip ring and a generator accurately controls the output alternating current frequency of the generator. In addition, the phase of the generator is accurately controlled through the closed-loop control system formed by a phase difference detection control unit, the three-phase excitation current regulator, the slip ring and the generator. According to the invention, the power generation frequency is stable, the voltage is stable, the phase is randomly adjustable, and grid connection with commercial power, multi-machine networking or single-machine operation can be conveniently carried out.
Description
technical field [0001] The invention relates to the technical field of internal combustion engine generator sets, in particular to a servo energy-saving internal combustion engine generator set and a control operation method thereof. Background technique [0002] Internal combustion engine generating sets (such as diesel generators, gasoline generating sets, gas generating sets, etc.) . In order to ensure the voltage stability of the generated power (such as 380VAC), the control system will adjust the magnitude of the excitation current of the generator, so that the generator can induce the required voltage at a fixed speed, and the control system will detect the current caused by the load. The voltage fluctuation caused by the change, and the closed-loop control of the output voltage of the unit is realized by controlling the magnitude of the excitation current. However, the internal combustion engine generator set based on the above-mentioned basic structure and control ...
