本发明是这样实现的：发电机由原动机驱动，机组起动以后，依靠剩磁产生的电压，经整流后对交流励磁机的磁场提供励磁电流，交流励磁机电枢电压逐渐升高，该交流电压经旋转整流器整流后送入主机磁场，使主发电机建立电压，在转速接近额定值时，数字自动电压调节器使发电机电压迅速上升，并将交流电压稳定在额定值。该交流电压再通过整流器整流，输出需要的直流电压。同时发电机的交流电可以通过数字自动电压调节器的开关量进行宽电压调节，此时经整流后的直流电压也随着调节。The present invention is realized in the following way: the generator is driven by the prime mover, and after the unit is started, the voltage generated by the residual magnetism is used to provide excitation current to the magnetic field of the AC exciter after rectification, and the armature voltage of the AC exciter gradually increases, and the AC voltage After being rectified by the rotary rectifier, it is sent to the magnetic field of the main engine to make the main generator build up the voltage. When the speed is close to the rated value, the digital automatic voltage regulator makes the generator voltage rise rapidly and stabilize the AC voltage at the rated value. The AC voltage is then rectified by a rectifier to output the required DC voltage. At the same time, the AC power of the generator can be adjusted in a wide range of voltages through the switching value of the digital automatic voltage regulator. At this time, the rectified DC voltage is also adjusted accordingly.
发电机在运行过程中，若因某种原因，例如：负载变化、转速变化、各绕组温度变化等，发电机端电压有升高或降低的趋势时，数字自动电压调节器能检测出这一微小的电压偏差，并迅速地减少或增加励磁电流，维持发电机的端电压近似不变。During the operation of the generator, if for some reason, such as: load changes, speed changes, winding temperature changes, etc., the generator terminal voltage tends to rise or fall, the digital automatic voltage regulator can detect this Small voltage deviation, and rapidly reduce or increase the excitation current, maintain the terminal voltage of the generator approximately constant.
不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。It is not limited thereto, and any changes or replacements that do not go through creative efforts shall fall within the scope of protection of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope defined in the claims.
