幅压直流电动机-中频发电机控制技术

Control technology of DC motor & medium frequency generator group with a wide range of input voltage

幅压直流供电的电动-交流发电机组广泛应用于潜艇等由蓄电池供电的直流独立电源系统。发电机组输出交流电的供电质量受蓄电池的浮动电压和交流负载等因素影响,同时,还存在着输出电压漂移、频率不稳等现象。通过研究机组的工作特性以及独立供电的小容量系统负载冲击对机组输出电压稳定性的影响,针对影响输出电源品质的因素,采用有效的磁场补偿技术和PI控制技术相结合的方法,维持机组输出电压幅值、频率的稳定,试验验证了该方法的有效性。

The DC motor ＆medium frequency generator group with a wide range of input voltage is widely used in the independent DC power supply system powered by the storage battery in a subma- rine. However, the quality of the output voltage of the generator group tends to be affected by the network voltage of storage battery and the load, and meanwhile there appear phenomena such as out- put voltage drift and unstable frequency. This paper discusses the performance features of the group and the impact of the low-capacity independent power supply load on the output of the group. To deal with the factors affecting the gies of both magnetic field co plitude of the generator grou quality of the output voltage, it is proposed that the effective technolo- mpensation and PI control are used for maintaining the frequency and am- p. The experiment results prove that the method is effective.
