基于全控型PWM变流器的船舶轴带发电机系统研究

传统的以半控型晶闸管逆变的轴带发电机控制系统较简单,但存在对船舶电能质量影响大,负载适应能力差,且需要依靠同步发电机补偿无功等缺点.本文介绍了一种新型的轴带发电机控制模式,利用全控型PWM整流器的四象限运行功能,对功率进行解耦控制,实现有功控制,无功补偿.对整个系统的主电路与控制方案进行了仿真研究,结果表明,这种新的轴带发电机控制能够克服原有系统的不足,具有充分的可行性与较大的优越性.

The research of a newshaft generator system on the ship based on the whole controlled PWM rectifier

The traditional shaft generator has a simple control which based on the thyristor inverter,but it has more affections to the quality of the power and is difficult to adapt the large load on the ship,it also need a synchronous generator to compensate the var.In this paper a new shaft generation control system is described,it is basing on the whole controlled PWM rectifier which can work on the four quadrant and achieve the distribution of the power.The given main circuit and the project of the control system...
