摘　　要：介绍以三相变流器为主电路结构的静止无功发生器(SVG)装置的工作原理,结合电力电子的静止无功补偿技术及其最新发展阐述基于三相电路瞬时无功功率理论的无功电流和谐波的检测方法,对采用瞬时无功功率理论控制方法的静止无功发生器在船舶轴带发电机系统中的应用进行研究, 并给出系统基于Matlab的仿真。根据船舶轴带发电机的特点和仿真结果,有效地验证了在船舶轴带发电机系统中采用静止无功发生器取代同步补偿器的可行性。The principle of a static var generator (SVG), which employs a three-phase voltage source inverter,is introduced. Combining with the static reactive power compensable technology and its latest development, the detected method of reactive power and harmonic wave based on a three-phase instantaneous reactive power theory is described. The application of SVG based on the control strategy of instantaneous reactive power theory in marine shaft generator system is studied. Simulated results of the system obtained with Matlab are also given. According to the characteristics of marine shaft generator system and the simulated results, it has proved to be feasible to replace the synchronous compensator with SVG in the marine shaft generator system.
