电力电子化趋势下的舰船电力系统面临的主要问题

未来舰船高能武器的规模化装舰,使二代综合电力系统的深度电力电子化成为其最主要的特性之一。电力电子化趋势下的舰船电力系统面临一系列的新问题与挑战:系统中大功率变流器和逆变器数量较多且发挥着重要的作用,小惯性环节与大惯性环节的交互作用非常复杂,系统动态特性大为改变,过渡过程缩短,次同步、超同步振荡问题逐步显现等。因此,亟需针对电力电子化这一大背景下的舰船电力系统中遇到的问题进行系统地梳理和探讨,作为后续理论方法研究与系统设计的铺垫。

Major Problems of Ship Power System with Development of Power Electronicization

The large-scale application of high-energy weapons on warships makes the deep electronic power electronization of the second-generation integrated power system to be one of its main features.The ship power system with the development of power electronization faces a series of new problems and challenges,such as a large number of high-power converters and inverters in the system which play an important role,the complex interaction between the small inertia link and large inertia link,the greatly changed dynamic characteristics of the system,the shorten transition process,and the gradually appeared sub-synchronous and super-synchronous oscillation problems.Therefore,it is urgent to systematically sort out and discuss the problems that can be encountered in the ship power system under the background of power electronization,as a basis for the further theoretical research and system design.
