Research on marine active filter based on DSP and SVPWM algorithm

船舶电站及相应的配电网络是船舶电力设备正常运行的基础,近年来,船舶自动化程度迅速提高,船载电力驱动系统、导航定位系统、通信系统等都高度依赖船舶电力网络。因此,提升船舶电力系统可靠性、供电质量非常重要。电力网络的有源谐波是指船舶电力设备运行过程中产生的谐波干扰,作为一种非线性的负载会导致船舶电网的无功功率升高,造成电网畸变。本文利用DSP和SVPWM三向逆变器算法进行船舶谐波的有源过滤,提升船舶电网的供电质量,分别从SVPWM三向逆变器算法原理、有源滤波器结构、性能仿真等进行详细研究。

The ship power station and the corresponding distribution network are the basis for the normal operation of the ship's electrical equipment.In recent years,the degree of ship automation has been rapidly improved,and the ship's electrical drive system,navigation and positioning system,communication system,etc.are highly dependent on the ship's electrical network.Therefore,it is very important to improve the reliability and power supply quality of marine power system.The active harmonic of power network refers to the harmonic interference generated during the operation of marine electrical equipment.As a nonlinear load,it will lead to the increase of reactive power of the marine power grid,causing grid distortion.The research direction of this topic is to use DSP and SVPWM three-way inverter algorithm to carry out active filtering of ship harmonics and improve the power supply quality of ship power grid.Detailed research is carried out from the algorithm principle of SVPWM three-way inverter,active filter structure,performance simulation and other aspects.
