模糊控制有源电力滤波器在电力推进船舶中应用

电力推进船舶中,由于电力电子开关器件在推进电机变频调速装置中的广泛应用,使之在船舶电力系统中产生了大量的谐波,通常的解决方案是施加无源LC滤波器装置.近年来,克服了无源滤波器种种不足的有源电力滤波器(Active Power Filter,APF)得到了快速发展,该文将APF应用到电力推进船舶的电力系统中,并将模糊控制策略分别应用到并联型APF的电流跟踪环节和直流测电压控制环节.仿真结果表明,与常规的并联型APF相比,该文提出的基于模糊策略的APF具有更好的谐波抑制性能.

Research on Fuzzy Logic Control-based Active Power Filters Applied in Electric Propulsion Ships

In the ships with electric propulsion,due to the wide use of power electronic switching devices in variable frequency speed-regulating equipments designed for driving motors,a large number of harmonics are produced in the ship power systems and the usual solution is to impose devices with passive LC filters.In recent years,active power filters(APFs) which can overcome the shortcomings of passive LC filters have been developed rapidly.Application of shunt APFs in the power system of electric propulsion ship ...
