【Abstract】 In the small-sized ship electric propulsion system, the serious harmonic pollution of power system is produced by variable frequency driving, which caused power system’s capacity to increase greatly and worsened the power quality, even affected the ships navigation safety. Aiming at the serious harmonic pollution of power system in ships with electric propulsion system, the topology structure of hybrid active power filter (HAPF) is improved, and a new control strategy is proposed. The working principle of the HAPF is analyzed and simulated by computer, and the effectiveness of the filter is demonstrated.更多还原
