在船舶电力推进中,推进电机是把电能转化为机械能的核心元件。随着科学技术的日益发展,大功率永磁同步电机已经在电力推进系统中广泛运用。由于舰船系统外部扰动大,会对推进部分交流调速系统带来很大影响。滑模变结构控制受外部扰动因素小,响应快速,因此本文把滑膜变结构控制应用于交流调速系统中,采用id=0的矢量控制策略,建立了船舶推进交流调速系统仿真模型。仿真结构表明,采用滑膜变结构控制进行交流调速,能加快永磁同步电机的推进时间,同时外部扰动对调速影响减小,能够满足船用大功率电机在动态转矩响应方面的要求。
Ship electric propulsion, propulsion motor is to convert electrical energy into mechanical energy of the core element. With the increasing development of science and technology, high-power permanent magnet synchronous motor has been widely used in electric propulsion systems. Due to ship large disturbance outside the system, will restructure some AC drive system have a great impact. Variable structure control by a small external disturbance factors, rapid response, this paper is applied to the synovial VSC AC drive system, the establishment of ship propulsion AC speed control system simulation model. Structure simulation showed that synovial variable structure control AC speed, can accelerate the time of permanent magnet synchronous motor, while reducing the external disturbance influence on the governor, and to meet the marine power motors in dynamic torque response requirements.
