摘　　要：洋流能是一种环保的清洁可再生能源,要实现洋流能的开发利用,离不开发电设备的研究。同时也能解决深海各种传感器水下长期供电的问题,优化当前采用的锂电池供电方式,减少锂电池的更换,节省人力物力,所以,设计一种利用深海洋流能发电的系统具有十分重要的意义。在深海洋流发电系统中,这里针对洋流发电机脉宽调制(PWM)整流器提出使用模型预测直接功率控制策略替代传统电压电流双闭环的控制策略,实现发电机的单位功率因数运行,不仅提高了深海发电系统的稳定性,而且提高了发电机的运行效率,从而提高了洋流能的转换效率。Ocean current energy is a kind of environmentally friendly clean and renewable energy.To realize the devel-opment and utilization of ocean current energy,it is inseparable from the research of power generation equipment.At the same time,it can also solve the problem of long-term underwater power supply of various deep-sea sensors,opti-mize the current lithium battery power supply mode,reduce the replacement of lithium batteries,and save manpower and material resources.Therefore,it is of great significance to design a system that uses deep-sea currents to generate power.In the deep-sea current power generation system,a model predictive direct power control strategy is proposed to replace the traditional voltage and current double closed-loop control strategy for the ocean current generator pulse width modulation(PwM)rectifier,to realize the unit power factor operation of the generator,not only the stability of the deep-sea power generation system is improved,but also the operation efficiency of the generator is improved.
