摘要
在海流能发电中,因海流流速变化较大,输出电压/频率不稳定,为了实现电能的稳定输出,需要进行整流控制。在介绍了PWM整流器基本结构和数学模型基础上,结合海流能发电特点,分析了模型预测直接功率控制方法,并将其与传统直接功率控制技术性能进行了仿真对比分析,结果表明直接功率控制用于海流能发电的整流控制技术是正确可行的。
In ocean current power generation,the output voltage/frequency is unstable due to the great change of ocean current velocity.In order to achieve the stable output of electric energy,it is necessary to carry out rectification control.Based on the introduction of the basic structure and mathematical model of PWM rectifier,combined with the characteristics of current power generation,this paper analyses the model prediction direct power control method,and compares its performance with traditional direct power control technology.The results show that direct power control is correct and feasible for rectifier control technology of ocean current power generation.
