摘要
针对混合动力船舶采用制动电阻吸收制动能量不可避免造成能量浪费的问题,借鉴直流推进系统,采用超级电容储能装置作为能量回馈装置,研究混合动力船舶在典型工况下的制动过程,并对超级电容在制动过程中的控制方法、控制效果进行分析。结果表明:与制动电阻相比,超级电容制动能量回馈装置不仅能够提升直流母线电压的稳定性,还能有效吸收和储存在螺旋桨制动及减速过程中产生的制动能量,提升船舶能效。
Aiming at the inevitable energy waste caused by the use of braking resistance to absorb braking energy in hybrid power ships,learning from the DC propulsion system,using the super capacitor energy storage device as the energy feedback device,the braking process of hybrid ships under typical working conditions was studied・The control method and control effect of super capacitor in the braking process were also analyzed.The results show that compared with the braking resistance,the super capacitor braking energy feedback device can not only improve the stability of DC bus voltage,but also effectively absorb and store the braking energy generated in the process of propeller braking and deceleration,so as to improve the ship's energy efficiency.
