The method of research on ship electric propulsion system using the braking energy feedback

In marine electric propulsion system,the feedback of braking energy can lead to pump lift voltage,it is harmful to the variable frequency speed regulation system,and even affects the normal work of the whole grid system. Therefore,it must take certain method to consume the energy. In traditional marine electric propulsion system,it always uses the braking resistance to consume the feedback of energy,but it cannot be reused. It proposes the usage of variable flow control technology. The large amounts of braking energy will be reused in this way. The method can improve the efficiency of the utilization rate of electric propulsion system,and has the vital significance to promote the development of the ‘green ship'.
