摘要

They are known operational limitations that cause the electrical system of a ship, the starter of electrical bow thrusters. Normally during this operation has appealed to generator dedicated exclusively to such motors, for this purpose, or dispose of any of the auxiliary power plant off the bar bus and thus limiting the consumption of power available inside the ship. This way of design or operating the electric system during operations in port, is conditioned by the high starting current that need asynchronous electric motors and their strong reactive, which leads, temporarily, significant voltage droops and changes in the frequency in the transient response of the generator. These variations can be accepted by the electrical bow thrusters, increasing his start cycle, or for any resistive load, but are unacceptable for the good functioning of any other kind of dynamic or electronic load. The same problem is transferable to electric propulsion in small boats, with the aggravating circumstance that space constraints and that conditions leading to a single generator for all services. This study shows the improvements offered in these cases, the starting offset by kinetic accumulator, reducing voltage drop and the star cycle.
