根据舰船综合电力系统(IPS)采用直流区域配电的新特点,针对电动机起动带来的逆变器过载问题,在电动机安全起动的前提下,以最小化开关操作代价为目标,分别建立负荷一次转供模型和负荷二次转供模型。然后,通过比较不同工况下直流区域配电系统(DC-ZEDS)的负荷量与负荷转供最大供电能力(TSC)模型给出的安全边界之间的大小关系,同时,考虑负荷优先级的不同,给出了DC-ZEDS的重载询问流程。最后,针对不同工况下的负荷分布情况,提出相应的预防控制策略,解决了因电动机起动可能造成的逆变器过载问题,并最大限度地避免了切负荷操作。
According to the new characteristics of IPS in power distribution system, aiming at the overload problem of inverter caused by motor starting, under the premise of safe starting of motor, aiming at minimizing the switching operation cost, A model for the transfer and load transfer model. Then, by comparing the size of the DC-ZEDS load and the safety margin given by TSC model under different operating conditions, and considering the relationship between load priority Different, given DC-ZEDS overloaded query process. Finally, according to the load distribution under different conditions, the corresponding preventive control strategy is put forward to solve the inverter overload problem caused by the motor starting, and to avoid the load-shedding operation to the maximum extent.
