摘　　要：船载大功率脉冲负载运行会产生间谐波电流浪涌及功率冲击,导致发电机轴承振动、磨损甚至发生机械故障。为解决脉冲负载间谐波功率波动与脉冲参数定量关系不清以及不同脉冲参数下间谐波功率难以补偿的问题,提出舰船脉冲负载间谐波功率快速跟踪自适应补偿方法,该方法能够根据间谐波功率定量关系快速响应脉冲负载冲击,实现对间谐波功率波动的补偿。建立脉冲负载间谐波功率波动幅度与脉冲负载周期、功率、占空比间的定量关系,得到其幅频特性函数;提出混合储能快速跟踪补偿方法,根据幅频特性函数获取波动频谱范围,并与功率谱分析结合确定滤波参数,经相位延迟处理后输出控制信号。利用RT-LAB搭建含脉冲负载的中压直流舰船微网模型,算例结果验证了间谐波功率定量关系的合理性,表明该方法能够实现混合储能的优化协调,自适应补偿间谐波功率波动,增强发电机运行可靠性。Shipboard high-power pulse load operation will produce interharmonic current surges and power shocks,resulting in generator bearing vibration,wear and even mechanical failure.In order to solve the problem of unclear quantitative relationship between interharmonic power fluctuation and pulse parameters and the difficulty of interharmonic power compensation under different pulse parameters,this paper proposes a fast tracking adaptive compensation method for interharmonic power fluctuation of shipboard pulse loads,which can quickly respond to pulse load shocks according to the quantitative relationship of interharmonic power and achieve the compensation of interharmonic power fluctuation.The quantitative relationship between the amplitude of interharmonic power fluctuation and the pulse load period,power and duty cycle is established,and its amplitude-frequency characteristic function is obtained.A fast tracking compensation method for hybrid energy storage is proposed,in which the fluctuation spectrum range is obtained according to the amplitude-frequency characteristic function,and the filtering parameters are determined in combination with the power spectrum analysis.The control signal is output after phase delay processing.RT-LAB is used to build a medium-voltage DC naval microgrid model containing pulse loads.The results verify the rationality of the quantitative interharmonic power relationship,showing that the method can realize the optimal coordination of hybrid energy storage,adaptively compensate interharmonic power fluctuations,and enhance the reliability of generator operation.
