Load Forecasting of Ship Electronic power systen

摘要

With the development of bigger size and more function in ships and more and more ships propelled by electric power, the demands to the ships power systems is getting larger. There are some traits in the ship's electric power, for example, the electric power dynamic control system need work frequently because of many kinds of electrical equipment, which are straight to affect the stabilization of the power system, so we need predict the change of the power load in time. In this paper, the power load forecasting technique is analyzed. Include wavelet forecasting technique, chaotic forecasting technique, and combined forecasting technique. The characteristics of various forecasting methods are pointed out. Through we predict the change of the electric power load in time and based on it we can control the change of power load with rational range by regulating the power distribution and ensure that ship power system will work well.
