船舶典型电力负荷模型仿真验证研究

Research on Simulation and Verification of Typical Ship Power Load Model

电力负荷是船舶电力系统的重要组成部分,目前对于船舶发电机组以及配电网络的仿真模型研究取得了较多的成果,但在电力负荷仿真模型方面,还有待补充完善。建立船舶电力负荷模型的难点在于船舶电力负荷数量多、特性差异大,很难建立一个通用的模型反映所有电力负荷的特性。需要根据电力负荷的特性,进行合理的归类和简化,通过建立典型电力负荷模型,初步反映船舶电力负荷的特性。本文对船舶电力负荷的分类进行了初步研究,根据负荷的状态分为电动机负荷和静止负荷,并建立了相应的仿真模型。通过具体算例验证了恒阻抗负载,恒电流负载,以及恒功率负载和电动机负载仿真模型的正确性,本文的研究成果丰富了船舶电力系统仿真模型的基础,为进一步开展船舶仿真研究奠定了基础。

Recently,many achievements have been made in the simulation model of ship generator sets and distribution networks,but power load simulation models need to be improved.Due to a large number of ship power loads and different characteristics,it is difficult to establish a general model to reflect the characteristics of all kinds of power loads.According to the characteristics of power load,it is necessary to reasonably classify and simplify the loads.In this paper,the ship power loads are divided into two categories of static and motor load,the simulation models of them are established,and the correctness of the simulation models of constant impedance load,constant current load,constant power load and motor load are verified by simulation examples.The research results of this paper could enrich the simulation model base of ship power system and lay a foundation for further simulation of ship power system.
