摘　　要：港口总电力负荷计算通常采用需要系数法。码头装卸设备装机容量在港口总装机容量中占比较大,装卸设备需要系数选取将直接影响港口总电力负荷值,而需要系数的取值多数依靠经验,暂无明确的评价标准。针对常规负荷计算方法的不足,提出一种基于实时仿真的负荷计算方法,利用PSCAD电力系统仿真软件,根据装卸设备的技术参数,仿真港口设备实时的负荷波形,进而准确计算出港口设备总电力负荷。仿真结果表明,该方法可进一步提高负荷计算的准确性。The demand coefficient method is usually used to calculate the total power load of a port.The installed capacity of handling equipment is relatively large in the total installed capacity of the port,and the selection of handling equipment demand coefficient will directly affect the total power load value of the port.However,the value of the demand coefficient mostly depends on experience,and there is no clear evaluation standard.To improve the method of load calculation,this paper proposes a load calculation method based on real-time simulation using PSCAD power system simulation software,it can simulate the real-time load curves of port equipment according to the technical parameters of handling equipment,and then accurately calculates the total power load of port equipment.The simulation results show that this method can further improve the accuracy of load calculation.
