Analysis and Calculation of Total Supply Capability of Vessel DC Zonal Electric Distribution System During Motor Start-up
摘要
Abstract
According to new characteristics of the vessel integrated power system (VIPS) utilizing DC zonal electric distribution and with a safe start-up of the motor as a goal,this paper offered a total supply capability (TSC) model for primary load transfer in the DC zonal electric distribution system (DC-ZEDS) based on the inverter load rate.The adoption of the concepts of virtual contact matrix and comprehensive load transfer matrix leaded to an expression for secondary load transfer matrix and also an analytical expression for the maximum inverter load rate.Then,a TSC model for secondary load transfer based on the overload constraints of the inverters had been built on the particular structure of the DC-ZEDS.Finally,the TSC of primary load transfer and the maximum inverter load-rate vector were respectively calculated under the safe operation of the inverters and the overloading operation of the intra-regional direct contact inverter.Through analyzing the possibility of the inverter overloading after primary load transfer and further using the analytical and modeling methods,the TSC of secondary load transfer could be obtained,and several different groups of maximum inverter load-rate vectors were given according to allowable balance in load rate between the inverters.Thus,the load shedding caused by the motor start-up can be overcome so as to determine the safe operation boundary of DC-ZEDS.All this will provide a basis for researching the preventive control of the VIPS.关键词
