摘要
单独式供电结构的飞机外部交流供电方案存在静变电源数量多、管理和维护困难、成本高以及使用率低等缺点。本文提出了基于400Hz电力系统的集中式飞机外部供电设计要求和设计方法,并对其中的关键技术进行分析,包括400Hz电力系统的结构及功能分配、母线电压等级、配电结构和潮流分析等。以上海浦东国际机场1号航站楼的飞机外部供电为实例进行了400Hz集中式供电系统的方案设计和参数分析。计算和仿真结果表明基于400Hz电力系统的集中式飞机外部供电可保证供电可靠性和电能质量,同时可以降低成本,提高供电灵活性和设备利用率。结果证明了本文所提方案的合理性。
The ground power supply for aircrafts based on independent structure has many shortcomings such as vast numbers of ground power units,difficult administration and maintenance,high cost and low utilization rate.This paper proposes the design requirements and design method of centralized ground power supply for aircrafts based on 400 Hz electric power system.The key technical problems are discussed such as the structure and functions of the proposed 400 Hz electric power system,the voltage class of busbar,the power distribution structure and the load flow analysis.Taking the Terminal 1of Shanghai Pudong International Airport for example,this paper analyzes the structure and key parameters of 400 Hz centralized power supply system.The practical calculation and simulation results illustrate the rationality of the structure and parameter design.The results also indicate the feasibility of the centralized ground power supply based on 400 Hz electric power system,because it can guarantee the reliability and quality of power supply,reduce the cost,and improve the flexibility of power supply and the utilization rate of installations.
