Structure and Key Parameters of Centralized Ground Power Supply for Aircrafts

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 1 of 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.
