Abstract

This paper proposes a new power generation centre (PGC) for the engine of more electric aircraft (MEA) application. In this PGC, a starter/generator is connected to the high-pressure (HP) spool to start the engine in the start process and generate electric power in the other working modes, and a generator is attached to the low-pressure (LP) spool. Their outputs supply a common DC bus via active rectifiers. A back-to-back (B2B) converter is deployed to connect the AC sides of the two generators. There are several benefits by introducing such a B2B converter into the system, and one of the major attractive points is that the B2B converter provides an additional power flow path to the generators under HP or LP converter fault scenarios hence improving the post fault operation ability. The characteristic of post fault operation ability of the proposed PGC will be articulated in this paper. Besides, modelling, analysis and controller design of the system will be illustrated in detail. The effectiveness of proposed power generation center and its controllers is verified in Simulations.
