变速恒频航空电源发电状态闭环系统模型

变速恒频（Variable Speed Constant Frequency,简称VSCF）电源是一种新型航空电源,它的主电路主要由变频交流发电机和变频器构成。本文按变频器的实际工作,归纳出系统四种基本电路结构,共十二种工作模式,分别建立了它们的状态方程,为数字计算机进行仿真计算提供了数学模型。所提供的模型对于系统的定量分析研究与优化设计是有意义的。

THE MODEL OF THE VARIABLE SPEED CONSTANT FREQUENCY CLOSED-LOOP SYSTEM OPERATING IN GENERATING STATE

The variable speed constant frequency（USCF） electrical power system is a new type of aircraft power supply, which contains an alternating generator and a cycloconverter. This paper has summed up the work of cycloconverter, and obtained four fundamental classes of circuit construction of the closed-loop system, which have twelve operating models. The mathematical model for each fundamental class of the circuit construction has been introduced in thia paper. These mathematical models can be used in digital simulation. The result of the simulation will be significant for the optimal design of the whole system.
