Control Strategy of a Doubly Salient Structure Starter/Generator System

介绍了一种可以适用于航空低压直流、变速恒频、高压直流电气系统的新型双凸极启动 /发电机系统( DSS/ G) ,首先对双凸极电机的电动及发电机理进行了理论分析 ,给出双凸极启动 /发电机的相应控制策略 ,启动运行时采用恒转矩控制策略 ,发电运行时采用是两极发电模式。在此基础上研制了一台 1 8k W样机 ,并进行了试验研究 ,试验结果表明双凸极电机启动 /发电系统方案具有良好的性能。

A new type of doubly salient starter/generator(DSS/G) is presented used in aircraft low voltage direct current, variable speed constant frequency and high voltage direct current systems. First, the operational theory of motor and generator is analyzed, and corresponding control strategies are given for starting and generating model. Constant torque control is rea-lized by chopping current in starting mode, and two stage generating mode is used. A 18 kW prototype is implemented to verify system performance. It is shown that the DSM S/G system possesses simple structure, high efficiency and flexible control.
