Abstract

This paper presents a novel integrated starter-generator system consisted of engine, open-winding permanent magnetic synchronous machine, storage battery, voltage source converter (VSC) and rectifier for overcoming the difficulties of voltage regulation and narrow speed range of conventional integrated starter-generator system based on permanent magnetic machine. In the proposed system, one side of the generator is connected to rectifier, the other side is connected to VSC for output voltage regulation. This paper studies two control strategies, id = 0 control and unity power factor (UPF) control, of open-winding permanent magnetic synchronous generator (PMSG) by theoretical analysis, derivation of formulas and simulation, the results indicates that the system is capable of output voltage regulation over the load and speed changes, the power of the generator, storage battery and load are balanced by the bi-directional electronic converter VSC, the power factor of generator decreases accordingly when the load current increase at id = 0 control strategy, and the unity power factor is obtained when UPF control strategy is taken, comparative analysis is presented at the end of this paper.

开绕组永磁发电机控制策略研究

针对传统永磁起动发电机一体化系统存在的电压调节和调速范围窄的问题，提出了一种由发动机、开绕组永磁同步电机、蓄电池、电压源变换器(VSC)和整流器组成的新型起动发电机一体化系统。在该系统中，发电机的一侧连接整流器，另一侧连接VSC进行输出电压调节。通过理论分析、公式推导和仿真，研究了开绕组永磁同步发电机(PMSG)的两种控制策略，即id = 0控制和单位功率因数(UPF)控制。结果表明，该系统能够对负载和转速变化进行输出电压调节，发电机、蓄电池和负载的功率通过双向电子变换器VSC实现平衡。在id = 0控制策略下，负载电流增大时发电机功率因数相应减小，采用UPF控制策略时发电机功率因数为单位，最后进行了对比分析。
