摘要/Abstract

摘要：

高压直流(HVDC)发电系统因为其效率高、质量轻以及可靠性高等诸多优点成为航空供电系统的首选,其系统输出端存在着用于滤波的大电容,这使得采用传统PI调节方案的调压器不能满足系统的动态性能要求。因此,提出了采用励磁电流前馈(ECF)的调压器技术。对该技术进行了详细的理论分析,分别建立了有励磁电流前馈环和无励磁电流前馈环的发电系统的数学模型。比较2个系统的性能,发现有励磁电流前馈环的发电系统截止频率得到了较大的提高。实验表明,在突加负载和突卸负载2种情况下,加入励磁电流前馈环控制,系统能够迅速响应,保持稳定并且超调量小,动态性能得到了明显提高。该方法可推广到不同类型的航空发电系统的调压控制中。

Abstract:

High-voltage direct-current (HVDC) power system has been the preferred aviation power supply because of its high efficiency, light weight and high reliability. The large capacitor in the system leads to the fact that the traditional regulating plan using PI cannot meet the requirements of the dynamic performance. For this, the excitation current feedforward (ECF) technology has been proposed in the regulators in the aircraft generation system. The mathematical model of the generation system with and without the ECF is built respectively to compare the dynamic characteristics of the system. Experimental results show that with ECF the system can respond quickly and remain stable, and the dynamic performance improves significantly in sudden change of the load in the system. This technology could be applied to other voltage regulators in the aircraft generation system.

Key words: doubly salient electromagnetic generator system, voltage regulating system, excitation current feedforward, modeling and analysis, dynamic characteristic
