摘要/Abstract

摘要：

近年来,基于实时数字仿真器的电气系统功率硬件在环(Power hardware-in-the-loop,PHIL)仿真技术受到广泛关注,其结合了数字仿真和物理模拟的优势,可以有效提高仿真准确性,并缩短仿真系统的开发周期。然而,由于功率接口的不理想性,构建的PHIL仿真系统会存在稳定性问题。基于理想变压器(Ideal transformer,ITM)接口算法的PHIL仿真系统的理论,一种通过在受控电流源的控制信号中引入补偿信号的方法被提出,该方法在抵消并联阻抗带来的分流影响的同时保证了功率硬件在环仿真的稳定性,其对系统稳定性分析的研究可以为满足多尺度系统的联合仿真需求,为实现不同系统的联合仿真提供指导。

Abstract:

In recent years, the power hardware-in-the-loop (PHIL) simulation technology of electrical systems based on real-time digital simulators has attracted widespread attention. It combines the advantages of digital simulation and physical simulation, which can effectively improve simulation accuracy and shorten the development cycle of simulation systems. However, due to the unsatisfactory power interface, the constructed PHIL simulation system will have stability problems. Based on the theory of PHIL simulation system of ideal transformer (ITM) interface algorithm, a method of introducing compensation signal into the control signal of controlled current source is proposed. The research on system stability analysis can provide guidance for meeting the needs of multi-scale system co-simulation and implementing co-simulation of different systems.

Key words: PHIL, interface algorithm, parallel impedance
