摘要
提出了结合物理模拟与数字仿真实现电力系统联合仿真的技术。以替代定理为基础阐述了联合仿真的理论基础,并提出了联合仿真系统的总体布局。数字仿真接口用A/D转换通道与受控注入电流源实现,物理仿真接口用基于直流耦合的背靠背变流器结构的放大电路实现。最后通过实验验证了该技术的可行性。
A joint simulation technology for power system, in which the physical analogue and digital simulation are combined, is proposed. On the basis of substitution theorem the theoretical base of joint simulation is expounded and the overall layout of the joint simulation system is given. In this joint simulation system the digital simulation interfaces are implemented by A/D conversion channels and controlled injection current sources, and the physical simulation interfaces are implemented by amplifying circuits with the structure of DC coupling based back-to-back converters. The results of experiments show that the proposed joint simulation technology is feasible.
