摘　　要：为深入分析和了解磁位计在电力系统故障状态下的工作特性 ,叙述了用 MATLAB对磁位计的暂态响应过程进行仿真计算的方法和实验结果。仿真计算结果表明 ,磁位计的暂态响应对于一次信号的波形具有良好的跟随作用 ,能很好地反映原方信号的各种频率分量的变化情况 ,通过理论计算给出了磁位计最佳暂态响应的设计参数及其仿真响应曲线。In order to analyze and understand the working processes of the magnetic potentiometer in the fault states of electric power system thoroughly, the simulation calculations of the transient response to the magnetic potentiometer are carried out with MATLAB. These simulations are based on taking the most serious fault state into account and the calculation results show that the magnetic potentiometer has a better tracing to the original signals in all aspects, including different frequencies and different amplitudes. To obtain the best transient response characteristics of the magnetic potentiometer, some theoretical analyses are further carried on, and special consideration in materials, technologies and signal processing. Thus the best parameters and the best simulation transient response curves are presented. Moreover, a simulation conclusion can be drawn that the magnetic potentiometer can totally satisfy the practical use as current transformer.
