高温超导故障限流器的数学模型及其数字仿真

Model and Simulation Of a High T_c Superconducting Fault Current Limiter

本文分析并建立了饱和电抗器型高温超导限流器的仿真模型，利用电磁暂态程序ＥＭＴＰ对该新型限流器的限流效果进行了数字仿真。通过与传统的线性限流电抗器的对比分析，证明新型限流器能有效地解决减小正常运行电压损失与增大限制故障电流能力之间的矛盾。

A model of a high To Superconducting Fault Current Limiter, which has a nonlinear inductance,has been built based on its analysis in this paper. Its Limiting fault current effect is simulated by EMTP programe. Comparing with traditional linear inductance,the results show that the new limitercan decrease effectively voltege drops under normal operation,and limits fault currents during system fault condition.
