摘要
本文以改进桥路型高温超导限流器模型为代表,分析其设置在发电机端口时对电力系统暂态稳定性影响的研究。文章分析了改进桥路型高温超导限流器的工作原理,以单机无穷大系统为例,通过数学模型的计算分析研究其电阻、电抗参数值不同时对电力系统暂态稳定性的影响;并在MATLAB/Simulink的软件仿真平台上搭建仿真模型,分别仿真阻抗型高温超导限流器的电阻、电抗值不同、故障切除时间不同、短路故障类型不同时的发电机转子摇摆曲线图。从理论分析和仿真结果说明:若只考虑其对电力系统暂态稳定性的影响,应选择电阻值较大,电抗值较小的阻抗型高温超导限流器安装在发电机端口,能有效地减小发电机转子的最大摇摆角,延长故障极限切除时间,对电力系统的暂态稳定性产生积极的影响。
In this paper,the influence of the model of the improved bridge type high temperature superconducting fault current limiter is studied on the transient stability of power system.This paper analyzes the working principle of the improved bridge type high temperature superconducting fault.Taking a single machine infinite bus system as an example to study the influence of the resistance and reactance parameters on the transient stability of power system by the mathematical model.And the simulation model is built in Matlab/Simulink software simulation platform,respectively,simulation impedance type high temperature superconducting fault current limiter is resistance and reactance value different,fault clearing time different,type of faults of the generator rotor swing curve.From the theoretical analysis and simulation results show that：if only takes into account the impact on power system transient stability should be choosing the resistance value larger reactance value smaller impedance type high temperature superconducting fault flow device is installed in the generator port,can effectively reduce the generator rotor maximum swing angle,extend long fault critical clearing time,has a positive impact on the transient stability of power system.
