摘要:

在对常规电阻型超导限流器失超机理及基本模型简要分析的基础上,为减缓常规电阻型超导限流器存在的固有缺陷,提出了基于多个电阻型超导限流器的故障限流运行模式组合。在PSCAD/EMTDC仿真平台上搭建了电阻型超导限流器的自定义模型,并基于南澳160 kV多端柔性直流输电系统,研究了系统故障时超导限流器对电网的影响,表明了自定义模型的正确性与必要性。分析了在同一限流效果下与常规电阻型超导限流器相比的优缺点,为柔性直流输电系统超导限流器选择提供了理论依据。

Abstract:

Based on a brief analysis of the quenching mechanism and basic model of conventional resistance superconducting fault current limiters,and in order to alleviate the inherent defects of conventional resistance superconducting fault current limiters,a combination of fault current limiting operation modes based on multiple resistance superconducting fault current limiters was proposed.A custom model of resistance superconducting fault current limiter was built on the PSCAD/EMTDC simulation platform,and based on the Nan’ao 160 kV multi-terminal flexible DC transmission system,the influence of the superconducting fault current limiter on the power system during system failure was preliminarily studied to show the correctness and necessity of the custom model.The advantages and disadvantages of conventional resistance superconducting fault current limiters was compared to the mode combination under the same current limiting effect,which provides a theoretical basis for the selection of superconducting fault current limiters in flexible DC transmission systems.

Key words: superconducting fault current limiter, fault current limiting, short-circuit current, model, mode combination
