饱和铁芯型超导可控电抗器(saturated core superconducting controllable reactor)是一种超导电力技术研发的新型可控电抗器。与传统电抗器相比,具有体积小、重量轻、效率高、阻燃等优势,在超高压输电系统中对调节电压起着重要作用。通过分析饱和铁芯型超导可控电抗器的原理,利用PSCAD搭建云南电网德宏至砚山500kV输电线路模型,结合实际线路的潮流分布,在线路首端博尚和线路末端砚山投入超导可控电抗器进行仿真分析,比较在不同运行方式下投入可控电抗器前后对两地电压的调节效果,为饱和铁芯型超导可控电抗器在云南500kV输电系统中的应用提供参考。

Saturated core superconducting controllable reactor is a new type controllable reactor of a superconducting power technology research and development, compared with the traditional reactor has the advantages of small volume, light weight, high efficiency, flame retardant and other advantages, in EHV power transmission system plays an important role in regulating voltage. Through analyzing the principle of saturated core superconducting controllable reactor, using PSCAD to build the Yunnan Dehong power grid to Yanshan 500kV transmission line model, combined with the actual power flow, simulation analysis was car- ried out in one end of the transmission line and the end of the line on Yanshan into superconductive controllable reactor, the com- parison of input regulating effect on both before and after the voltage controllable reactor under different operation modes was con- ducted. It provides reference for the application of saturated core superconducting controllable reactor in Yunnan 500kV in trans- mission system.
