摘　　要：国内首台国产110kV/30MVA磁阀式并联高压可控电抗器已在湖南怀化电业局220kV田家变投入运行,为此,分析了田家变电站220kV侧母线电压过高、110kV侧母线电压波动过大的原因,提出在110kV母线加装并联可控电抗器的解决方案,并研制了国内首台110kV磁阀式可控电抗器工业样机,开发了基于Intel80C196KC单片机的控制装置与保护装置。试验和样机运行数据表明:该电抗器谐波含量低,损耗小,控制装置可靠,解决了高压侧电压过高、中压侧电压波动大的难题,提高了系统供电质量。The first 110 kV/30 MVA shunt magnetically controllable reactor（MCR）, made in China, has been used successfully in Tianjia 220 kV substation of Haihua, Hu＇nan province. We analyzed the reasons of excessively high voltage of 220 kV bus and big voltage fluctuation of 110 kV bus in the same time,and proposed to install a shunt controllable reactor on the 110 kV bus. And the first 110 kV/30 MVA MCR of China was made. Accordingly, the controller based on microcontroller of Intel 80C196KC was designed. Moreover, protection system of the reactor was designed. The controller can exchange data from the substation automation system（SAS}. The data from testing and using prove that the reactor has low harmonics and low power loss. The controller can work reliably, and solves the problems of over-voltage of 220 kV bus and big voltage fluctuation of 110 kV bus in the substation, improving the quality of power supply greatly.
