笔者针对变压器式可控电抗器(controllable reactor of transformer type,CRT)不同的控制绕组结构,将其分类为单控制绕组型、多控制绕组型、多并联支路型、控制绕组分级式。综述了CRT的研究历史与现状,并分析了各种CRT的结构特点、性能的优缺点,最后对CRT研究发展的前景进行了分析。
The controllable reactors of transformer type (CRTs) have different structures of control-winding. According to the control-winding structure, CRT is classified as single control-winding CRT, multi-control-winding CRT, multi-parallel branch CRT, and stepped control-winding CRT in this paper. The history and present situation of the research on CRT are reviewed. The features and performances of different kinds of CRT are analyzed and compared. Consequently, further research on CRT is prospected.
