This paper introduces the research status of controllable reactor by consulting literatures, analyzes the regulation principle of controllable reactor and points out the realization mode of controllable compensation capacity of reactor. Based on this, Aiming at the problems of various structures and different names of the existing reactors, more than 20 kinds of controllable reactors are classified from the perspective of the working principle of controllable reactors. The characteristics of each type of controllable reactors are summarized. And a comparative analysis of controllable reactors is made from the control accuracy, response speed, harmonic content and other aspects. Finally, the development of controllable reactor is prospected. The results show that, according to the regulation principle of controllable reactor, controllable reactor can be divided into two types: mechanical controllable reactor and magnetic adjustable controllable reactor. Magnetic controllable reactor has obvious advantages and good practical value;besides, the DC magnetic controllable reactor has the characteristics of small capacity control, which is widely used. The future development of controllable reactor can focus on six aspects: magnetization characteristics, intelligent protection and control, controllable reactor-transformer magnetic integrated equipment, et al.
