Due to the increasing demands for electric energy and installation of distributed generation, the rising fault current poses a great threat to those existing power system components.
Superconducting controlled reactor (SCR), as a novel dynamic reactive compensation facility, has many advantages such as free harmonic, fast response, low losses and high voltage withstand [1]. However, due to SCR special structure and magnetic circuit, capacity gears of SCR designed by traditional methods are not accurate enough.
Virtual air gap controlled reactor (VGR) is an electrical device based on the working principle of the saturation in the iron cores [1]. The magnetic permeability of the iron cores in the VGR can be changed smoothly by regulating the direct current in the exciting windings. The higher the magnetic permeability of the iron cores, the greater the inductance of the VGR is, and vice versa. Since the advantage...
In order to flexibly compensate reactive power, it is necessary to develop a controllable reactor in long distance and ultrahigh voltage system. A leakage flux-controlled reactor (LFCR) is developed in this paper. The operation principles of LFCR are discussed in detail, and a 380 V single-phase LFCR prototype is developed. Relevant experiments have been done to test its performance. The results of...
