Research on Reactive Power Compensation Based on Magnetic Saturation Controllable Reactor

Abstract

With the improvement of the automation level of the power system and the development of power electronic equipment, the magnetic saturation controllable reactor will surely become indispensable reactive power compensation equipment. But there are few researches on it at home and abroad. In the power system with its superior performance the magnetic saturation controllable reactor studied in this article is a static dynamic reactive power compensation device, which mainly uses lagging inductive reactive power to offset the leading capacitive reactive power. In this paper, its structure and working principle are studied in detail, electromagnetic calculation and simulation analysis are carried out, and genetic algorithm is introduced to optimize it. From theory to practice, a thorough discussion is made to make up for the blank of this direction.

Bi-Directional Converter System for Light Load by Heterogeneous Combined Type Reactor

“…by motion or the light load. Thus, it is necessary to develop a topology that can reduce the current ripple factor in the light load motion for the converter installed in the DC power transmission network [6,7,8,9]. This paper proposes a new type of smoothing reactor using heterogeneous reactors with different magnetic flux saturation to construct a DC-DC converter with low current ripple under light load in a bidirectional DC-DC converter.…”

“…The converter for renewable energy generation and ESS installed in the DC power transmission network is mostly operated at all times; however, the time of participation in the power transmission of heavy load or higher is considerably shorter than the stand-by motion or the light load. Thus, it is necessary to develop a topology that can reduce the current ripple factor in the light load motion for the converter installed in the DC power transmission network [6][7][8][9]. This paper proposes a new type of smoothing reactor using heterogeneous reactors with different magnetic flux saturation to construct a DC-DC converter with low current ripple under light load in a bidirectional DC-DC converter.…”
