| Nowadays,users have higher requirements for system dynamic voltage stability,and reactive power compensation technology is of great significance to improve power quality.As a reactive power compensation device,saturation controllable reactor can continuously adjust inductance by changing the control current.In this paper,a new orthogonal magnetic saturation controllable reactor is studied.Based on the theory of material magnetization,the working principle of the reactor is described in detail.The structure of the reactor is designed and the operating parameters of the reactor under different working conditions are simulated by finite element analysis software.The prototype is made and verified by experiments.Based on the comparison of different types of controllable reactor at home and abroad,the advantages and application scope of magnetic saturation contrable reactor are obtained.Secondly,the basic concepts of magnetic field and magnetization curve are introduced.The basic structure and working principle of the new orthogonal magnetic saturation controllable reactor are analyzed in detail.The operational characteristics of the designed reactor are deduced in detail by using the equivalent magnetic circuit method.Referring to the existing structural design data of transformer and magnetron reactor,the structure of the new orthogonal magnetic saturation controllable reactor is designed,and the reactor model is built by Ansoft finite element analysis software.The internal magnetic field distribution,power winding inductance conversion and current harmonic components of the designed reactor are solved in detail by simulation,and the simulation results are given.A prototype of magnetically saturable adjustable reactor is manufactured.Experiments are designed to measure the working parameters.The experimental results are close to the simulation data,which shows that the design of the reactor is reasonable.The experimental analysis shows that the designed magnetically saturated adjustable reactor has the characteristics of continuous smooth and adjustable inductance of the power loop,no magnetic coupling relationship between the power loop and the control loop,and low harmonic content of the current in the power loop. |
