一种带有逆变器控制的新型可调电抗器
New-style Adjustable Reactor Based on Inverter Control
摘要
Abstract
In allusion to problems of discontinuously adjustable reactance value, severe pollution of harmonic, slow response and poor stability of the adjustable reactor, this paper presents a kind of new-style adjustable reactor scheme based on voltage typed inverter and air gap transformer control which connects the new-style adjustable reactor with the power system in series and realize continuous and stepless control of transformer original side equivalent impedance by controlling amplitude and phase of secondary winding voltage of the transformer. It takes series adjustable reactor with resistance-inductance load for an example, makes deduction and calculation according to Routh criterion and finally obtains condition for system stable operation. It carries out simulation on the system based on power simulation (PSIM) software and discovers that impedance of this adjustable reactor is continuously stepless adjustable without saturation or any noises and harmonic under the situation of satisfying stable operational conditions. Theoretical analysis and simulation results both verify effectiveness of this new-style adjustable reactor and stability condition.关键词
