均衡电抗器是变抽头六相整流系统的关健器件。在对变抽头六相整流系统均衡电抗器电感取值进行详细理论分析的基础上,提出一种计算均衡电抗器临界电感简单而有效的方法,并通过仿真和实验证明了理论分析的正确性。根据该方法计算的临界电感值具有足够精度,能够满足工程需要。理论分析所得结论可用于均衡电抗器的参数选定,为变抽头均衡电抗器的设计提供了依据。

This paper provides a detailed theoretical analysis of the equilibrium reactorinductance critical value in a six-phase rectifier with tap-changer. A simple and effective method ispresented to calculate the critical value of the reactor. Simulation and experimental results verify the validity of the calculation approach. The calculated critical value is accurate enough to meet theengineering need. The parameter of the reactor must be larger than the critical value. On balance, the conclusions play an important role in the design of the equilibrium reactor.
