摘要
目前的磁阀式磁控电抗器磁阀的存在使得电抗器绕组匝数大大增加,为了克服这种缺陷,提出一种新型的磁控电抗器的模型,给出了该新型电抗器的电路拓扑结构、磁阀大小的选择原则,由该磁控电抗器的场路耦合方程对其进行了电流谐波分析,得到了其谐波电流表达式,同时通过建立该磁控电抗器的MATLAB仿真模型,并对该磁控电抗器的工作电流波形进行了仿真与验证.最后讨论了利用该新型磁控电抗器实现静止无功补偿的电路结构、相应的控制电路及控制流程.
In order to overcome the defects of the magnetic valve type controllable reactor such as more winding turns and higher copper loss currently,a novel magnetic controllable reactor is proposed in this paper.The circuit topology structure of the reacor and the selection principle of the magnetic valve size are given.The current harmonic analysis of the proposed magnetic controllable reactor is made,a MATLAB simulation model of the magnetic controllable reactor is established,and some simulation results are given in the paper.Finally,the circuit structure that realized static reactive power compensation are discussed.
