摘要:
星形自耦变压器是12脉波整流器中常用的移相变压器,该变压器各绕组之间交互联结,在仿真软件中没有对应的仿真模型。为在仿真软件中模拟星形自耦变压器对1 2脉波整流器性能的影响,应用相分量法建立了该变压器的全解耦模型。通过分析星形自耦变压器的耦合电路,建立了描述支路电压、支路电流、节点电压、节点电流之间关系的过渡矩阵,进一步获得可以描述星形联结自耦变压器绕组联结结构、电气参数等信息的节点导纳矩阵,并应用该矩阵建立了描述星形自耦变压器的全解耦模型。该模型具有物理意义明确、易于实现等优点。仿真和实验结果表明,该模型可有效模拟星形自耦变压器。

Abstract:
Star-connected autotransformer is commonly used to be the phase-sliift transformer in the 12- pulse rectifier. The windings of the star-connected autotransformer are interconnected so that there is no simulation mode in the software. In order to simulate the effect of star-connected autotransformer on 12- pulse rectifier,the decoupled model of tlie autotransformer was set up using the phase-coordinate metliod. Via analyzing the coupling circuit of the autotransformer, the transition matrixes which are used to de-scribe the relations among the branch voltage , branch current , node voltage and node current and furthermore,the node admittance matrix which contains the information of winding connection and e-lectrical parameters was derived. Using the node admittance matrix,the decoupled model was built. The decoupled model is easy to realize and has clear physical meaning. Simulation and experimen indicate that the decoupled model of star-connected autotransformer is effective.
