摘要
针对传统TCR控制算法导致隔离变压器磁通饱和的情况,提出一种基于简单逻辑与传统PI控制相结合的控制策略,在不影响原有控制算法效率的基础上对其进行相应的改进,以提高TCR的性能。在此基础上提出控制策略的软件实现,并利用PSCAD对其性能进行仿真,结果显示此算法能显著改善TCR对其隔离变压器性能的影响。
Contraposing the traditional control algorithms for TCR,which may bring on the magnetic flux saturation of isolated transformer,a scheme is proposed for improving the performance of TCR without impacting on the efficiency of primary ones,which is based on the combination of simple logic and traditional PI control method.And then,the realization is put forward based on MCU.The simulation results given by PSCAD demonstrate that the controller may improve dynamic performance of isolated transformer affected by TCR significantly.
