摘　　要：在使用大功率设备越来越频繁的现代,移相变压器(PST)的使用越来越多。但移相变压器实现移相功能时总会存在一些误差,对系统的稳定性造成一定的影响。为此,使用Simulink仿真先对PST进行原理层次的仿真,然后使用整流模块进行多模块的串并联来检测模块输出数据进行分析。通过仿真移相角误差在不同情况下的数据分析,得出模块输出的电流、电压和功率受到移相角误差的影响,出现功率输出不平均情况。In modern times where high-power devices are being used more frequently,the use of Phase-Shifting Transformers(PST)is also increasing.However,there will always be some errors when implementing the phase-shifting function of the phase-shifting transformer,which will have a certain impact on the stability of the system.To this end,Simulink simulation is used to first simulate the principle level of PST,and then rectifier modules are used for multi module series parallel connection to detect module output data for analysis.By simulating the data analysis of phase shift angle error under different conditions,it is found that the current,voltage,and power output of the module are affected by phase shift angle error,resulting in uneven power output.
