| 摘要：引入SPWM控制下的开关函数概念，提出了基于SPWM控制的UPFC开关函数数学模型。此模型反映了UPFC装置内部的开关特性和运行机理，考虑了串、并联变压器的不同变比及三相电网电压的不平衡，较原有的输出模型更具一般性。 | |

Abstract: This paper introduces the concept of SWITCHING function and the SWITCHING function mathematical model of UPFC based on SPWM control. The model reflects the INTERNAL SWITCHING character and the physical course of UPFC and has more generality than the OUTPUT model. | |
