摘　　要：通过分析统一潮流控制器(UPFC)的基本结构,及交叉解耦控制的基本原理,在一般的交叉解耦控制方案的基础上提出了一种有异于一般交叉解耦控制的方案,这种方案除了在并联侧引入以节点电压为基准的Park变换外,在串联侧也引入以系统电流为基准的Park变换,省去了原来控制结构中的一个交叉解耦控制环节,使得控制结构更简单直接、容易实现,在电力系统的设计开发中具有一定的实际意义。最后利用Matlab中的仿真软件包,通过仿真验证了该方案的可行性。With analyzing the basic structure of the unified power flow controller （UPFC） and the principles of the general decoupled control scheme, a different scheme on the foundation of the universal decoupled control scheme was proposed, Besides introducing Park transformation in the shunt circuit based on node voltage, it also introduced that in the series circuit based on system current, So that it eliminates a decoupled control link, and its decoupled control scheme becomes more simple and can be carried out more easily, which is of a definite practical significance in the design and development of power system. The simulation was taken in the Matlab software simulation platform, and the result verified the new scheme＇s feasibility.
