摘　　要：在关于统一潮流控制器(UPFC)抑制系统低频振荡研究的基础上,将阻尼转矩分析(DTA)方法扩展至包含UPFC的多机电力系统,依据稳定器的阻尼转矩产生、传递和分配的机理,提出了应用DTA指标指导UPFC最佳阻尼通道的选取,并通过四机两区域系统验证了DTA方法的合理性。鉴于UPFC多个阻尼通道可附加多个稳定器以抑制多个振荡模态,提出一种UPFC多个稳定器的协调设计方法,通过DTA指标选取UPFC多个阻尼通道,采用Hooke-Jeeves直接搜索法协调各阻尼系数,再应用相位补偿法设计稳定器参数。仿真结果验证了该方法能够有效抑制多模态(包括区间与区内)振荡。Based on the research of low-frequency oscillation damping by UPFC（Unitied Vower Flow uon- troller） ,DTA（Damping Torque Analysis） method is extended to the multi-machine power system with UPFC. According to the mechanism of damping torque generation,transmission and distribution of stabilizer,DTA index is adopted to select the best damping channel of UPFC. A four-generator two-area system is taken to verify its rationality. Since multiple stabilizers can be added to multiple damping channels of a UPFC for suppressing multiple oscillation modes,a method of coordinated design is proposed for the multiple stabi- lizers of a UPFC,which selects multiple damping channels of UPFC according to DTA index,applies Hooke- Jeeves method to coordinate the equivalent damping coefficients,and uses the phase compensation method to design the parameters of multiple stabilizers. Simulative result shows that,the proposed method can effec- tively damp multi-mode oscillations（including inter-area mode and local mode）.
