应用等面积准则，建立了分析静止无功补偿器（SVC）对电力系统阻尼增强作用的理论。讨论了SVC对电力系统的影响、如何控制SVC以提高系统阻尼以及SVC无功功率连续控制和不连续控制以实现最大阻尼改善的区别等基本问题。由输电线路上的功率偏差确定离散点处的不连续SVC无功功率输出。将该方法应用于单机系统以增加摆动振荡阻尼和应用于四机系统以增加区域间振荡模式阻尼的时域仿真表明，该理论和方法可应用于解决实际电力系统阻尼问题。>
A theory for analyzing power system damping enhancement by application of static VAr compensators (SVCs) has been developed using the equal area criterion. Some fundamental issues, such as the effect of SVCs on a power system, how to control an SVC to improve system damping, and the differences between continuous and discontinuous control of SVC reactive power to achieve the maximum damping improvement, are discussed. A discontinuous SVC reactive power output at discrete points is determined from the power deviation on a transmission line. Time-domain simulations of the application of this approach to a one-machine system to increase swing oscillation damping and to a four-machine system to increase the damping of an interarea oscillation mode demonstrate that the theory and method can be applied to solve practical power system damping problems. >
