The performance and transient stabilizing using a unified power flow controller (UPFC) anticipated for a grid consisting of parallel connected two number of three-phase transmission lines is presented in this paper. The interruption that happened in absence of UPFC connected to three phase line increases the impedance of the transmission line and consequently reduces the flow of active power. The volume of active power flowing through the grid can be controlled by installing UPFC on the grid. The conditions for transient stability are suggested by the transient model and UPFC interconnected power grid. The complete dynamic control is modeled by the active and reactive power waves developed during transient events. A series of simulations are presented in this paper to show the effectiveness and correctness of the methodology applied for transient stability.

本文介绍了使用统一潮流控制器 (UPFC) 对由并联连接的两条三相输电线路组成的电网的性能和暂态稳定。在没有连接到三相线的 UPFC 的情况下发生的中断增加了传输线的阻抗，从而减少了有功功率的流动。通过在电网上安装 UPFC 可以控制流经电网的有功功率量。暂态模型和 UPFC 互联电网建议了暂态稳定的条件。完整的动态控制由瞬态事件期间产生的有功和无功功率波建模。
