摘要

在电力系统中保持与电网的同步，保证向用户提供高质量的电力。由此产生了影响输电线路潮流和输电效率的稳定性问题。快速发展的电力电子领域引入了能够轻松解决不稳定问题的FACTS器件。统一潮流控制器(UPFC)是最新一代的FACTS器件，它可以控制线路阻抗、终端电压、电压角等参数，进而控制互联系统之间机电振荡的阻尼，以保证系统的安全运行，并提高系统的稳定性。本文主要研究了采用MATLAB软件将带传统POD控制器的UPFC和带PI控制器的UPFC置于两机系统之间，实现对电压的支撑和对振荡的抑制。

Power oscillation damping of two machine system

To maintain synchronism with grid in power system for quality power delivered to consumer purpose. Due to this stability problem arises which affects the power flow and transmission efficiency on the transmission line. A rapid growth of power electronics area which introduces the FACTS devices that is able to solve the instabilities problem easily. The Unified Power Flow Controller (UPFC) is a latest generation of FACTS device which can control the parameters of line impedance, terminal voltages, voltage angles and then damping of electromechanical oscillations between interconnected systems for secure operation and also improve system stability. This paper focuses on the UPFC with conventional POD controller and UPFC with PI controller are placed between two machine system inorder to support voltage and damp the oscillation using MATLAB.
