摘要：To guarantee the secure and reliable operations of power systems through the rapid damping of low-frequency electromechanical oscillations (LFEOs) is the ultimate objective of this study. This paper presents a coordination of a flexible AC transmission system (FACTS) device and power system stabilizer (PSS) to meet this objective, and deals with the design of a damping controller based on a thyristor-controlled phase shifter (TCPS) and a PSS. The proposed design is incorporated in the framework of a single-machine infinite-bus (SMIB) power system. The effectiveness of the proposed design in damping power system oscillations is explored through eigenvalue analysis, time-domain simulations and damping torque contribution. A comparative study on different control schemes, such as with an SMIB including a PSS and an SMIB including a TCPS-based damping controller is also carried out. The obtained results prove the superior performance of the proposed design in improving the stability of the given power system. All the digital simulations are performed using MATLAB/ SIMULINK.
