摘要

如今，人们越来越关注现代电力系统的稳定性改善，特别是由于将分布式发电纳入电网。电力系统的稳定性是提高电力系统效率的主要挑战之一。电力系统稳定器(PSS)是提高电力系统稳定性和可靠性的一种经济有效的控制器。本文将励磁系统与PSS相结合，提高了IEEE 9总线系统的暂态稳定性。考虑了相对功率角对暂态稳定性的影响。仿真结果表明，现有系统存在振荡现象。而与励磁器ST1A和PSS1A集成后，峰值功率角从132.1°减小到103.7°，稳定时间为5.53 s。此外，当PSS连接到ST1A时，速度偏差得到改善。

Transient Stability Improvement of Power System using Power System Stabilizer Integrated with Excitation System

Nowadays, there is an increased concern for stability improvement in modern electrical systems, especially due to the use of distributed generation into the grids. Stability of power system is one of the main challenges to improve the power system efficiency. A Power System Stabilizer (PSS) is a cost-effective controller and efficient device to increase the stability and reliability of power systems. In this paper, the transient stability of IEEE 9-bus system is improved with the integration of excitation system and PSS. The relative power angle is considered to evaluate the transient stability. The simulation results show that the existing system has oscillated. However, when the system is integrated with the exciter ST1A and PSS1A, the peak power angle decreases from 132.1° to 103.7°, and the settling time is 5.53 s. Additionally, the speed deviation is improved when PSS connected to ST1A.
