Stabiliser Fault Emergency Control using Reconfiguration to Preserve Power System Stability

Response Based Emergency Control System for Power System Transient Stability

A transient stability control system for the electric power system composed of a prediction method and a control method is proposed based on trajectory information. This system, which is independent of system parameters and models, can detect the transient stability of the electric power system quickly and provide the control law when the system is unstable. Firstly, system instability is detec...

fault location in power distribution networks using matching algorithm

چکیده رساله/پایان نامه : تاکنون روش‏های متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روش‏ها در شبکه توزیع به دلایلی همچون وجود انشعاب‏های متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تک‏فاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...

Power System Transient Stability Preventive and Emergency Control

C. R. Fuerte-Esquivel Universidad Michoacana de San Nicolás de Hidalgo, Morelia, Mexico Abstract A general approach to real-time transient stability control is described, yielding various complementary techniques: pure preventive, open-loop emergency, and closed-loop emergency controls. Recent progress in terms of a global transient stability-constrained optimal power flow is presented, yieldin...

FACTS Control Parameters Identification for Enhancement of Power System Stability

The aim of this paper is to investigate a novel approach for output feedback damping controller design ofSTATCOM in order to enhance the damping of power system low frequency oscillations (LFO). The design ofoutput feedback controller is considered as an optimization problem according with the time domain-basedobjective function which is solved by a honey bee mating optimization algorithm (HBMO...
