Book Fuzzy Logic Concepts in Power System Stability

Download or read book Fuzzy Logic Concepts in Power System Stability written by Neeraj Gupta and published by LAP Lambert Academic Publishing. This book was released on 2010-07-01 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of power system stabilizers has become very common in operation of large electric power systems.The conventional PSS which uses lead- lag compensation, where gain settings designed for specific operating conditions, is giving poor performance under different loading conditions. Therefore, it is very difficult to design a stabilizer that could present good performance in all operating points of electric power systems. In an attempt to cover a wide range of operating conditions, Fuzzy logic control has been suggested as a possible solution to overcome this problem, thereby using linguist information and avoiding a complex system mathematical model, while giving good performance under different operating conditions. Simulink Block Design and Matlab-7.5 is utilized in implementing the study. The performance of the system with fuzzy logic based power system stabilizer is compared with the system having conventional power system stabilizer and system without power system stabilizer.

Book Improvement of Dynamic Power System Stability by Installing Unified Power Flow Controller UPFC Based on Fuzzy Logic Power System Stabilizer FLPSS

Download or read book Improvement of Dynamic Power System Stability by Installing Unified Power Flow Controller UPFC Based on Fuzzy Logic Power System Stabilizer FLPSS written by Arizadayana Zahalan and published by . This book was released on 2014 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last two decade, the demand of electrical power increased tremendously and power system have been operated under much more stressed condition hence may lead to unstable power system. On the other hand, low frequency oscillation due to interconnection between remotely located power system may as well affect the system stability. Thus, to improve dynamic power system stability the research proposed the installation of Unified Power Flow Controller (UPFC) which is the most versatile Flexible AC Transmission System (FACTS) device in single machine infinite bus (SMIB) based on fuzzy logic power system stabilizer (FLPSS). In the proposed system, the parameters for the power system before and after the installation of UPFC is derived referring to the Phillips-Heffron SMIB model. After the mathematical process, the value of all the parameters is obtained using Matlab m-file listing program. Based on the parameter value, the block diagram for the power system before and after the installation of UPFC is formed using Matlab Simulink. Power system stabilizer is then added to the conventional power system model while FLPSS is added to UPFC excitation control. In this study, damping controller m_E and m_B of UPFC is used. After given small disturbances to both power system, the ability of both power system to damp oscillation is monitored by investigating the changes of rotor angle, change of rotor speed and change of electrical power. The result showed that that fuzzy logic controller is able to decrease the amplitude of low frequency oscillation and increases damping rate successfully. Comparing between power system model installed with UPFC based on FLPSS and conventional power system indicates that the proposed FLPSS has less settling time and less overshoot. When electrical power is increased at 0.1 pu, using damping controller m_E, rotor angle overshoot is decreased at 84.63% and settling time decreased at 80.32%. Rotor speed overshoot decreased at 63.28% whereas the settling time is reduced at 61.97%. The electrical power also shows a significant reduce in overshoot by 16.31% while the settling time is reduced by 61.80%. For m_B, rotor angle overshoot is decreased at 82.87% and settling time decreased at 82.61%. The rotor speed experienced a decrease of 57.55% in overshoot whereas the settling time is reduced at 74.24%. For electrical power, settling time is reduced by 60.24%. When electrical power is decreased at 0.1 pu, using damping controller m_E, rotor angle overshoot decreased at 84.61% and settling time decreased at 82.00%. Rotor speed overshoot decreased at 63.29% whereas the settling time is reduced at 63.83%. The electrical power also shows a significant reduce in overshoot by 16.31% while the settling time is reduced by 61.61%. For m_B, rotor angle overshoot is decreased at 82.87% and settling time decreased at 83.03%. The rotor speed experienced a decrease of 57.51% in overshoot whereas the settling time is reduced at 74.24%. For electrical power, settling time is reduced by 59.94%.This thesis focuses on analyzing different nonlinear algorithms to capture the emotional information present in two bio-signals namely Electrocardiogram (ECG) and Electromyogram (EMG). Emotion recognition is one of the emerging research areas in human computer interaction (HCI) and has been widely used in applications such as e-learning, smart classrooms, medical applications for patients with autism, Parkinson’s disease etc., Five basic emotional states (happiness, sadness, fear, surprise and disgust) and neutral signal was induced in sixty subjects by means of audio-visual stimuli.

Book Artificial Intelligence in Power System Stabilizer

Download or read book Artificial Intelligence in Power System Stabilizer written by Neeraj Gupta and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conventional power plants of 1950s were equipped with continuously acting automatic voltage regulators to improve the transient stability of system. The high gain of these voltage regulators has a destabilizing effect on power system. The power oscillations of small magnitude and high frequency, which often persisted in power system, present the limitation to the amount of power transmitted within the system. Improved performance has been achieved by adding damping to the system by employing power system stabilizers (PSS). Conventionally a lead- lag PSS was used to achieve this objective but has certain demerits like sluggish response etc. The use of Artificial intelligence has gain momentum now days in power system. This book gives the overview of various artificial intelligence techniques used in PSS till now and a case study based on fuzzy logic based PSS, its performance for a grid connected synchronous generator, and finally the effect of type of membership functions on PSS. This is my second book in this area. Its a perfect book for the students, researchers and industry related experts to explore the possibility of AI techniques in power system stability problems.
