This paper presents an effective method for detection and classification of Power Quality Events (PQE), based on Fast Fourier Transformation (FFT) event identification Artificial Neural Network (ANN) technique classifying these events. Firstly, synthetic data such as pure sine a reference, voltage sag, swell, flicker, transient, with harmonics are created in MATLAB TS EN 50160 standard. Databas...

Electrical power quality is one of the main elements in generation systems. At same time, it most significant challenges regarding stability and reliability. Due to different switching devices this type architecture, kinds generators as well non-linear loads are used for industrial processes. A result need classify analyze Power Quality Disturbance (PQD) prevent degradation system reliability a...

This paper proposes a novel pixel circuit and driving scheme that adopts low-temperature polycrystalline silicon oxide thin-film transistors (LTPO TFTs) for mobile devices using active-matrix organic light-emitting diode (AMOLED) displays. The proposed provide uniform luminance render flicker invisible at variable refresh rates (VRRs) from 1 to 120 Hz. Using the with extended compensation time ...

a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

Power quality becomes one of the significant contemplations in power system. It has become particularly with presentation advanced devices. These high-level devices are sensitive to nature supply. The refers voltage, current, and frequency at evaluated value. If any variation occurred these quantities standard rating is considered as problem. issues like loss sine, voltage sag, swell, short int...

This paper expounds the influence of decentralized wind power on characteristics distribution network. Through analysis, it can be concluded that after installing an appropriate amount power, voltage level load bus improved. The flow will changed, and network loss grid reduced. has also brought about negative impacts, such as flicker harmonics, impact scope direction protection relay protection...

An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...
