Determination of Fault Location and Type in Distribution Systems using Clark Transformation and Neural Network Mohammad Sarvi; S. M. Torabi
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 2: August 2012
Publisher : Institute of Advanced Engineering and Science

In this paper, an accurate method for determination of fault location and fault type in power distribution systems by neural network is proposed. This method uses neural network to classify and locate normal and composite types of faults as phase to earth, two phases to earth, phase to phase. Also this method can distinguish three phase short circuit from normal network position. In the presented method, neural network is trained by αβ space vector parameters. These parameters are obtained using clarke transformation. Simulation results are presented in the MATLAB software. Two neural networks (MLP and RBF) are investigated and their results are compared with each other. The accuracy and benefit of the proposed method for determination of fault type and location in distribution power systems has been shown in simulation results.

Design and Development of Power Electronic Controller for Grid-connected PV Array T. Shanthi
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 2: August 2012
Publisher : Institute of Advanced Engineering and Science

Design and simulation of a simple power electronic interface for grid-connected PV array has been proposed using boost converter and line-commutated inverter with maximum power point tracking (MPPT) controller. The output of PV array varies with irradiation, and hence the duty cycle of the PI controller is adjusted automatically to supply a constant DC voltage to the inverter circuit, the output of which is directly connected to the grid. The MPPT controller extracts maximum power from the solar array and feeds it to the single-phase utility grid. The proposed scheme has been modeled in the MATLAB 7.1 software and the complete system has been simulated for open loop and closed loop configurations. The active power fed to the grid is taken for different firing angles in open loop mode and the firing angle for maximum power has been determined. This is compared with the firing angle obtained from the closed loop mode and found that both results agree with each other.

Impact of Thyristor Controlled Series Capacitor Insertion on Short-circuit Calculation in Presence Phase to Earth Fault Mohamed Zellagui; Abdelaziz Chaghi
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 2: August 2012
Publisher : Institute of Advanced Engineering and Science

This research paper presents a study on phase to earth fault short-circuit calculation with fault resistance on a single transmission line 400 kV in eastern Algerian transmission networks at Algerian Company of Electricity and Gas (Sonelgaz Group) compensated by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Capacitor (TCSC) installed in midline. The facts are used for controlling transmission voltage, power flow, reactive power, and damping of power system oscillations at high power transfer levels. The direct impacts of TCSC insertion on the total impedance, active power and reactive power a electrical transmission line and also parameters of short-circuit : symmetrical currents, line currents, symmetrical voltages and line voltages are carried out. More the effects of injected voltage by TCSC for three case studies are presented.

Dynamic Modeling of Autonomous Wind–diesel system with Fixed-speed Wind Turbine Najafi Hamid Reza; Dastyar Farshad
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 2: August 2012
Publisher : Institute of Advanced Engineering and Science

Wind turbines have often connected to small power systems, operating in parallel to diesel generators, as is typically the case in autonomous wind–diesel installations or small island systems with high wind potential. Hence, the modeling and analysis of the dynamic behavior of wind–diesel power systems in presence of wind power will be important. In this paper, the system under study is modeled by a set of dynamic and algebraic equations (DAE). Dynamic behavior of a wind-diesel system is investigated by the proposed dynamic model. Wind-diesel system consists of wind turbines that are connected to synchronous diesel generator via short transmission line with local load. Dynamic stability of autonomous wind–diesel systems are discussed with emphasis on the eigenvalue analysis and the effective parameters on system stability. In this regards, saddle node bifurcation and hopf bifurcation are also investigated.

Transmission Loss Allocation Based on Lines Current Flow Rahmat Aazami; Ali mansori; NosratAllah Mohammad Baigi; Amin Omidian; Ehsan Mohammadian
International Journal of Applied Power Engineering (IJAPE) Vol 1, No 2: August 2012
Publisher : Institute of Advanced Engineering and Science

In this paper, the transmission loss allocation problem has been studied and a new method for loss allocation in pool electricity markets has been proposed. To do that, at first using a transmission line loss equations respect to bus injected currents, the share of each bus from the mentioned transmission line losses has been determined. Then, this method has been applied to the total network transmission lines and the share of each bus from the total losses has been acquired. The proposed method is based on the main network relations and no any simplifying suppose has been used. Finally, the proposed method is studied on a typical network.
