A continuous and reliable electrical energy supply is the objective of any power system operation. Electricity is the driving force behind industry and subsequently economy. There are various types of faults appear in power system. Faults can appear due to bad weather conditions, equipment damage, equipment failure, environment changes and many other reasons. Any occurrence of a fault should be detected and cleared by the protective relaying devices. Fast and accurate fault location is a key task for accelerating system restoration, reducing outage times, and hence, improving system reliability. The aim of this project is to develop a two stage fault location algorithm that can determine the distance to the fault. The proposed two-stage fault-location algorithm is applicable for transposed and untransposed transmission lines and is independent of the fault resistance and source impedances. The synchronization angle is determined by using Newton-Raphson method. The maximum error reached from this algorithm is less than: 0.18% for LG faults, 0.20% for LL faults, and 0.26% for LLG faults.

This paper deals with modelling and simulation of Single phase AC-DC Bridgeless Continuous Conduction Mode (CCM) with Single Ended Primary Inductance Converter (SEPIC) for Power Factor Correction (PFC) rectifier. The topology is improved by the absence of an input diode bridge and the presence of only two semiconductor switches in the current flowing path during each switching cycle which results in lesser conduction losses and improved thermal management compared to the conventional SEPIC converters. By implementing the improved topology in CCM it ensures almost unity power factor in a simple and effective manner. The CCM operation reduces the complexity of the control circuitry. An operating principle and a detailed analysis of the proposed converter are presented. It is shown that the efficiency of the SEPIC Converter can be significantly improved. Performance Comparisons between the improved and conventional SEPIC PFC rectifier are carried out using MATLAB software and result is presented.

The proposed photovoltaic Micro Inverter is based on three port fly back with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the transformers leakage energy. A diode is involved to prevent the reverse current from power decoupling capacitor to PV panel.

This paper presents modeling and simulation of a single phase simplified eleven-level inverter (SELI). Multilevel inverter offers high power capability. Its performance is highly superior to that of conventional two-level inverter due to reduced harmonic distortion, lower electromagnetic interference and higher dc link voltage. The inverter is capable of producing eleven levels of output voltages (Vdc, 4Vdc/5,3vdc/5,2Vdc/5, Vdc/5, 0,-Vdc/5,-2Vdc/5, -3Vdc/5,-4Vdc/5,-Vdc) from the DC supply voltage. Theoretical predictions are validated using MATLAB Simulink tool box.

A three-input hybrid system for solar car is designed in this project. It consists of one unidirectional input power port and two bidirectional power ports with a storage element. Depending on utilization state of the battery, three different power operation modes are defined for the converter. Battery charging in the system is carried out from the amorphous solar panel mounted on the body and a solar energy harvesting charging station. Since the solar energy is directly given to the DC load, the efficiency of the system will improve. The capacitor which is connected to the lead acid battery will charge at off peak hours and discharge during the acceleration time of the car. In this proposed system energy wasted in the brakes are also recovered and used to charge the lead acid battery. Hence competent Hybrid Electric Vehicle was developed by using super capacitor and regenerative braking scheme.

Deregulated power industries increase the efficiency of electricity production, distribution and more reliable electricity at low prices. In a deregulated environment, utilities are not required to meet the total load demand. Generation companies (GENCOs) schedule their generators with an objective to maximize their own profit rather than compromising on social benefit. Profit Unit commitment (PBUC) in deregulated power system has a different objective than that of traditional unit commitment.. This paper presents a hybrid model between Lagrangian Relaxation (LR) and an artificial bee colony (ABC) algorithm, to solve the profit-based unit commitment problem. The proposed approach is investigated on ten units 24 hour test system and numerical results are tabulated. Simulation results shows that this approach effectively maximize the GENCO's profit when compared with existing methods.

This paper presents a control scheme of single phase to three phase converters for low power three phase induction motor drives, with reduced number of switching devices. Here a single phase half-bridge PWM rectifier and two-leg inverter are used with the same function that are all given by conventional one such as sinusoidal input current, unity power factor, bidirectional power flow, dc-link voltage control. Hence the number of switching devices is reduced from ten to six. A current controller is introduced for two-leg inverter. In addition, the source voltage sensor elimination technique is presented which makes the system cheaper. The effectiveness of the proposed control scheme is verified by experimental results for the V/ f control of 3-HP induction motor drives with FPGA based controller.

Multi-phase voltage source inverters are dominantly used to supply the multi-phase drives which are used for high power applications. Multi-phase induction motor drive possess several advantages over conventional three-phase drive, such as reduced current per phase, increased power in the same frame and high torque frequency etc., The technique discussed in this paper is easy to implement and avoid complicated controlling algorithm adapted in SVPWM technique. The generalized switching technique is proposed in this paper. A generalized algorithm suitable for odd number of phases is developed in Matlab/Simulink environment and discussed in detail. The performance of the 5, 7 and 9-phase VSI is studied with the above said switching method. The VSI fed multi-phase drive is analyzed. The simulation results are presented for different modulation indices and compare the performance of the drives are presented.
