Abstract

Estimation of power system parameters for generation of reference signal is one of the most essential requirements for switching action of the converters. This paper explores the measurement of power system harmonic components with a newly developed Recursive Newton Type algorithm. In the developed algorithm, first the parameters will be updated using Jacobian and Co-variance matrices. Implementation of the co-variance matrix in the proposed algorithm results in fast convergence, minimum computational and settling time, better accuracy of tracking the signals etc. The effect of the developed algorithm is observed in a power system signal through simulations. Effectiveness of the developed algorithm is also examined using Arduino micro-controller. A comparative analysis is made between the Newton Type Algorithm (NTA) and Improved Newton type algorithm to prove the effectiveness of the developed one.

Abstract

This research article deals with modified and ideal plan parameters of 1HP three phase squirrel cage induction motor working under rated voltages. The simulated results are calculated with the assistance of JMAG Express (an electrical machine design software) under rated voltage. Based on the simulated results of stator and rotor design of 1 HP three phase squirrel cage induction motor is casted in the industry. The experimental results of a new 1 HP motor are compared with experimental results of standard motor of the same rating which was designed at rated voltage. The after effects of new planned motor was better when compared with old one. These types of low rating induction motors can be used in the villages for agribusiness and domestic purposes to show signs of improvement effectiveness.

Abstract

Most of the world's energy sources are come from conventional ones namely fossil fuels such as oil (petrol, diesel, etc.), coal, and of course natural gases. However, the alarming decline in the levels of fossil fuels is a clear sign of its rapid and early extinction. Hence demand for a renewable energy sources increases as it is environment friendly and pollution free, and reduces the greenhouse effect. Introducing renewable energy is one of the solution for the issue, among others PV and wind energy are clean and abundantly available in nature. The advantage of utilizing renewable resources over conventional methods lies in significant reduction in the level of pollution. The cost of conventional energy is mounting and solar energy has evolved to be a latent alternative. Solar energy is abundant, pollution free, distributed throughout the earth and is recyclable. The Photovoltaic (PV) systems output power fluctuates according to the irradiation and temperature (weather conditions). Irregular PV output power results in frequency variations in the power systems, especially when the penetration is high. The power generated through PVs or other dispersed power source has to be connected to conventional power grid. PV power is embedded to the grid at substation level, this helps to extend more reliable, and better grid quality power. The hybrid power system consists of DC-DC converters which offer high dynamic performance and frequency modulation transients, without quantization effects and low-complexity, the key findings of the present task. The main aim of this paper is to design, development of microgrid with Synchronous Reference Frame Control for PV module in MATLAB Simulink environment, and customized for accurate analysis by using PSO-BFOA based Incremental Conductance method to reduce sustained oscillations and fast searching of MPPT, generated FPGA coding for MPPT, and multilevel inverter.

Abstract

In this paper, a new control strategy to capture most appropriate power from the wind system is presented with the help of Closed Loop Current Control (CLCC) and rotor speed regulation of Doubly Fed Induction Generator (DFIG). Firstly, wind turbine characteristics and reliable power curve are presented. Complex power decoupling control is achieved from the principle of rotor oriented field control. To maximize the power generation of a wind-driven DFIG, New control method is proposed considering the effect of saturation in both main and leakage flux paths. This method can be achieved by applying a vector control techniques with a neuro-fuzzy gain scheduler. The overall DFIG system performance using the proposed neuro-fuzzy gain tuner is compared with the conventional PI controllers.

Abstract

This paper reviews various types of electric vehicles such as Plugged-in Hybrid Electric Vehicles [PHEVs], Hybrid Electric Vehicles [HEVs] and Electric Vehicles [EVs]. These vehicles are operated by the source of electrical energy having very high torque electric motors. The electrical vehicles consist of various components to generate power. The source of power for these types of electric vehicles to generate power for the operation are batteries, ultra-capacitor, and the fuel cells. Various types of batteries are presently being used as the power source in the electric vehicles. The fuel cells and the ultra-capacitor have various advantages as they are cost effective and better when compared with conventional fuel. This review is very much important for the future study and various ongoing research on this topic.
