Study on Transmission Line and Associated Varying Parameters, Devices and Control Algorithms

The transmission line is the most important part of the electricity network. The need for electricity and its affiliations have increased exponentially in modern times and the main task of a transmission line is to transmit electricity from the area of ??origin to the distribution network. The explosion between limited production and huge demands placed more emphasis on reducing power losses. Losses like transmission loss and also conjecture factors as like as physical losses to various technical losses, another reason is that reactive power and voltage difference in the long distance transmission line are of great importance. In essence, fault analysis is a very important topic in network technology in order to eliminate errors in a short time and restore the electrical network as quickly as possible with minimal interruptions. However, detecting errors that interrupt the transmission line is in itself a difficult task to look for errors and improve system reliability. The transmission line is vulnerable to all parameters that connect the entire electrical network. A review of the transmission and associated equipment was described in this study. And it explains the classification and fault detection scheme. This document provides an overview of transmission line failure detection

Review On Electric Traction Systems Driving Induction Motor and Associated Power Quality Issues

The traction systems for electric vehicles have advanced considerably over recent years, with the application of different topologies of power converters for the control of various types of electric induction motors and permanent magnet. Furthermore, the evolution of power semiconductor elements of Si to SiC wideband have opened up lines of research and development in this area. The trend of manufacturer’s traction systems is to reach compact systems where the power dissipation is high and the reduction of losses is minimal, for it the implementation of topologies of converters with SiC devices seems to be a good alternative of use to improve the performance of these systems. This paper studies the basic topologies of back to back converter in traction systems als well as the powr quality issues arriving in these systems

Study on Micro Grid and Compensation Parameters with Solar/Hydro DGs

Hydropower energy is one of the most suitable and efficient sources of renewable energy which depends on the energy of flowing water. The power capacity and facility are two criteria required for the classification of the hydropower plants. The first one consists of five technologies: dammed reservoir, run of river, pumped storage, in-stream technology, and new technology gravitational vortex. The other one is classified according to the power scale is Large, Small, Mini, Micro, and Pico Hydropower. Nowadays most of the rural areas in developed and developing countries use the hydropower plant for producing electricity, it is cheap and effective. This paper gives a review of hybrid system i.e. micro hydropower technologies and solar energy, it is focusing on the categories and performance of hydropower systems and the most suitable solar energy which can be used.&nbsp
