Waveform Driven Event Mitigation of PV System using Active Filtering for Controlled Converter Load

Abstract: In Proposed architecture proportional integral based power quality enhancement PV generation system is designed for current harmonics mitigation, improve power factor and compensate reactive power for three-phase three-wire system. Structure consists of SVPWM based three phase inverter supplied with standalone photovoltaic system, self-supported DC bus, shunt active power filter controlled with proportional integral controller and non-linear load. Boost converter incorporated with perturb and observe maximum power point tracking technique is used to acquire maximum output from photovoltaic array. Power quality issue waveform driven event harmonic is caused due to non-linear load (NLL). Implemented system can effectively mitigate the current harmonics and improve power quality. Total harmonic distortion of the source current is obtained below IEEE-519 standards. We can see effectiveness of developed system from simulation results obtained from simulation modelling in 2015(b).

Modelling Rajasthan Assembly Election: Sentimental Analysis of Rajasthan Political Twitter Data

Abstract: With emergence of social media, data is growing daily exponentially. Various stakeholders processing this data and creating application to cater the need of different sections of the society. From last two years world has witness how fate of two countries changed by social media by changing voters’ choices. Social analyst are now using social media and work for different political parties to influence local voters by sharing their ideologies, work and manifestos. This paper works on data of 2018 election and confined to Rajasthan state where data of tweeter was collected belonging to party chief person, political pages and analyses them using python tweepy api. Paper also use KNN algorithm to trace out the type of text or hashtags trending during elections and try to decode the ideology behind these texts and find out how tweets sentiments work and influence people.

Comparative analysis of isolated and non-isolated quasi impedance source converters

Abstract: The impedance source converters are becoming popular in ac-dc, dc-dc, ac-ac and dc-ac power conversion. Different designing methods among these impedance network are used for the construction of impedance source network, in which quasi impedance source network is very popular. The quasi-impedance source network is designed with the different component arrangement of the conventional impedance source network. In this paper, the comparative analysis of isolated and non-isolated quasi-impedance source AC-AC converter is presented. Both topologies contain all the merits of the conventional impedance source AC-AC Converter as well as additional benefits. MATLAB simulation result of both the techniques are presented in this paper.

A study of electric and magnetic polarizations on a piezoelectromagnetic media weakened by two unequal collinear semi-permeable cracks

Abstract: The problem of two unequal semi-permeable cracks is analytically studied for two-dimensional (2D) arbitrarily polarized piezoelectromagnetic media. The electric and magnetic poling directions make ...

Social acceptance of a biomass plant in India

Abstract: Social acceptance of an electric power generating biomass plant is outlined in this paper. The need for social acceptance for diffusion of renewable energy technologies in the society has been emphasized in this paper. The study concerned is about survey of 167 persons, who are residing near the 8 MW power plant at Rangpur on the outskirts of Kota city in the state of Rajasthan in India. The questionnaire contains 14 questions to every person and answers have been obtained after interviewing them personally. This sample study shows that the respondents are though financially benefited, some are against for the establishment of biomass power plant near their agriculture fields.
