Diverse models of voltage flicker are established by researchers. Each model has its own disadvantage. In this paper analysis of various models is done. The models consist of various wind turbine parameters like wind turbine tower height, surface roughness of the region, building height if the turbine is mounted on a building or hill height and slope of the hill on which the turbine is mounted. Sixth order model is most appropriate for wind turbine output voltage flicker. © 2017 IEEE.

Sixth order model of wind turbine voltage flicker considering vertical wind shear

In today’s world, electric hybrid vehicle (EHV) is a prevailing vehicle technology in that the major part is electric battery and lead-acid battery is the widely usable battery in the EHV because of its cost and efficiency. The real disadvantage in lead-acid battery is that it easily sulfates because of improper charging or discharging. Hence, desulfation circuit or charge controller is placed along with the rechargeable lead-acid battery for proper charging and subsequently sulfating gets reduced. Numerous research techniques are proposed for this desulfation or charge controlling are inspected in this paper. The desulfation or charge controlling of lead-acid batteries done based upon various techniques and our audit made according to various methods such as pulse width modulation, pressure feedback, resonant frequency, chemical reaction and artificial intelligent. Eventually, the direction for the future research is talked about in view of the survey investigation.

A broad review on Desulfation of Lead-Acid Battery for Electric Hybrid Vehicle

This is paper presents significance of vertical wind shear. Voltage flicker that may be initiated in the output of the horizontal axis upwind wind turbine located at any given site for a given tower height and blade length. Vertical wind shear is one of the important parameters which instigate voltage flicker in wind turbine output voltage. In this paper diverse origins of flicker, places where wind shear occurs, computation of wind shear, general impacts of wind shear, impact of wind shear on wind turbine output is discussed. © 2017 IEEE.

In this paper wind turbine blade is formed as a capacitor. The ice accumulated on the wind turbine blade is removed by dielectric heating. High frequency supply is used for heating. The metallic plates are embedded in the wind turbine blades when the blade is being manufactured. The metallic plates are separated by the insulation medium. The plates are completely coverd by the insulating material. This construction also enhances the strength of the wind turbine blade due to reinforcement by the metallic plate. The supply is given to the blade capacitor when the ice is accumulated. The ice is sensed by ice sensor. The supply to the capacitor may be given by the battery bank. The wind turbine is stopped when the ice is being removed by dielectric heating. The area below the wind turbine is vacated. The human beings and animals are not allowed to go near the turbine as the ice may fall below and the person or animal may be injured due to ice. © 2017 IEEE.

Deicing of wind turbine blade by high frequency dielectric heating fabricating blade as a capacitor

In a conventional wind rose only wind frequency, magnitude, and direction of wind for a particular site is given. But in this paper vertical wind shear is also represented in a wind rose for eight directions. In that diagram minimum vertical wind shear and maximum vertical wind shear for a particular site is represented. For calculation power exponent law is also used. Representation of vertical wind shear in a wind rose is the research component in this paper. The wind rose for vertical wind shear may be useful to predict the flicker initiated in the wind turbine. in this research readings are taken at different sites like Parwati hill, Jambhulwadi lake and Taljai hill in the Pune city. The wind rose of vertical wind shear for one of the sites is given. © 2017 IEEE.

Hybrid Electric Vehicle (HEV) technology is most upcoming in automobile industries, to reduce the pollution and fuel consumption. Lead acid batteries are mostly used in the automobile industries, because of its high efficiency and low cost. However a major problem can arise in the lead-acid battery is sulfation, which occurs because of improper charging and discharging. Sulfation is a chemical reaction that happened inside the lead-acid batteries but it can reconstruct without chemical experiment. The main intension of this proposed work is to develop a Battry Management system for (HEV), to increase life of battery. In the proposed work , lead-acid battery is coupled with the ultracapacitor along with an intelligent controller scheme. For controlling charging and discharging of battery a pulse width modulation (PWM) technique used along with a fuzzy controller. The parameter considered in the control scheme are temperature, voltage, current etc., based on this the pulse signal will be generated. The overall proposed system can enhance the life time of the lead-acid battery. From this work we obtained a well suitable solution for battery management system for the HEV, which can enhance the battery life.The proposed system is implemented and verified using Matlab/Simulink platform. © 2016 IEEE.

Lead-acid battery for HEV using fuzzy controller and ultracapacitor

Pole placement approach of controller design is capable of providing system stability, setpoint tracking and disturbance rejection. The proposed work focuses on design of a digital controller using pole placement method for magnetic suspension ball system which is an open loop unstable system. The digital controller design is a 2-DOF controller using the transfer function approach for given constraints in terms of peak overshoot and rise time. The objective is to determine a controller which satisfies the specialized constraints. This paper introduces design process for a digital controller using pole placement method for a magnetic suspension system.
