Abstract: The methodology for design of variable length blade is proposed in this project. The power produced at any given time is thus dependent on wind velocity and the rotor swept area of the turbine. Wind is variable in availability and consistency, thus to extract more power from the same variable velocity, it is required to vary the diameter of the rotor. In order to capture the maximum power the rotor diameter must be increased during low wind speed and decreased during high wind speeds. A variable length blade can adapt length variation to accommodate low wind velocities as well as high wind velocities during extreme conditions by extension and retraction mechanism, thereby increasing the operational time and power production of the turbine.

Keywords: Wind power, variable length, high wind speed, low wind speed, constant power

Abstract: Paralysis is one amongst the major neural disorder that causes loss of motion of one or more muscles of the body, wherein depending on the cause, it may affect a specific muscle group or region of the body, or a larger area may be involved. In pursuit of rehabilitation, the eye can be regarded as one of the organs that can help a paralyzed person to communicate suitably. Eye movement can be used by the paralysis patients and armless persons to perform simple tasks. This paper describes the acquisition and analysis of eye movements for the activation of home appliances for paralysis patients................

Abstract: Providing complete monitoring on the presence of various toxic gases in large scale petrochemical plants is critical, since the leakage of these can cause serious effects on the production activities and safety of first line workers. Safe production environment can enhance the productivity and keep high profits of enterprises. In this project, we present a newly developed mobile car with WIFI based wireless communication to smartly monitor and track the presence of various toxic gases. With the current system, which consist of stationary gas leakage detecting modules fitted at different parts of the industry, can only monitor leakage of gas at a particular region only. It also creates an issue that to extend the range of monitoring of gas leakage number of such modules needs to be more and hence the cost is more............

Abstract: This paper describes the operation of a separately excited dc motor for EV application. Battery fed electric vehicles (BFEVs) are required to function in two different modes namely: acceleration mode and braking (regenerative) mode. During acceleration and normal modes the power flow is from battery to motor whereas during braking or regenerative mode the kinetic energy of the motor is converted into electrical energy and fed back to battery. Four quadrant and two quadrant operation of electric vehicles are implemented in this paper.

Abstract: Now-a-days with the inadequacy in energy and continually enlarging fuel cost, investigation on the renewable energy becomes more and more important. A boost converter is a switch mode dc to dc converter in which the output voltage is greater than the input voltage. Different traditional converters like boost converters tolerate high transient current and conduction losses as the switching frequency is varied. Ripple occurs in DCDC converters due to the switching transients. In order to overcome the above-mentioned drawbacks, the interleaved boost converter is used. The comparison between conventional and interleaved boost converter was simulated and analyzed using MATLAB/SIMULINK.

Abstract: The relevance of multilevel inverters has been increased since last few decades. These new types of inverters are suitable for high voltage and high power application. These inverters are able to synthesize waveforms with better harmonic spectrum and with less Total Harmonic Distortion (THD). Numerous topologies have been introduced and widely studied for utility of non-conventional sources and also for drive applications. This report presents information about several multilevel inverter topologies, such as the Neutral-Point Clamped Inverter and the Cascaded Multilevel Inverter. from among these some multilevel inverters will also be compared with a new topology with reduced number of switches. The THD values will also be compared. The modulation method used will be Sine PWM. The study will be mainly dealing with seven level inverter topologies.

Abstract: The paper discuss the idea of operating an inverter to mimic a synchronous generator(SG).Using such inverters,the theory or algorithms used to control synchronous generators can be used in power systems where a significant proportion of the generating capacity is inverter based.Similar to other grid connected inverters,it needs a dedicated synchronization unit,eg: a phase locked loop(PLL),to provide the phase,frequency and amplitude as references.In this paper ,a radical step is taken to improve the inverter as a self-synchronized inverter by removing the dedicated synchronization unit.Such inverters can automatically synchronize itself with the grid before connection and track the grid frequency after connection.This will considerably improves the performance ,reduce the complexity and computational burden of the controller.

Abstract: The electrical energy plays an important role in human life. The generation and distribution of electrical energy is a big task and it involves so many procedures. The countries like India is facing scarcityof electrical energy due to the non availability of sources like water and others. So it is required to think the methods to generate electricity from other ways to meet the dialy needs. The wastage of energy should be avoided and suitable methods should be implemented for the conversion of such energy into useful form. Renewable energy is the energy which is obtained from renewable sources such as sunlight, wind, pressure, tides etc/-. Elecricity is produced from sunlight using solar panels..............

Abstract: Nowadays gas leakage and gas detection is a major problem in our daily lives. Also gas wastage is a major issue that needs to be countered. LPG gas is highly flammable and can inflict damage to life and property. To avoid such situations, a considerable amount of effort has been devoted to the development of reliable techniques for detecting gas leakage. As knowing about the existence of a leak is not always enough to launch a corrective action, some of the leak detection techniques were designed to allow the possibility of locating the leak. Our aim is to reduce the risks in Kitchen using Internet of Things

Abstract: The DC-DC converters are widely used in photovoltaic generating systems as an interface between PV module and the load. These converters must be chosen to be able to match the maximum power point (MPP) of PV module when climatic conditions change with different resistive load values. So DC-DC converters must be used with MPPT controller in order to reduce losses in the global PV system.The nonlinear power characteristic of PV greatly depends on the environmental conditions. Hence in order to draw maximum available power, various algorithms are used with PV voltage/current or both as an input for the maximum power point tracking (MPPT) controller...........
