MODELLING AND ANALYSIS OF LINEAR ELECTRICAL GENERATOR

Abstract

As we moving further there is increase in demand for sources but unfortunately sources decreasing at alarming rate. Techniques involved in renewable energy are now coming forward as time passes. This not just because scarcity but also due to dangerous after effects of their uses like pollution, greenhouse effect and so many countless adverse impacts of ecology. Thus we need to take support of renewable energy available in tremendous amount. The energy content of oceanic waves is heavy source of potential for society now. Fortunately, technologies related to this also improved a lot. Extraction of wave potential and its techniques are coming and have great interest throughout the world to extract energy from eco-friendly sources like ocean waves. But problem is that now we are having availability of rotational devices to convert energy but in ocean waves flow is back and forth. So we need device that can directly convert energy and provide us the output. Thus here we are working on permanent magnet linear generator(PMLG). Here this technology is called as direct drive technology. Here modelling and analysis of permanent magnet linear generator (PMLG) and also MATLAB simulinking of (PMLG) is being presented. Study of different parameters and how they affect output of (PMLG) in terms of current and voltage.
