EVALUATION OF OCEAN-ENERGY CONVERSION BASED ON LINEAR GENERATOR CONCEPTS

As the world continues to demand greater productivity and lifestyle enrichment through technological advancements, the demand for electrical power is predicted to escalate dramatically.

Thus far, this increased demand has been primarily supplied from fossil fueled plants. Unfortunately, the burning of fossil fuels produce harmful carbon dioxide pollution as a by-product. It has been hypothesized that unless a clean, renewable, and efficient alternate source of energy is found soon, the world may either exhaust its supplies of energy-producing materials or drastically degrade its environment. However, motions that occur naturally, such as ocean waves, can play a significant role in generating environmentally safe and economically viable energy for human utilization.

The focus of this work predicts the electrical power generation capabilities from a seabed mounted linear generator tethered to a floating buoy heaving under the influence of passing ocean surface waves. Mathematical models are introduced which simulate the oceans’ surface conditions under both the regular (basic) and irregular (natural) wave regimes, the heave (vertical displacement) response for a floating buoy, and the resulting electrical output parameters of the linear generator. Within these models, various physical and electrical parameters are altered in an attempt to generate a greater output power for a given sea state condition, making the Wave Energy Converter (WEC) more efficient. It is shown theoretically that the buoy can be designed to have a greater heave response than that of the height of a passing wave resulting in an increase in generated power from the linear generator.

This research text provides a detailed look at the equivalence between the thermal system of equations and the variables of circuit theory. This relationship is used together with SPICE (Simulation Program with Integrated Circuits Emphasis), to accurately model heat flow with traditional methods in electrical engineering.

The book details the computational complexity of heat flow and why an electrical analogue to the thermal system improves the efficiency and computational speed of the solutions.
