DYNAMIC ANALYSIS OF MARINE CURRENT FARM CONNECTED TO GRID

Abstract

The power generation capacity of marine currents is enormous. Marine current power is recognized as a continuous available form of renewable resource witch can be used for sustainable generation of electricity. Due to high predictability and load factor marine current power it is more attractive for power generation and advantageous when compared to the other renewable energies where it is available. It can produce very huge amount of electrical power as compare to wind power due to density of water is thousands times the density of air. In recent years research in the area of marine current energy conversion has been carried out mostly in European countries such as Ireland. The focus has been to develop a simple technology for converting the kinetic energy of oceans into electricity. The principle of converting kinetic energy of marine current into electrical energy is similar to the wind energy conversion technology. The concept is based on a marine current turbine (MCT) coupled with the induction generator that is designed based on the characteristics of the resource. In this thesis stability aspect of MCT has been analysed during evacuation of power through conventional AC transmission line and HVDC line. It has been analysed that the power evacuation from MCT through conventional AC lines may have lesser stability limits in comparison with a parallel HVDC lines.
