The wind power as a clean energy has been researched and developed by many countries. The onshore wind turbine has difficulty to secure additional location by the depletion of good location and the increase in civil complaint. Therefore, it is essential to advance to the sea. However, the mechanical and electrical allowance that components of wind turbine must withstand was increase in a corres...

Development of large scale offshore wind and marine current turbine farms implies to minimize and predict maintenance operations. In director indirect-drive, fixedor variable-speed turbine generators, advanced signal processing tools are required to detect and diagnose the generator faults from vibration, acoustic, or generator current signals. The induction generator is traditionally used for ...

This paper proposes the development of an appropriate control system for the real-time management of large offshore Doubly-Fed Induction Generator (DFIG) based wind farms, connected to the transmission network by Voltage Source Converter High Voltage Direct Current (VSC-HVDC) link. In this plant layout, variable frequency operation lets wind turbines to work on a wider range of wind speed value...

A simulation-based real options analysis (ROA) approach is used to determine the optimum predictive maintenance opportunity for multiple wind turbines with remaining useful life (RUL) predictions in offshore wind farms managed under outcome-based contracts, i.e., power purchase agreements (PPAs). When an RUL is predicted for a subsystem in a single turbine using PHM, a predictive maintenance op...

The need for different numerical models with varying degrees of simplification for the conceptual design of a floating offshore wind turbine is the focus of this paper. While parts on the component level can be designed apart from the others the overall dynamics on the system level have to be assessed from the beginning. Starting with very simple models and identifying the significant contribut...

Floating platform concepts offer the prospect of harvesting offshore wind energy at deep water locations for countries with a limited number of suitable shallow water locations for bottom-mounted offshore wind turbines. The floating spar-buoy concept has shown promising experimental and theoretical results. Although various codes for a detailed simulation exist the purpose of this work is to el...

Floating Offshore Wind has the potential to provide an effective solution for increasing energy demand of coastal communities around world if specific risks associated with this novel technology are understood and evaluated. In paper enhanced risk matrix methodology was developed assessment a generic FOWT through introduction third parameter namely ‘technology category’. The final score is calc...

The national capacity around the world has focused to the development of renewable energy in order to respond to energy, environment, security and economic. Among them, the unit price of wind turbine was reduced by technical maturity. So, the comparative advantage against other renewable energies can be achieved because of proximity to the unit price of the existing fossil fuel. In other words,...
