Presentation Title: Offshore Wind Energy - Generators and Grid Integration

The world's first full-scale floating wind turbine has been built off the west coast of Norway. The Hywind is part of a plan to move offshore wind farms far away from the coast, minimizing disruption to military radar operations or the shipping industry, away from fisheries, bird life and tourism. The project is at the beginning of a two-year test period, to see if it can stand up to the rigors of the North Sea. The presentation will discuss

  • Technologies for Floating Offshore Wind Turbines and Farms
  • Supergrid, plans in the North Sea
  • Design and Control of the Generators
  • Grid Integration - from Wind Farms to Land or to Oil Platforms
  • Electrification of Oil Platforms from Land
The presentation will address also projects and larger initiatives in alternative and environment friendly energy.

Presentation Title: Nonceramic Line Insulators User Concerns and Challenges to Advance the Technology

The paper provides an overview of the state-of-the-art of nonceramic line insulators, focusing on the major concerns that users have today, in using these insulators, and on the challenges that need to be addressed by both the users and the manufacturers, to advance the technology. Nonceramic line insulators have generally performed well everywhere, but in some instances, the abrupt failure characteristic of these insulators, which has often been catastrophic, has been a major concern in using these insulators, and the reasons for this type of failure are discussed in the paper. Aging of silicone rubber and the loss of hydrophobicity through the gradual loss of low molecular weight siloxane cyclic groups, and the end of life, is addressed. Corona damage to the housing of insulators, which today, is considered to be the major reason for failures, is emphasized. The manufacturing aspects of, swaging of the hardware to the core, and bonding of the rubber to the rod, in the long term performance of nonceramic insulators, are addressed. Also, the operational aspects of damage from flashover and power arc, high temperature operation, and damage due to wildlife, are highlighted. The increased frequency of maintenance surveillance that users are required to do to help prevent failures and the associated life cycle cost are also discussed in the paper.

Presentation Title: Power electronics for renewable energy

Power electronics has developed continuously over the years and are finding increasing applications. There are many power converter circuits some of which have become standard topologies and are available as modules from the manufacturers. This presentation reviews the chronological development of power electronic circuits and identifies circuit topologies for practical applications in renewable energy.

Presentation Title: Self-tuning Adaptive Control

Design of controllers for plants is normally done off-line using a fixed parameter model of the plant linearized for a nominal operating condition of the plant. Plants, in general, are non-linear and their parameters depend on the operating conditions. Such controllers can not provide optimal performance as the plant parameters change. Adaptive control theory provides a possible way to solve the problems associated with fixed parameter controllers.
Self-tuning control is one of the popular adaptive control techniques. Self-tuning control with self-adjusting pole-shift will be the primary topic of this plenary talk. The strengths of this approach will be illustrated using a power system stabilizer as an application example.
