For offshore wind energy, there is a trend toward larger wind turbines. The increased mass of a power-takeoff system increases the installation cost of the turbine. Direct-drive superconducting generators have the potential to reduce the installation cost of wind turbines. For a successful entry to the off-shore-wind-energy market, a high-temperature superconducting generator should be as reliable as conventional generators. It is proposed that a stationary superconducting direct-current-field winding may increase the reliability of the generator. An axial-flux homopolar generator topology is proposed to be used in low-speed high-torque applications. The topology is modified by using two superconducting field windings to obtain a bipolar flux-density distribution for higher power density. Different core types and dimensions were examined to find the most suitable design, and a conceptual design of a 6-MW 12-r/min generator is presented.

A modular and cost-effective superconducting generator design for offshore wind turbines
Keysan, Ozan (IOP Publishing, 2015-03-01)
Superconducting generators have the potential to reduce the tower head mass for large (similar to 10 MW) offshore wind turbines. However, a high temperature superconductor generator should be as reliable as conventional generators for successful entry into the market. Most of the proposed designs use the superconducting synchronous generator concept, which has a higher cost than conventional generators and suffers from reliability issues. In this paper, a novel claw pole type of superconducting machine is p...
Development of a superconducting claw-pole linear test-rig
Radyjowski, Patryk; Keysan, Ozan; Burchell, Joseph; Mueller, Markus (IOP Publishing, 2016-04-01)
Superconducting generators can help to reduce the cost of energy for large offshore wind turbines, where the size and mass of the generator have a direct effect on the installation cost. However, existing superconducting generators are not as reliable as the alternative technologies. In this paper, a linear test prototype for a novel superconducting claw-pole topology, which has a stationary superconducting coil that eliminates the cryocooler coupler will be presented. The issues related to mechanical, elec...
Multiobjective Optimization of the DC-DC Stage of a Module-Integrated Inverter Based on an Efficiency Usage Model
Mirjafari, Mehran; Balog, Robert S.; Turan, Raşit (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-01)
As photovoltaic (PV) energy continues to gain market penetration due to the lower cost of PV modules, attention is shifting to the balance of system. In this paper, a new efficiency evaluation technique based on a usage model that is synthesized from high-temporal operational data of a PV module is investigated, along with a multiobjective design optimization of the dc-dc stage of a module-integrated inverter. The analysis shows that the technique provides more accurate results than the California Energy Co...
OPTIMAL CONTROLLER DESIGN FOR SPEED GOVERNORS OF HYDROELECTRIC POWER PLANT
Altinoz, Okkes Tolga; KOŞALAY, İLHAN; Gezer, Derya (VSB - Technical University of Ostrava, 2020-06-01)
Speed governors have critical importance on hydroelectric power plants, which are adjusted to the rotating speed of hydroelectric generation based on load demand of the grid. The rotating speed is the main factor to balance power generation and load demand. The well-designed controller is needed to control speed governors with high accuracy. A well-defined model is needed to obtain desired control structure. Therefore, in this study, initially, the mathematical model of a hydroelectric power plant is obtain...
Improvement in dye sensitized solar cells from past to present
Mohiuddin, Obaidullah; Obaidullah, Madina; Sabah, Cumali (Springer Science and Business Media LLC, 2018-10-01)
Several emerging renewable technologies are available to satisfy the current energy demand and to minimize the effect of environmental degradation caused by high consumption of fossil fuels. These technologies are not mature enough to solve this problem but require more time for improving the efficiency, and cost reduction to become the economical alternative of fossil fuels. In this paper Dye-sensitized solar cell (DSSC) has been discussed in detail owing to advancement in the technology. Since each compon...
