A 68Ge/68Ga generator (IGG100, nominal 1.1 GBq, Eckert & Ziegler, Berlin) was eluted with 5 ml 0.1 N HCl (BioChemica, Sigma-Aldrich-Fluka).
In addition, by decreasing the wind speed, the blade pitch angle is reduced and at this step to fix the power and speed of the generator at nominal value, robust controller was designed.
The turbines will be coupled to two generators with nominal power 5 MW, AC output voltage of 6 kV and 98% efficiency.
Directly connected to the size of the diesel generator, is the nominal power of ORC system, not being a decision variable.
There are assumed 20 identical wind generators in each wind farm, and each wind generator has the nominal capacities equal to 600 kW.
This controller is tried to control the pitch angle for accessing the maximum power electric and tune the speed of generator around its nominal value.
Because of different areas of wind turbine performance, purpose in this article is, fixing the power and speed of the generator at the nominal value in the third performance section.
All generators had a nominal activity of 1,850 MBq and were supplied by iThemba Labs (Faure, South Africa provided by IDB Holland BV, Baarle-Nassau, The Netherlands) [4],[4]].
When RF ablation and MR thermometry are performed simultaneously, the MR images show severe RF interference due to the harmonics of the RF generator (operating at a nominal frequency of the order of 500 kHz) that fall within the reception window of the MR receive chain (centred around the 63.7 MHz carrier).
The pitch angle is controlled in order to limit the generator output power to its nominal value for high wind speeds.
