  • electrical aspects of wind turbines - electricity and modern wind turbines;
  • wind turbines, and related issues - generators, generator starting and synchronization, power converters and ancillary electrical equipments;
  • complex impedance, and phasor voltage - in determining phasor current and vice versa;
  • reactive power, measured in units of ‘volt-amperes reactive’ (VAR) - produced on system;
  • concept, in understanding electrical conversion devices - as transformers and rotating machinery, that of ‘reluctance’;
  • synchronous machines, used as generators - in large central station power plants;
  • wind turbines with synchronous generators - normally started by wind, unlike turbines with induction generators;
  • induction machines, or asynchronous machines - used for motors in industrial and commercial applications;
  • theory of operation of a squirrel cage induction machine;
  • controlled bridge rectifier - using three-phase supply
