Energy microgeneration

Microgeneration is the generation of power on a small scale – for individual homes, communities or in emergency situations. Microgeneration is also important if you are on the move and isolated from the grid e.g. while boating or in a recreational vehicle.  the move – for boats or recreational vehicles. The Oxford Microgeneration System converts mechanical energy from wind, water or any other means into electrical power.

The current Oxford system generates heat directly into a boiler and can supply the grid from wind power. This system has been running without maintenance for 9 years. The system is also designed to drive cooling systems and feed into battery storage. At the heart of the system are reliable electronics that optimise power and can be networked using SIM-based communication.

Microgeneration

Microgeneration is the small-scale generation of heat and electric power by small businesses and communities to meet their own needs as an alternative to traditional centralised grid-connected power. Examples of microgeneration vary from small scale wind turbines to ground source heat pumps.

The Oxford microgeneration system

The Oxford microgeneration system makes use of off-the-shelf induction motors with variable voltage and frequency output as the core of a highly efficient energy conversion system.

  • Cost Savings: Significant cost reduction across all sizes, due to mass produced off the shelf components replacing and eliminating custom made small volume components
  • Proven: 10 kW prototype has run successfully in Ireland for over 7 years.
  • Scalable: Induction motors commercially available from kW to over 10 MW size.
  • Reliable: Reduction of parts (no mechanical gearbox) and the use of mature, mass-produced components such as the induction motor leads to much-improved reliability. Induction motors are known to be robust in harsh environments.
  • Low maintenance: No mechanical gearing required.
  • Safe: Reduced head weight improves the safety of the tower. Special design features for increased safety in high wind and lightning.
  • Big data: SIM-based networking and monitoring. Informed reliability.
  • Low noise: Mechanical gearboxes are notoriously noisy – replaced with a noiseless electrical gearbox.
  • Weight reduction: By removing mechanical gearing.
