Development of an energy optimiser for asynchronous motors

Objective



The objectives of this proposal are:
- the development of an Energy Optimiser for asynchronous motors;
- the development of an adaptive controller;
- the development and incorporation into the controller of a parameterestimation algorithm;
- an assessment of the EMC aspects of the device;
- an assessment of the energy savings potential of the device;
- the measurement of the energy savings during laboratory motor tests;
- the measurement of the energy savings during laboratory heat pump test(for domestic heating systems);
- the measurement of the energy savings during field test in variousapplications, and its statistical assessment;
- a comparison of the Energy Optimiser savings potential against the muchmore expensive variable speed option.
In the European and the Central European countries and the New Independent States, an estimated number of 40 million asynchronous motors are used which are loaded with variable torque. With an appropriate reduction of the electric loading of the machine, while in partial mechanical load, energy savings of 10 % to 50 % are feasible. This indicates a huge potential for a device that would accomplish this task. For instance: a rough estimate of the energy savings using the proposed devices when only heat pumps would be used in residential heating systems amounts to 3.5*10l7 J/year. This is about 10 % of the total energy used for heating (40*107 J/year) in that case.
In the project, tasks are allocated to the various partners in order to accomplish the objectives stated above. For each objective a (sub-) task has been defined such that successful completion of the task should lead to accomplishment of the corresponding objective.
