Tittle:
Innovative energy-saving and power-smoothing device for elevators, renewable energy sources and electric vehicles
Summary:
A Greek university laboratory specialized in developing prototypes for energy-saving electric motion applications, has created a device for storing and re-using electrical energy generated in the braking operation of a motor. It can be used for various industrial and domestic applications. The client is looking for industrial partners in the UK, Germany, France, Austria, and Spain interested in a technical co-operation agreement for commercial development and exploitation of the prototype.
Description:
This Greek university laboratory is specialized in the development of control techniques and prototypes for energy saving in several industrial and domestic electric motion applications (such as elevators, renewable energy sources, electric vehicles, embedded systems and servo motor drives). It has acquired significant experience and a high level of know-how in its specific field, and has participated in a number of national and EU-funded research projects.

The university lab has developed an energy-saving device that can be applied to a variety of electric motion systems. The electrical energy that is generated in the braking operation of a motor drive is temporarily stored in supercapacitors (or a combined system of supercapacitors and batteries). It can then be recovered and used when the electrical machine turns to motoring operation. Thus, improvement in the efficiency of the whole motion system is achieved. The above device can also be used in renewable energy systems for power smoothing (to improve the quality of the power and to regulate for constant flow), as well as for active filtering of the electrical current.

The main activity of the Greek laboratory is to conduct research in all aspects of electrical machines. In recent years, its staff members have worked on projects (supported by industry and the European Union) related to: the design, construction and testing of electrical machines; the design and implementation of controls for machines and power electronics; the fault diagnosis and failure prognosis in simple and complex drive systems; and the development of power electronics subsystems.

Its primary research activities are in the following areas:-
- design and analysis of electric machines,
- power electronic converters,
- design and modelling of electric machine drives,
- loss minimization control for electric machine drives (motors and generators),
- control and design optimization of electric motors and generators,
- energy conversion systems for renewable sources (wind and photovoltaic systems) and
- energy saving in domestic applications.

For over 3 decades, the laboratory personnel have worked on issues related to efficiency optimization in electric motor and generator drives. They have developed control techniques for almost all the most widespread types of electrical machines, in other words: direct current (DC); induction; permanent magnet (PM) synchronous; switched reluctance; synchronous reluctance motor drives as well as single-phase induction motor drives. They have developed efficiency optimization control techniques for horizontal axis wind turbines (with induction, PM synchronous and doubly-fed induction generators) and an innovative sensorless and low-cost yaw control system (responsible for the accurate alignment of the wind turbine rotor to the wind direction).

The Greek client is looking for collaboration with industrial partners from the UK, Germany, France, Austria, and Spain that are interested in technical co-operation agreement for commercial development and exploitation of the specific electric motor energy-saving device prototype.
Advantages and Innovations:
The novelty with this device is the control technique employed that provides optimal exploitation of the energy storage and thus, an improved cost-effectiveness ratio and further increase in energy saving. Additionally, effective protection of the lifetime expectancy of the supercapacitors and batteries is attained.

Another advantage of this energy-saving system is that it can be easily installed without requiring difficult parameterization of the controller and without requiring any modification in the main drive of the application. Thereby, the new device can be used in existing installations that are already in operation.

One final and very important advantage of the new device is its low manufacturing cost for the same energy storage capacity, compared to other systems that are already available on the market. This is achieved by the innovative design of the device and due to the optimal exploitation of the energy storage capability.

This device is also user-friendly and, through a touch screen display, the user can monitor the operation of the whole system and can be informed in real-time on the energy saving that is obtained.
