The International Specialized Exhibition „Moldenergy”

The International Specialized Exhibition „Moldenergy”, 17 -20 .03.2010.

Institute of Power Engineering of the ASM and ELIRI S.A.

From March, 17 till March, 20th 2010 on MOLDEXPO took place 14th International Specialized exhibition MOLDENERY.

The Institute of Power Engineering of the ASM was the full member of the Exhibition.

There were presented results of investigations in the field of energy transmission, the use of the renewable energy (solar, wind, the production of hydrogen by means of electrolysis, heat pumps), resistive high voltage dividers 6-35 kV produced from the microwire. There were presented the mockup of solar water heater and models of high voltage dividers DRT 6,3 kV, DRT 24 kV and DRT 35 kV. Visitors of exhibition manifested the particular interest to simple in realization models for obtaining and the use of renewable energy elaborated in IE ASM. The basic feature of these innovative solutions is lower cost of manufacturing of converters of energy in comparison with their foreign analogues. Visitors took an interest in a solar water heater with temperature stabilization of heated water up to 55 ^OC. It is used the effect of thermostabilization on the basis of phase change material is used. Thermal energy accumulation in the water stored in polyethylene container, is the successful technical decision - simple, cheap and reliable. Obtaining of hydrogen with the expense of the electric power less, than energy of the received hydrogen, attracted interest of manufacturers of the plasma cutting instrument, who use now old, power-consuming ways of obtainment of hydrogen. Experts in the field of transport showed their interest in hydrogen use in internal combustion engines. In the course of dialogue with visitors it was found out, that they have the problems, demanding new scientific and technical decisions. The general request of visitors: payback period new of energy sources must be less than two years. It took place the round table on a theme „Electric resistive transducers and the equipment for measurement of a high voltage 6,3-35 kV of an alternating current”. 38 persons participated in work of the round table. There were presented next reports:

1. Dividers from the isolated microwire for measurement of a high voltage of an alternating current (6,3-35)kV Berzan V, dr.hab. (IPE ASM), Badinter E, PhD (ELIRI S.A).

2. Metrological assurance of high-voltage dividers of an alternating current of type DRT 6,3-35 kV. Kleymenov В, ELIRI S.A.

3. Voltage dividers signal processing. Sit М, PhD, IE ASM.

4. «Creation and development of testing area of Renewed energy sources „ Chişinău ” » was presented. Berzan V В, dr.hab., V.Anisimov, PhD., V.Burchiu, dr.hab., M.Tyrshu PhD., all from Institute of Power Engineering of the ASM.
