Abstract:

Having as common focus the innovative developments in renewable energy, the project consortium brings together university, academic and scientific research organizations whose objectives converge towards performance improvement by supporting existing institutional research capabilities. The project aims to optimize renewable energy production facilities and to develop functional models which will ensure electric power supply with integrated natural sources, especially in disadvantaged areas, by applying new and emerging technologies. Starting from the complex electricity generation systems, which are patented/in process of being patented at national level, and with the contribution of the coordinator and the partner institutions that will develop the component projects, the integrated generation-supply assemblies will be validated under relevant operating conditions. Within the project the complementary partnership for innovation is promoted, the members having a well-defined role within the consortium, each contributing to the significant optimization of the complex systems for renewable energy production in both coastal areas and for flowing waters, improvement of hydrogenerators, and realization of pilot models for demonstration and provision of thermal and electrical energy. This project provides the necessary support to strengthen the scientific and technical competencies through the correlation and coordination of activities and resources within public research organizations and the capitalization of these competences through research results provided to the socio-economic field. The project implementation leads to the improvement of research infrastructure at the consortium level and to the reinforcement of institutions capacity through the formation and involvement of the newly employed human resource, in order to acquire new knowledge in the field of innovative technologies for energy production from renewable resources in integrated complex installations.

Abstract:

The low energy consumption and the power quality requirements impose a better design of every technical component for energy production, distribution and consumption. At the same time, the consumer profile shifting to highly non-linear and distorting loads, and the spreading of renewable energy sources have increased the interest in designing low-loss magnetic cores for electrical machines and transformers, and for miniaturized magnetic components of power electronics parts. The replacement with composite magnetic materials is a commonly used solution, but the associated power losses are not sufficiently understood for higher frequencies or non-sinusoidal regime.

The concept of losses predetermination, which is formulated by the consortium team, is based on the calculation in the time domain, contrasting to the classical method of the approximate formulas in frequency. This makes possible to extend the frequency range of applications, but a systematic experimental validation is required.

The project proposes the conception, design, manufacture and testing of a device for measuring the magnetic nanocomposite cores, aiming the experimental validation of the technology for the magnetic losses predetermination in such cores, for a wide range of frequencies. The experimental demonstrator will also allow the selection of nanocomposite materials with low losses. The project results will contribute to the energy efficiency improvement of equipment containing magnetic cores, in the design phase, through a more precise predetermination of magnetic (iron) losses at higher frequencies or under harmonics imposed by real working conditions. One will identify the energy parameters’ values of estimation formulas for the magnetic losses (classical, by hysteresis and excess losses), as well as the forecasting functions available at higher frequencies.
