Research and Development

According to the current organizational model of the Eletrobras Group, CEPEL restructured its research activities into eight departments. CEPEL once again assigned high priority to strategic and structural projects, to support the Brazilian power companies with the necessary technological expertise in an increasingly competitive energy market. The eight research departments, which may join forces to better develop multi-disciplinary projects, are described below.

Energy Optimisation and Environmental Issues Department

Development of computer programs for the expansion and operation planning of interconnected hydro-thermal systems. The environmental impacts of new projects are fully taken into account in the multi-criteria expansion planning tools.

Special mention should be made to some computer programs developed by DEA, such as MELP (long-term expansion planning), NEWAVE and DECOMP (medium and short-term operation planning) and DESSEM (operation programming). Other computer programs simulate hydro-thermal system operation, assess the reliability of the system, forecast river flows, carry out studies of flood prevention and hydroelectric inventory of river basins. DEA also develops models for load and long-term market forecasting, and investment decision-making in energy generation projects, always incorporating the environmental dimension into planning. Electrical Networks assessment, small signal stability analysis, Department short circuit calculation, transmission expansion planning and optimal power flow.

This department works on the improvement of conventional and on the development of new technologies for a safer and more reliable operation and expansion of the electric system. DLE has developed software for design, cost estimation and optimization of AC and DC transmission lines. Highlights are high surge impedance transmission lines (HSIL or LPNE in Portuguese), with more than 4,000 kilometres HSIL lines currently in operation in . Another highlight refers to the new UHV infrastructure that is currently under construction to perform vital experimental research on transmission line configurations and equipment for UHV transmission systems (±800 kV CC and until 1200 kV AC).

New UHV laboratories, designed for 1.100 kV ac and ±800 kV dc are presently under construction. The External UHV facility has already had its first phase commissioned and is expected to be completed by the end of 2014. It is aimed at long distance UHV transmission lines testing and development, both at ac and dc. It will comprise three 70m high supporting structures, spaced by 110m, that allow great flexibility in the assembling and testing of innovative line arrangements. All the impulse, applied voltage and corona testing sources, both for ac and dc, have already been delivered and most of them commissioned. A corona cage, with 60m x 7,5m x 9m (height), with artificial rain capability, complements the External UHV Laboratory. A UHV Hall, also designed for 1.100 kV ac and ±800 kV dc is now in advanced planning stage. An area of 50,000 square meters, including storage, assembling halls and ancillary facilities, has been allocated to the two laboratories in Cepel Adrianópolis site. Of these, 20,000 will be specifically dedicated to electrical testing.
