2 CEPEL is the largest electric power research centre in the Southern Hemisphere. CEPEL s mission is to provide technological solutions for electric power generation, transmission and distribution. CEPEL was created in 1974 to meet the needs of the rapidly growing Brazilian electric sector, and today occupies a prominent position in the international scene. CEPEL conducts research and development (R&D) projects, producing prototypes and processes and providing technological and laboratory services for the whole Brazilian power sector. It also develops computer programs to support diverse activities, including the operation of the Brazilian electric system, supervision and control of the grid and the expansion of the sector nationwide. CEPEL clients include the companies of the Eletrobras Group, the Ministry of Mines and Energy (MME), public and private generation, transmission and distribution utilities, electrical equipment manufacturers, the Brazilian Electricity Regulatory Agency (ANEEL), the Energy Research Company (EPE) and the National Operator of the Electric System (ONS). CEPEL has a staff of approximately 150 permanent researchers, 70 collaborating researchers and 90 specialist technicians. CEPEL has 34 laboratories equipped with state-of-the-art facilities for carrying out research work and various forms of tests; some of them are unique in Latin America. CEPEL headquarters at Ilha do Fundão, Rio de Janeiro, house 24 of these laboratories; the others are located in the Adrianópolis unit, at 40 kilometers from headquarters. The current infrastructure has installations covering the following fields: high voltage, high current, high power, measurement and calibration, materials, chemical analysis, energy efficiency, superconductivity, fuel cells, monitoring and diagnosis, intensive computing, supervision and control. This laboratory infrastructure has allowed significant improvements to the quality of the electrical equipment produced by the Brazilian industry and promoted technological development in the sector, ensuring greater reliability in generation, transmission and distribution systems. The laboratory services provided by CEPEL include electric studies, metering, technical inspections and equipment performance testing, as well as certification analyses. CEPEL also develops projects on energy efficiency and generation from alternative sources, such as solar and wind energy.

3 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 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.

4 Electrical Networks Research and development of power system network analysis methodologies and computer programs to assist in operation and expansion planning of electric power systems. Development of methodologies and software for planning and operation of the Brazilian interconnected power system. These software ranges from conventional power flow to dynamic security assessment, including electromechanical transients analysis, harmonic analysis, reliability assessment, small signal stability analysis, short circuit calculation, transmission expansion planning and optimal power flow. They are used by Eletrobras enterprises, government, industry organizations and generation, transmission and distribution companies, state owned and private. DRE offers a range of specialized courses and promotes power system engineering education by distributing cost-free user licenses for reduced versions of these software to universities. The department is also frequently involved in special electrical engineering studies that require the expert use of CEPEL s comprehensive suite of computer programs. System Automation Development of tools for data acquisition, real time operation of electric systems and disturbance analysis. The activities of DAS comprise the development of tools for real time operation of Power Systems. The two major products of DAS are: SAGE (Open System for Energy Management) which is a modern, open, modular SCADA (Supervisory Control and Data Acquisition) system, whose superior performance, flexibility and reliability characteristics, place it among the top products in the world market; and SINAPE (Integrated System for Disturbance Analysis) that assists in the post-disturbance analysis of electric systems, including the location of faults. The most important current development is the REGER Project - a joint collaboration of CEPEL with Siemens - that provided the Brazilian National System Operator (ONS) with a distributed supervision and control system with a high level of redundancy and strongly integrated with the other systems of the company. Based on the EMS/SCADA SAGE of CEPEL and the data management system off-line Spectrum PowerCC IMM from Siemens, this solution is implemented in the five ONS control centers.

5 Lines and Stations Development of transmission line projects and technologies to improve equipment used in generation and transmission of electrical energy (software, computer models, testing and metering techniques, monitoring and diagnostic systems). 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 Brazil. 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). Integrated equipment monitoring and diagnostic systems (DianE, SOMA and IMA-DP), which are being progressively implemented throughout the country; development of EHV and UHV testing techniques and measuring systems for on-site and laboratory use, helping to control equipment performance, and also for equipment failure analysis.

6 Special Technologies Research and application of technologies comprising energy efficiency (including sustainability analysis and economic feasibility analysis), renewable energies, metallurgy and materials, and distributed generation. activities include technological support to Brazil s National Electric Energy Conservation Program, and to the Brazilian Ministry of Mines and Energy; design and assessment of the potential of wind farms; design and implementation of small solar photovoltaic power plants; design and implementation of a 1 MW concentrated solar power (CSP) plant; projects in the area of fuel cells and hydrogen generation; and design of hybrid systems (solar/ wind/diesel). Studies and applied research have been carried out on the assessment of the structural integrity and remaining life of the components of thermoelectric power plants; corrosion affecting electric equipment and structures of the electric power sector; and superconductivity. The department has recently initiated studies in the area of nanocomposites and nanofluids. The Ilha do Fundão unit is home to CRESESB the Sérgio de Salvo Brito Reference Center for Solar and Wind Energy, the Efficient Solar Home and CATE Center for the Application of Efficient Technologies.
