This work presents a proposal to correct the power factor in the 13.8 kV auxiliary service bar of the Sobradinho hydroelectric plant using the three-phase DC-AC converter, which is part of a photovoltaic generation system from Chesf (Companhia Hidroeléctrica do San Francisco). The set of photovoltaic panels forms a floating plant located in the lake of the Sobradinho-BA hydroelectric plant. The proposal of the work consists of using a control technique based on dq components to insert reactive power through the three-phase DC-AC inverter of the photovoltaic plant at the point of connection to the auxiliary service of 13.8 kV of the hydroelectric plant and improve the power factor. If there is no intention to perform power factor correction, it is possible to configure the same proposed control structure so that all energy produced by photovoltaic generation is inserted into the electrical network to which it is connected. For the study, a computational model of the floating photovoltaic plant, energy processing and connection to the electrical grid was developed, using the Simulink/MATLAB® platform.
