With energy issues, growing electric energy consumption, and energy availability, more energy sources are being explored. Some of these relatively new power sources are wind, solar and hydraulic power. Eolic electric energy generation and hydraulics produce AC current and photovoltaic panels produce DC current, but these cannot be used directly, they must have the appropriate quality first. With them new opportunities arise, as well as problems, such as power conversion due to the different nature of each generation method. This is where power electronics come into place, allowing the control and conversion of electric power. It focuses primarily on photovoltaic systems, where a DC current to AC current conversion is required, explaining the basic system parts, functionality, and configurations. In the following thesis an approach for a controlled converter for a DC power source is proposed, allowing voltage and phase manipulation required in order to synchronize and connect with the utility grid. The approach consists of using the Decoupled Double Synchronous Frame Reference Phase-Locked Loop (DDSRF-PLL) for synchronization and Space Vector Modulation (SVM) for the generation of the appropriate voltage level. These techniques are simplified, simulated for proofing, and implemented on a FPGA, Virtex II PRO Development Board, to ensure system flexibility and enabling easy future modifications. It also includes the necessary additional hardware for the system to be implemented: Voltage sensors, digital to analog converters, power interface, and the controlled converter circuits. Resulting in the combination of both techniques where the output from the DDSRF-PLL is used as an input for the SVM, resulting in a synchronized voltage with the appropriate amplitude. As an additional contribution, a Photovoltaic System’s Economic Feasibility Report (“Factibilidad Económica Para Sistemas Fotovoltaicos”) is included. A simulation software was developed in LabVIEW® for generating and analyzing the necessary data. This tool can be used to size a complete system and calculate the return of investment which can help the end-user make a better decision in the installation of a photovoltaic system array. With the use of this simulation software a set of spreadsheets with an economic analysis for representative cities in Mexico were created.

Current market requirements in industrial sector have motivated the development and adoption of digital manufacturing software tools for control systems design, training, and process optimization to validate and ensure the production system ́s programming control and automation equipment. This practice, known as Virtual Commissioning, emulates the real process behavior in a computer software environment. This technology represents an opportunity for education where the virtual emulation of real processes can be used to equip Control and Automation laboratories where students can test, validate, and debug their control and automation strategies, contributing to student formation and solving the need of having costly, real industrial machinery to reinforce the understanding of classroom theory, with practice. This is an excellent option for universities without enough resources, mainly in developing countries, where laboratories are commonly equipped with improvised home made systems that don ́t represent what students will face in an industrial environment. The development of a general procedure of 6 stages (3D CAD creation, Conversion process, Assembly process, Animation process and VRM Validation process) for the creation of an automation simulation virtual final application called Virtual Reality Machine (VRM) is proposed. This application is oriented to automation and control training by it usage for automation and control laboratory equipping. Whose features of performance and free licensing make possible that VRM can be applied to education. Where can contribute to student’s formation and can be adopted even for low resource educational institutions.Finally an equipping solution for automation and control laboratoriesis proposed.VRM capabilities, scope, usage, and contribution to student’s formation are presented.
