Abstract

DOI: 10.14684/intertech.13.2014.432-436 This paper presents a proposal for measurement, analysis and control of a three-phase power grid in four quadrants to identify the power flow using the described equations in VHDL, which are synthesized and implemented in FPGA. The results were validated using FPGA simulation techniques such as FPGA in-the-loop, co-simulation, embedded processing and the comparison with the experimental practical tests. Through the controller available resources it can minimize voltages and currents reading errors and delays, performing faster analysis and control response acting on the system with almost instantaneous decisions making. Index Terms - FPGA, VHDL, four quadrants, power flow, measurement.
