Abstract
Power quality (PQ) metering is an important part of the maintenance of modern electrical grids. Among different PQ indices, flicker severity coefficients Pst and Plt are measures of voltage fluctuation. In typical PQ analysers, the flicker measurement is usually implemented as a part of the meter’s algorithm performed by the main processor. Implementation of the IEC 61000-4-15 compliant flicker measurement algorithm requires a significant amount of computational power. To offload the processor subsystem this paper considers the implementation of the flicker measurement as an FPGA module. The measurement algorithm is developed and validated as a Simulink diagram, which is then converted to a fixed-point representation. Parts of the diagram are applied for automatic VHDL code generations and the classifier block is implemented as a local soft-processor system. A simple 8-bit processor operates within the flicker measurement coprocessor and performs statistical operations. Finally, an IP module is created that can be considered as a flicker coprocessor module. When using thy coprocessor, the only role of the main processor is to trigger the coprocessor and read results, while the coprocessor independently calculates the flicker coefficients.
