Abstract

In paper the analysis of the two strategies of recording the parameters from electrical power system is presented. The strategies differ in the ways of synchronization between the functional blocks of measuring system. The paper presents the time dependencies between operations carried out during the registration of data from the electrical power system, stored on USB flash drive. The successive stages of data registration are shown, starting from power system signals conversion into digital form, by data gathering and processing in the DSP and then sending it to the FPGA, transferring to memory of the GPP, and finally, storing on USB flash drive. The way of synchronization of data readout from the FPGA to the GPP is crucial for the instrument operation, for the continuity of visualization and recording of data from power electrical system.
