A Way to Measure Power-Quality Indices in Devices for Monitoring Processes That Take Place in Overhead Power-Transmission Lines

摘要

A generalized structure of an algorithm for measuring the power-quality indices is examined. The specific features of the algorithm's blocks and possible ways to interpret it for different purposes and soft- and hardware abilities are shown. Ways to test the algorithm at every stage of development (from verification of the mathematical model to software debugging) are described. We analyze the algorithm's operation in the LabView environment for measuring power-quality indices. A multifunctional device for measuring power quality in accordance with GOST (State Standard) 30804.4.30-2013 is presented. Bench tests of the multifunctional device under different operating conditions and when carrying out different functions in the frame of one soft- and hardware platform are carried out.
