Prediction and analysis of power consumption and power loss at industrial facilities

THE PURPOSE. Conduct a study to improve the reliability of forecasting magnitude power consumption and losses at an industrial enterprise. METHODS. Methods are used determine predict parameters electricity facilities. RESULTS. To clarify losses, it is proposed use coefficients that take into account type load curves show ratio values sum squares currents (powers) variable curve average (powers), is. during operation according uniform schedules (K graph ), as well coefficient takes topology circuit top ). The radial main circuits networks was carried out were determined using coefficients. equivalent resistances shop various topologies calculated. operational data section workshop network given. It revealed with constant technological process, increase in resistance due contacts switching devices installed on lines. value estimated supply parameter resistance. At same time, error calculating relation actual annual amounted 2,63%. According retrospective circuit, possible predicted this change These characteristics scheme recommended be assessment electricity, which will for
