Efficiency of the systems of energysaved control circulation pumps power station

Abstract

In article are considered actual questions of the reduction of the consumption to electric powers on own necessities heat power station by way of energy-saved control. Is it for this purpose organized analysis of the experimental energy features circulation pump OP-2-145 heat power stations Zmievskaya TES, as follows dependencies of the pressure, comsumed to powers, coefficient of efficiency and losses to energy in circulation pump from frequency of its rotation, consuption and degree of the closing adjusting bolts. On base experimental given are revealled possible reserves energy-save under automated of energy-saved control circulation pumps. Possible economic effect is shown when use different algorithm control circulation pumps, including choke regulation, frequency step-like regulation and frequency fluent regulation. The certain law of control, under which loss in circulation pump will be minimum.
