Research On Cascade Speed Regulation Of Circular Pump Motor In Heat Supply Network Of Thermo-electric Plant Heating Station

In this paper, North United Power Baotou power plant of heating station#1circulation pump motor energy saving transformation project is rely on, on the water (the wind) pump equipment energy saving principle was analyzed, in view of the wide application of high voltage frequency conversion speed regulation, internal feedback cascade speed control, variable speed control are analyzed. Through reliability, advanced and economic aspects of comparison, North United Power Baotou power plant of heating station#1circulation pump motor suitable for modern high frequency chopping internal feedback cascade speed control technology for energy-saving reconstruction.This article on Baotou power plant heating system of heating station are introduced, the speed regulation of high frequency chopping internal feedback cascade system were studied in detail analysis; and in the completion of the transformation of the entire system was monitored, on the overall system performance testing, the energy saving effect of analysis of. According to the analysis results, after the transformation of the high frequency chopper cascade speed regulation system is running stable and reliable, has obvious energy saving effect, project implementation of the target is finished smoothly.
