Abstract :
The present paper describe an original program elaborate by authors in order to analyze the economic and energetic efficiency of using variable speed driven for turbo-pumps. The input dates of the program are represented by the parameters circuit hydraulic pump, the pump characteristics, motor drive, static frequency converter circuit and power supply. The program realise a comparative analysis of electricity consumption for flow through valve adjustment and changing speed for a curve given technical task. Starting from energy savings and the equipment cost it can be determined the payback of the investment. The paper presents a case study.
