Abstract :
This paper addresses approaches to improve the power consumption indexes of multi-pump systems. Focus on optimization of productivity, adjustment of the number of running pumps and starting-stopping criteria in multi-pump systems. Method of the productivity adjustment based on the reduction of motors starts-stops is proposed. The method includes prediction of the future state of the system and reduction of the start/stop operations on expense of short time widening of operation limits. Reduction of pumps starts and stops contribute into the stable power quality in the network.
