MODERN CONTROL ALGORITHMS FOR MULTI-PUMP STATIONS
In this article, we consider modern multi-pump systems, which includes a frequency electric drive. Here are presented the most commonly used algorithms for controlling pumping units: the algorithm connection of an additional pump unit; tripping algorithm additional pump unit; algorithm of transition to "sleep mode" pump installation in general. Here we indicate their shortcomings, which can lead not only to the occurrence of additional water hammers in the water supply system, but also to an ineffective operation in water supply system in general, including over-consumption of electricity.
