Integrated approach to the upgrade  of booster pumping stations in Samara

Summary

The applicability of improving the reliability and energy efficiency of the water supply system of Samara is specified. The main me­thods and means of step-by-step implementation of the plan of upgrading booster pumping stations are described. The description of software and hardware system chosen for the implementation of the set task is presented. The data on the reduction of the total power consumption by 37 pumping stations is given. Frequency regulation of the pumping units operation provided for 40% reduction of the power consumption; the introduction of the adaptive regulating algorithm for the stations with parallel operation of several pumping units provided for 27% reduction of power consumption. The estimated reduction of power consumption with replacing pumping units after the introduction of the adaptive regulating algorithms was 18%. 8% reduction of the failure rate in the distribution network owing to the average pressure reduction in the distribution network and due to the improvement of the operational control efficiency by obtaining complete exact information on the process parameters in real-time mode was noted. The system introduction predetermined operating personnel downsizing and simplifying the organizational-technical measures for the maintenance of the pumping stations. The criteria expedient to be used in estimating the operation efficiency of the stations are indicated. The diagrams of the operation parameters of a number of upgraded pumping stations are presented. The recommendations on the further upgrade of the booster pumping stations on the Samara territory are quoted.
