WAYS FOR ENERGY SAVING IN PUMPING PLANTS FOR MELIORATION AND IRRIGATION SYSTEMS
DescriptionProblems concerning energy saving become more urgent in the connection with permanent increasing of electricity price and enactment of the law regarding energy efficiency and energy saving. Regulated electric drive has been using widely for energy saving within pumping plant. Appropriate equations were carried out for adequate regulation of technology process of water travel and energy supplying. The analysis of criterion function for optimization and efficiency factor for specific elements as well as whole system makes it possible to find out the optimal system parameters and define energy saving work conditions
