Modeling the operation of reclamation pumping stations during transition processes

Abstract

The hydropower and water management complexes include pressure systems with pumping stations that supply the required amounts of water to specified heights. Modern pressure systems are complex and varied. The control elements of these systems, primarily pumping stations, are continually becoming more complex and improved. In this regard, the costs for the construction and operation of pressure systems with pumping stations can be very high, therefore, the issue of choosing the best option when designing these systems becomes especially important. In this case, it is necessary to take into account transient processes, that is, transitions in operational conditions from one stationary mode to another. A significant change in these parameters leads to a violation of the normal operation of pressure systems, premature failure of their individual elements, and sometimes to accidents. Despite the accumulated experience in the construction and operation of pressure water supply systems, there are still no sufficiently general methods for calculating transient processes that ensure an increase in the reliability of structures. The paper presents the mathematical modeling of the calculation of transient processes in pressure water supply systems, the main directions for their further improvement are given.
