ABSTRACT

Energy optimisation of multi-pump stations requires pump-specific energy, yet many installations measure only total station flow. This simulated feasibility study reconciles discharge pressures, pump electrical powers and station flow against a calibrated 1D hydraulic model to identify degradation. Controlled head-curve and pump-efficiency degradations were introduced into one pump of a three-pump intake model. Calibration signatures separated at 45.9°, and validation cases were estimated as closure coefficients indicating mechanism and approximate magnitude. Closure magnitude increased with the affected path’s simulated specific-energy deterioration, providing proof-of-concept evidence for identifying degraded pump paths without branch flow as an estimator input.
