Hydraulic Oscillation Analysis of the Hydropower Station with an Equivalent Circuit-Based Hydraulic Impedance Scheme

The concept of hydraulic impedance is widely used for periodic or oscillating flow scenarios in applied transients. This paper proposes an equivalent circuit-based discrete model the system power station. circuit established by analogy between water hammer wave propagation pressurized pipes and electromagnetic conductors. at a given location obtained calculating total specific series parallel circuits from one end to other. In addition, numerical solution process obtain natural frequencies via proposed designed detail. Furthermore, oscillation characteristics pipelines hydropower station are investigated. variation trends decay coefficients different orders influence turbine on discussed, respectively.
