Study of Hydraulic Disturbance Test and Predetermination of Pumped-storage Unit

Hydraulic disturbance analysis is an important part of hydraulic transient process analysis of hydropower projects. This paper introduces the hydraulic interference of some power plant systems in different network operation mode and the results of simulating calculation under the same boundary conditions with that of hydraulic disturbance test cases. It forecasts the controlling extreme conditions, providing some reference for the safe operation of power station and the design and calculation of other similar projects.
