The construction and influencing factors of the excitation source are analyzed. Modeling strategies with multiple excitation sources are discussed. Hydraulic oscillation is a common phenomenon in pumped storage power stations (PSPS). The presence of hydraulic oscillation can induce fluctuations throughout the PSPS system.
Introduction The pumped storage power station (PSPS) is crucial for maintaining grid stability and effective energy management. PSPS systems mitigate the intermittency of renewable energy sources and provide a means to balance supply and demand within the electrical grid [, , ].
Furthermore, when the system experiences oscillation, the bypass switch is opened, and the Rc0 is connected to the system in series, which increases the equivalent resistance of the grid network to suppress the occurring oscillation. Figure 16.
Sustained hydraulic oscillations can lead to structural failures within the system [11, 12] and pose a significant threat to the safe operation of both the plant and the power grid, particularly when the frequency of a disturbance source approaches the natural frequency of the PSPS system.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
