This article aims to discuss the monitoring and control technologies of pumped storage plants. It begins by analyzing the monitoring of parameters such as pressure and vibration. Subsequently, it introduces the monitoring systems for these data and the forms of fault diagnosis.
For pumped storage power stations that frequently switch between energy storage and power generation modes, Li et al. (2019) used the Zhanghewan pumped storage power station as an example to discuss the causes and impacts of local structural vibrations.
Zhang et al. (2020) coupled hydraulic systems with unit systems and proposed a transient model for multi-unit pumped storage systems. Analysis of the dynamic characteristics of the pumped storage system showed that transient performance could be improved by altering the movement patterns of guide vanes.
Finally, it explores the development trends of turbine monitoring technologies and fault diagnosis. Pumped storage hydropower plants employ a clever mechanism for energy conversion and storage, with their basic operation mode consisting of two phases: pumping and power generation, as illustrated in Figure 1.
Digital and intelligent monitoring systems are becoming more prevalent, including vibration monitoring, real-time analysis of performance parameters, and fault diagnosis, which greatly enhance the plant’s maintenance and operation capabilities (Wang, 2024; Xu et al., 2024).
The vibration monitoring of pump-turbines is a key aspect as the characteristics of vibration can reflect the health status of the internal structure of the turbine. During the startup phase of pumping operations at the Yixing power station (Jiangsu province, China), abnormal vibrations occurred in the guide vanes, leading to damage.
