A review of dynamic models and stability analysis for a hydro-turbine governing system
(2021-07)
Article
Open AccessHydropower offers highly flexible, low-carbon generation that can be used to balance electricity grids with high levels of wind and solar penetration. This will become increasingly important as the energy transition unfolds. ... -
Diagnostics of a hydraulic turbine failure
(2022)
Conference report
Open AccessThis paper presents the failure analysis and diagnostic of a hydraulic turbine. Shortly after a maintenance revision the thrust bearing of the turbine was destroyed when the turbine was put into operation. The damaged ... -
Exploring the Regulation Reliability of a Pumped Storage Power Plant in a Wind–Solar Hybrid Power Generation System
(2021-09-17)
Article
Open AccessIn the coming decades, the proportion of wind–solar energy in power system significantly increases, resulting to uncertainties of power fluctuation in abundant wind–solar energy regions. The flexibility operation of Pumped ... -
Multi-objective optimization of a hydro-wind-photovoltaic power complementary plant with a vibration avoidance strategy
(2021-11-01)
Article
Open AccessHydropower has the advantages of quickly responding to load variability, which overcomes the unpredictable and unstable variabilities of solar and wind power. Therefore, such power generation can be combined into a ... -
Nonlinear modal interaction analysis and vibration characteristics of a francis hydro-turbine generator unit
(Elsevier, 2021-05-01)
Article
Open AccessThe Francis hydro-turbine generator unit (FHTGU) is a typical nonlinear system with the coupling hydraulic, mechanical and electric subsystems. It is a challenge to understand the reasons for its operational failures because ... -
The potential for photovoltaic-powered pumped-hydro systems to reduce emissions, costs, and energy insecurity in rural China
(Elsevier, 2021-09)
Article
Open AccessHomes in rural China often have access to water wells for domestic and agricultural use. Given the significant difference in height between the well water and the roof of the house, such an arrangement could be used as a ... -
Time-frequency domain characteristics analysis of a hydro-turbine governor system considering vortex rope excitation
(2022-01)
Article
Open AccessUnderstanding and simulating the dynamic characteristics of the hydro-turbine governor system is essential to guarantee the safety of the hydro-power systems. This study proposes a modification method of the water head at ... -
Transient analysis to air chamber and orifice surge tanks in a hydroelectric generating system during the successive load rejection
(Elsevier, 2021-09-15)
Article
Open AccessSurge tank is an essential device to control hydraulic transient of a Hydroelectric Gnerating Systems (HGS)s. However, various types of surge tanks differently reflect in reducing water hammer and improve performance of ...
