Technical Field
[0001] This utility model relates to the technical field of water turbines, and in particular to a water-solar hybrid water turbine blade adjustment device. Background Technology
[0002] A hydro-solar hybrid power station integrates the photovoltaic (PV) output of a solar power plant into a hydropower station via a connecting line. Utilizing the strong regulation capabilities, high operational flexibility, and rapid start-up and shutdown characteristics of hydropower, it compensates for the instability of the PV output. The combined output is then fed into a substation to supply power to the system load. Through the complementary operation of PV power generation and hydropower generation, when PV output becomes unstable due to weather, diurnal variations, or other factors, the hydropower units can compensate for the instability of PV output through the rapid regulation characteristics of their turbines and the regulating capacity of the reservoir, thus improving power quality. Simultaneously, the integration of PV output effectively enhances the peak-shaving capacity of the hydropower units, thereby achieving complementary power generation between hydropower and PV.
[0003] Hydro-solar hybrid power plants emphasize utilizing the regulation capabilities of hydropower units and power transmission channels. The units operate in conjunction with large-scale photovoltaic (PV) renewable energy sources within the base, transmitting power while meeting the grid's power quality regulation requirements. This promotes the system's absorption of PV-generated electricity. When solar output accounts for a large proportion, if the external load remains constant, the turbines need to adjust the load significantly to ensure total output power. In actual operation, the demand for stable operating range of the hydropower turbines in this hybrid system exceeds existing specifications; that is, the turbine design of the power plant needs to broaden the stable operating range of the unit's output. Furthermore… Under the conditions of hydro-solar hybrid operation, axial-flow turbines will face frequent load changes, and the operating conditions are more severe than those of conventional turbines. Hydropower stations must have rapid load adjustment capabilities to respond more quickly to load changes. Frequent load changes require frequent blade movements, and the number of movements of the blade transmission structure increases exponentially compared to traditional axial-flow propeller units. This not only tests the flexibility of the regulation system but also significantly increases the wear of the transmission mechanism, leading to a significant increase in the fatigue of related components. Therefore, a blade regulation device for hydro-solar hybrid turbines is needed. Utility Model Content
