Multi-Objective Optimization of Nozzle Closing Strategies for High Head Pelton Turbines to Shorten the Nozzle Closing Time and Mitigate Water Hammer Effects

The rapid shutdown of high-head and large-capacity Pelton turbines equipped with long penstocks often induces severe water hammer effects, threatening the structural safety of the diversion system. Traditional linear or simple piecewise nozzle closing laws struggle to achieve an...
