What You Can Do

You can rapidly prototype pumped hydro storage systems by performing gross head calculations from topographic data, optimizing reservoir dimensions for target storage durations, and selecting appropriately sized pump-turbine units. Claude guides you through penstock diameter optimization, validates operating points against IEC and IEEE standards, and generates preliminary civil works estimates and equipment specifications ready for stakeholder review or financing submissions.

Features

Gross head and net head calculations from topographic surveys and elevation data
Reservoir sizing optimization balancing storage duration, embankment cost, and land footprint
Penstock diameter selection minimizing friction losses while controlling material costs
Pump-turbine technology comparison (fixed-speed, variable-speed, ternary units) with duty point verification
Preliminary civil works estimates including dam, spillway, and powerhouse dimensioning
Industry standard compliance checking (IEC 60041, IEEE 1020) with documented assumptions
Design scenario comparison enabling rapid trade-off analysis across 2-3 configurations
Technical specification generation for equipment procurement and vendor RFQs
