Energy Optimization
Multi-Pump Arrays & Variable Speed Drive (VSD)
Analyze parallel pump staging, series pressure boosting, and Variable Frequency Drive (VFD) speed modulation envelopes.
Module Overview
Modern pumping systems frequently utilize multiple identical pumps in parallel or variable speed drives to follow fluctuating process demands while drastically cutting electrical power consumption.
What You Can Do With This Module
Simulates parallel pump operation: computes combined flow rate at shared system head for 1 to 8 operating pumps.
Models series multi-pump configurations: sums head delivery for high-pressure deep well and cross-country transport duties.
Calculates Variable Frequency Drive (VFD) speed reduction curves using hydraulic affinity laws from 30 Hz to 60 Hz.
Identifies minimum continuous stable flow and maximum motor thermal limits at reduced speeds.
Visualizes intersection points between variable system curves and modulated pump speed curves.
