SIMULATION SOFTWARE FOR HYDRAULIC & ELECTRIC SYSTEMS ADJUSTABLE SPEED DRIVES

Introduction

The software package enables modelling, simulation and analysis of the power networks dynamic behavior, speed drives and hydraulic systems with arbitrary topology. The strength of the software leads to the possibility of including into the simulation:

Hydraulic circuits,
Electrical installations,
Rotating inertias,
Control/command systems,

with a very high degree of complexity for each part, ensuring to take properly into account all dynamics interactions.

Hydraulic and Electrical Transients
Water Hammer Calculation
Hydroelectric Systems
Power Network Stability
Complex Drives Control
