The Power System Simulator of Tomorrow

Power grids and systems are undergoing wholesale and seismic changes that dramatically increase their complexity. As we evolve from traditional, centralized power generation and distribution to 21st century grids featuring distributed energy resources (DER) and the integration of smart technologies, HYPERSIM gives engineers the tools to provide advanced real-time monitoring, control, and protection capabilities. Through a powerful real-time simulation platform featuring Hardware-in-the-Loop (HIL) testing, HYPERSIM models, prototypes, simulates, and tests power systems using a proven, robust and flexible suite of tools for development, integration and testing.

HYPERSIM Real-Time Simulation

HYPERSIM is state-of-the-art and extensively field-tested for both power electronics and power systems. Its open, flexible and scalable architecture and high-speed parallel processing enable the most demanding utilities, manufacturers and research centers to run faster, more realistic tests in order to meet the rapidly evolving requirements of the energy sector.
