What is a digital twin?

Q: What is a digital twin?

A digital twin is a virtual replica of a physical system that uses real-time data to mirror its state. It enables simulation, prediction, and testing of decisions without risk to the actual system.

A digital twin is a virtual copy of a physical system that uses real-time data to mirror its state. It allows simulation, prediction, and testing of decisions without risk to the actual system.

How It Works

A digital twin receives real-time sensor data from the physical system. It uses this data to keep a current model of the system's state. Operators can then run simulations on the twin — testing what happens if a part fails, if load increases, or if a maintenance action is taken.

Applications

Predictive maintenance — simulate equipment wear to test detection
Grid management — simulate load changes and generation dispatch
Process improvement — test operational changes before putting them in place
Risk assessment — simulate failure scenarios without real-world consequences

VLTHRLAB's Use

VLTHRLAB used digital twin simulation to test the MAD system, achieving 72.9% downtime reduction and 4.87x lower maintenance costs in simulation before any real-world use.
