Real Time Digital Simulator (RTDS) Studies
What are RTDS Studies?
Real Time Digital Simulator (RTDS) studies utilize advanced real-time simulation technology to test and validate power system behavior, protection schemes, and control systems. RTDS provides a hardware-in-the-loop testing environment that enables comprehensive analysis of complex power system phenomena.
RTDS technology bridges the gap between offline simulation studies and field testing, providing a safe, controlled environment for testing protection relays, control systems, and power electronic devices before deployment.
