RTDS® Hardware-in-the-Loop Laboratory Testing

The Real-Time Digital Simulator (RTDS®) can interact with devices or systems under evaluation in real time to identify weaknesses and performance issues in equipment, relay settings, and modeling before they are put into service. This enables the owner or operator to resolve any issues discovered, preventing potential misoperations in the power system.

Testing with an RTDS system has proven significantly valuable in enhancing power system protection and control applications. RTDS is primarily developed and used for hardware-in-the-loop (HIL) testing of protective relays, digital controllers, and process control devices. This allows for performance evaluation and pre-commissioning testing under conditions that closely mimic real-world scenarios. HIL testing is commonly employed for prototype development and finalizing new application designs involving various digital control, protection, and measurement devices.

Advanced Automation and Testing Process Used by Quanta Technology

Quanta Technology has extensive experience in RTDS testing, based on our work with utilities and manufacturers worldwide. We have utilized a combination of testing automation and process enhancements to reduce the time required for RTDS testing while simultaneously improving the quality of the results. Our goal is to optimize the process to ensure all necessary tests are conducted as efficiently as possible.

Project Example: Impact of Inverter-Based Resources (IBRs) on the Protection System

Customers: Lonestar, National Grid, NYSERDA

Scope:

  • Model highly accurate IBR controls and the affected power system in RSCAD.
  • Perform HIL testing using RTDS to evaluate the impact of IBRs on various protection schemes.
  • Assess test results and provide prototype solutions.

Benefits of HIL testing for IEC 61850 verification:

  • Help eliminate protection problems before deployment.
HIL test setup for FP&L project

Project Example: Digital Substation Verification using RTDS HIL Testing

Customers: FP&L, Dominion Energy, LUMA Energy

Scope: Conduct HIL testing of the IEC 61850 system along with the power system by simulating contingencies and communication equipment failures, such as failures of switches, clocks, merging units, or communication links.

Benefits of HIL testing for protection scheme verification:

  • Analyze the efficiency, redundancy, and performance of the communication network.
  • Train utility employees to understand system operations.
  • Move most site acceptance test cases to factory acceptance tests through HIL testing.
