R&D Nester at the “New HIL Trends in Protection Systems” webinar


R&D Nester attended the "New HIL (hardware in the loop) Trends in Protection Systems" webinar, promoted by OPAL-RT, which took place on 7 June.

Representing the Centre for Energy Research and Development of REN and State Grid was R&D Nester's researcher and REN's employee, Ricardo Cartaxo, who shared his experience in real-time simulation with the "HIL testing of Protection, Automation and Control (PAC) systems" presentation. The presentation sought to illustrate the advantages of using a Real-Time Power System Simulator (RTPSS) to test a PAC system. An RTPSS is designed to simulate a power system, enabling the execution of tests in closed loop (HIL).

In this test, the RTPSS can be used to simulate faults (short circuits) in the power grid, in order to evaluate the PAC system's performance. With the simulator's resources, it is also possible to automate tests using the TestView, enabling the convergence analysis of the test's results.

At the meeting, where awareness was raised to the trends in HIL simulation and testing in Protection Systems, there were presentations and live demos, seeking to show how these technologies can help companies reduce risks, costs and the total time required to identify faults in the power grid, enabling testing of complex protection systems and more efficient monitoring.
