Hardware-in-the-loop testing of power system protection schemes

Test, optimize, and verify the performance of complex protection systems.

PTI Consulting offers protection hardware-in-the-loop tests in the power system, simulated in real time to optimize and verify protection device settings.

Protection and control devices work with the simulator in a closed loop to carry out complex switching sequences of relays, measuring equipment, and controllers. In customer workshops performed during testing, you can expand your capabilities to operate the devices and broaden your expertise in analyzing disturbances and protection responses. Detailed, highly tailored documentation can then be used for further reference and analyses during actual power system operation.

Wide area monitoring, protection and control testing in real time

Increase reliability and verify the performance of control and protection devices for special power system protection schemes.

The higher penetration of renewables and the increase in stability interactions lead to the need for automatic schemes that initiate corrective actions in the system to maintain security. Such schemes are system critical, because no operator can react in this time frame. The proper functionality of such Wide Area Monitoring, Protection and Control (WAMPAC) systems is essential for future grid operation. In our laboratory, we have all the key building blocks available to test such systems efficiently with high dependability. WAMPAC requires detailed real-time testing to ensure correct behavior in the field.

Controller hardware-in-the-loop testing in microgrids

Optimize and verify the performance of control devices in a real-time simulation environment.

The increasing penetration of renewables and the ongoing digitalization in power systems make it necessary to have new operation and control concepts for the power system.

Besides the conceptual design and detailed studies in simulation, PTI Consulting experts test controller hardware in a closed loop. In our laboratory, we have detailed simulation environments available to test and develop new control schemes for transmission and distribution systems, as well as microgrids. Within such tests, proof-of-concepts can be realized that support you in understanding and tuning new control ideas.

Customized power system protection workshops

Expand your competencies in protection schemes and relay functionality with hands-on workshops in our RTDS lab.

Unlike with sudden disturbances in real operation, during the RTDS tests the information of the fault type and its characteristics is known. This allows the user to understand the expected chain of events and the response of the protection system.

In our hands-on workshops, we perform hardware-in-the-loop tests based on your actual network conditions. Protection engineers are trained to expand their knowledge of the operating principles of protection devices and their experience regarding power system protection operation, as well as its interaction with the secondary and primary equipment.
