BERTA Test Bench
OPAL-RT’s BERTA test bench is a safe, reliable and portable test bench for speed governors, turbines, voltage regulators (AVR) and power system stabilizers (PSS). Equipped with a high-performance real-time simulator programmed with world-renowned RT-LAB software, the BERTA Test bench enables users to easily and comprehensively test real generating units in the power plant, synchronized and transmitting power to the main grid and/or on real controllers connected to a virtual generating unit in laboratory.
Turbine model parameters can change over time due to turbine wear and water head variation. By using test and measurement results, RT-LAB BERTA enables precise estimation adequate to turbine and speed regulator models. Increased precision also provides more accurate offline simulation and adjustment of speed regulator settings.
The RT-LAB BERTA approach increases precision with each subsequent test session, with results that are virtually identical to those expected from an actual islanded power system, but requiring only a fraction of the time required for traditional test methods.
