WindGuard Certification GmbH has signed a memorandum of understanding (MoU) with South Korean power converter manufacturer Plaspo for Korean grid. Both companies will work together on the development and construction of a measurement container for fault-ride-through (FRT) tests.

The MoU signifies the start of a comprehensive campaign by the South Korean government to optimise its grid infrastructure and expand their use of renewable energy.

The campaign includes the enforcement of more rigid grid codes and the implementation of obligatory measurements and certification. WindGuard Certification and Plaspo will supply the necessary measurement equipment.

In the last two years, WindGuard Certification has successfully delivered three units of its new generation of FRT test containers.

WindGuard Certification test laboratory head Damian Slowinski said: “The USP of our containers, its compact build, the simple and safe appliance, as well as the reduced loads on the public grid during testing apparently appeal to customers outside of Europe as well.

“We are happy to support Plaspo with our expertise in developing and building the first FRT container for the South Korean 33kV grid.”

FRT containers simulate artificial fault conditions at grid connection points. They are used to prove the capabilities of grid stabilisation of a wind turbine and its adherence to the medium-voltage grid guidelines. WindGuard Certification’s FRT container can simulate over voltage and voltage drops in medium-voltage grids, according to the current FGW TR 3 and IEC61400-21-1.
