ABB Advanced Power Electronics

STATCOM for Wind Farm to meet Grid Code reguirements.The ABB PCS6000 inverter meets all requirements related to technical design, efficiency, reliability, protection, and safety. The certification process involves a detailed evaluation of the PCS6000 test results, including functional testing, thermal operation testing, vibration testing, humidity and temperature testing, EMC testing, and protection testing.

PCS6000 is the first medium voltage wind power converter to obtain CGC certification. In addition to CGC, PCS6000 has also passed the DNV-GL GL-IV-2:2012 product certification.

STATCOM:
The STATCOM (STATic COMpensator) technology adds themissing functionality to wind parks in order to become gridcode compliant. The STATCOM as a pure static device withswitched passiveelementsprovides outstandingnoperformance for both steady state and dynamic operation.Especially, the fast dynamic voltage control and the behaviorduring balanced as well as unbalanced grid faults (fault ridethrough)allow meeting the stringent grid code requirements.Based on the medium-voltage converter platform widely usedfor industrial applications, ABB has successfully suppliedSTATCOMs to the wind power industry in order to integratewind parksgrids with demandingintoconnectionrequirements

Power Range: The PCS 6000 Wind has a power range of 4 MW to 12 MW and is suitable for large offshore wind turbines
