Abstract

A total of 87 test items has been completed in the system commissioning of Nan'ao VSC-MTDC Demonstration Project.The power step tests show that the system is sensitive to the reactive or active power step.The active power inversion test, wind power grid test and operation mode changeover test show that Nan'ao project can operate steady in all kinds of system conditions.The wind power LVRT test shows that the project has strong fault ride-through capability on AC grid failure.The DC system fault test shows that DC protections at each station have tripped correctly, their control and protection functions are proper.It is verified by the commissioning that the related primary equipment and secondary equipment can completely meet the design requirment, and the engineering functions and performance of the equipment are in agreement with the design specification.
