Methods for operating an inverter-based resource connected to a series-compensated transmission system

Abstract:

A method for operating an inverter-based resource includes monitoring a current magnitude in the inverter-based resource. The method also includes monitoring a voltage magnitude in the inverter-based resource. Further, the method includes comparing the current magnitude in the inverter-based resource to a primary current threshold. Moreover, the method includes comparing the voltage magnitude in the inverter-based resource to a voltage threshold. As such, the method also includes disabling switching of the switching elements of the power converter when the current magnitude increases above the primary current threshold and the voltage magnitude decreases below the voltage threshold to bypass the switching elements of the power converter until excess energy in the inverter-based resource is dissipated.
