CONTROL OF A RENEWABLE ENERGY POWER PLANT TO RESUME NORMAL OPERATION FOLLOWING A FAULT

摘要

There is provided a method (500) for operating a renewable energy power plant (12) comprising a plurality of renewable energy generators (14), the method (500) comprising: calculating (502) a rate of change of reactive power reference level for transitioning between a present reactive power reference level, output by a reactive power controller (206), and a target reactive power reference level, the target reference level being suitable for normal operation of the renewable energy power plant (12); and, following a fault on a power network to which the renewable energy power plant (12) is connected, dispatching (506) a control signal for controlling the renewable energy power plant (12) to generate or consume reactive power at the calculated rate of change to transition the reactive power level of the renewable energy power plant (12) to the target reactive power reference level.
