3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Wind turbine low voltage ride through capability lowvoltageridethroughcapabilityofwindturbine When the power grid fails or the disturbance causes a voltage drop, the wind turbine ensures that it does not fall off the network within a certain voltage drop range and time interval. The ability to continue running. 3.2 Wind turbine high voltage ride through capability highvoltageridethroughcapabilityofwindturbine When the grid fault or disturbance causes the voltage to rise, within a certain range of voltage rise and time interval, the wind turbine guarantees that there is no off-grid The ability to continue running. 3.3 Fault voltage generating device voltagefaultgenerator Based on the impedance/resistance-capacitor voltage division principle, test equipment that meets the test requirements for fault voltage specifications is generated at the test point. 3.4 Grid point/test pointpointofconnectionofwindturbine/pointoftestofwindturbine The point at which the fault voltage is generated is the connection point between the fault voltage generating device and the high voltage side of the step-up transformer of the wind turbine. 3.5 Active power recovery time recoverytimeofactivepower From the recovery of the grid voltage to the normal range, to the wind turbine output active power is restored to the actual wind condition corresponding to the output power required time. 3.6 Voltage drop voltagedip The effective value of the voltage at a certain point in the power system is temporarily reduced to less than 0.9 pu of the nominal voltage of the system, and returns to normal after a short duration. A phenomenon near the value. ......
