| 摘要 |
The invention relates to a method for detecting load-shedding of an inverter (22) connected to a power grid (3), comprising at least the steps of determining the time derivative of the voltage unbalance factor (RoCoVUF) between phases output by the inverter; determining the rate of change of frequency (RoCoF) of the voltage output by the inverter; multiplying (43) the two values; and comparing (46) same to a threshold (TH). |
