Embodiment 1
[0026] A hybrid islanding signal transmission method of switching, digital and analog values, the method is to use the optimal transmission method between the converter station and a certain power station for the signal judged by the island discrimination device of a certain converter station, such as figure 1 shown, including the following steps:
[0027] Step 1: The islanding status and networked operation signals judged by the islanding identification device of the converter station are transmitted to the stabilizing device of the converter station in the form of switches through cables. The islanding identification device of the converter station is the master, and the islanding identification device of the power station is the slave.
[0028] The islanding identification device of the converter station mainly uses the switch operation status signal collected by itself and provided by the islanding identification device of the power station to determine whether the power s...
