| Abstract: | A sustainable development plan is presented for the model selection of power distribution terminal equipment,which is operating under open-loop operation mode of 10kV urban power distribution network. The electromotion distribution switch,equipped with digital radio transceiver,realizes the fast fault clearing and isolation of distribution line pilot protection by self-judgment according to the fault current and remote blocking signal. When equipment works abnormally,the re-closing operation can be used to increase the reliability of power supply. |
