The invention discloses a multicasting-based power distribution network WAMS communication protection and feeder automation method. The method is characterized in that a multicasting-based power distribution network WAMS communication model is set and used for bearing a power distribution network WAMS communication service; by adopting multicasting communication, the communication reliability of the power distribution network WAMS is improved; a multicasting-based power distribution circuit PDC and a power distribution circuit PMU are set, and intelligent distributed feeder automation is achieved; a multicasting-based power distribution circuit PMU and a distributed power access controller are arranged, and distributed power grid-connected protection is achieved. The method can effectivelyenhance the power distribution network WAMS communication reliability, shorten fault positioning, fault isolating and perfect region power recover time, improve the reliability of feeder automation,and reduce the risk caused by distributed power grid connection to safety running of the power distribution network.
Description
technical field [0001] The invention relates to a communication mode of distribution network WAMS and a feeder automation method, in particular to a multicast-based distribution network WAMS communication protection and feeder automation method. Background technique [0002] Distribution network WAMS (Wide Area Measurement System, wide-area monitoring system) is a wide-area monitoring system applied to the distribution network. It adopts the synchrophasor measurement technology and arranges the distribution line PDC (Phasor Data Concentrator, phasor data concentrator), distribution line PMU (Phasor Measurement Unit, synchronized phasor measurement unit) is arranged in each section of the distribution line to realize real-time high-level monitoring of distribution line synchrophasor and distribution network main data rate collection. [0003] The power distribution line PMU should have the functions of synchrophasor data collection, upload and time synchronization of the tra...
