Embodiment Construction
[0023] The process and principle of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] The present invention provides a method based on power distribution network topology protection, comprising the following steps:
[0025] (1) A distribution network topology is formed between distribution automation terminals (DTU: distribution terminal unit or FTU: feeder terminal unit). In this embodiment, any distribution automation terminal is designed as a distribution automation terminal only with its adjacent nodes. The terminal constitutes a topology structure, and a horizontal communication link is adopted between each distribution automation terminal and the distribution automation terminal of the adjacent node;
[0026] first as figure 1 As shown, it is a typical grid structure of a power distribution network between substations A and B. For the convenience of description, the following definition...
