Intelligent distribution type FA fault processing method based on master station standby

Abstract

The invention provides an intelligent distribution type FA fault processing method based on master station standby. The intelligent distribution type FA fault processing method comprises the following steps: (1) defining a static topological model and a dynamic topological model of a distribution circuit as self-adapting model foundations for distribution circuit topology change; (2) completing generation and issuing of dynamic operation topology through a master station and the topological model interactive mechanism of a distributed FA; (3) when the static topology of the distribution circuit is changed, realizing the static topology self-adaption of the distribution circuit according to a static topology self-adaptive algorithm of the distribution circuit; (4) when the distribution circuit breaks down, making the distributed FA enter a fault isolation program, and meanwhile completing topological updating of the distribution circuit according to the self-adaptive algorithm of the distribution circuit topology change caused by fault isolation; and (5) after a system entering a load transfer supply program, completing the topological updating of the distribution circuit according to the self-adaptive algorithm of the distribution circuit topology change caused by load transfer supply. According to the method, cooperation of the distributed FA and distribution master station faults is realized.

Description

technical field [0001] The invention relates to the field of electric power system and automation thereof, in particular to an intelligent distributed FA fault processing method based on master station backup. Background technique [0002] Feeder automation can be divided into centralized FA and distributed FA according to different working mechanisms. Centralized FA relies too much on the accuracy of the global information of the master station, which has a greater impact on power supply reliability; while distributed FA relies on the coordination and cooperation of adjacent terminals. Actions are taken on fault location, isolation and recovery, which can realize rapid fault isolation and self-healing. In the current intelligent distributed FA application, there are still great deficiencies in its interaction with the power distribution master station and its collaborative processing capabilities, mainly as follows: [0003] (1) The self-organizing network capability of th...

Problems solved by technology

[0003] (1) The self-organizing network capability of the primary equipment of the intelligent distributed FA is poor: because the accuracy of its action is closely related to the topology of the distribution line, when the topology of the distribution line changes, there is no right to install it in the distribution automation terminal. The means and methods for automatic update of the topological model of the line, that is, the distribution automation terminal cannot realize the self-organizing network function when the topological structure of the distribution line changes;

[0004] (2) The interactive ability between intelligent distributed FA and distribution automation main station is poor. In the current application process of intelligent distributed FA, the information interaction and mutual cooperation between intelligent distributed FA and distribution automation main station have not been properly resolved. The intelligent distributed FA and the centralized FA of the distribution automation master station operate independently, lacking unified coordination capabilities
