Embodiment 1

[0056] A GOOSE-based distributed power distribution method provided by an embodiment of the present invention, such as figure 1 As shown, in this embodiment, steps S0-S3 are included:

[0057] S0. Set a corresponding priority for each transfer path in advance, and divide a corresponding test time period according to the priority.

[0058] In this embodiment, the transfer path is associated with the test time period, and the automatic test of the transfer path with multiple priorities is realized by directly using the setting of the time node, and the optimal transfer path is screened to select the acceptable Incoming optimal transfer path.

[0059] S1. The power distribution terminal regularly acquires line characteristic parameters, including steps S11-S13:

[0060] S11. The power distribution terminal regularly collects the load current value and voltage value of the corresponding line switch;

[0061] S12. Calculate and obtain a corresponding load current value according...

Abstract

The invention relates to the technical field of power grid power distribution, and provides a GOOSE-based distributed power distribution method and a power distribution automation terminal. The line health state between two adjacent power distribution terminals can be directly obtained according to the communication state between the two adjacent power distribution terminals. After a node fault occurs, the line characteristic parameters corresponding to transfer paths are automatically obtained by taking the line characteristic parameters of a power supply line switch which works normally before the fault occurs as reference variables, and are substituted into a preset transfer condition, and during transfer, the transfer paths are tested in sequence according to a preset priority condition, and better transfer paths are tested first according to the priority setting, thereby providing an optimal power supply for the power distribution terminals. A transfer path can be simply and quickly connected to an adjacent power distribution terminal by controlling an interconnection switch connected with the transfer path to be switched on, other normal power supply paths are switched over,and normal power utilization of residents can be guaranteed before the fault node is not repaired.

Description

technical field [0001] The invention relates to the technical field of power grid distribution, in particular to a GOOSE-based distributed power distribution method and a distribution automation terminal. Background technique [0002] Distribution automation technology is an important technology serving the transformation and construction of urban and rural distribution networks. Distribution automation includes feeder automation and distribution management systems. Communication technology is the key to distribution automation. In recent years, the scale of my country's power grid has been continuously expanding, and the automation level of the power grid has been continuously improved. Therefore, intelligent distributed distribution network automation technology has been widely used. However, with the rapid development of today's social economy and technology, the public's requirements for power grid distribution are also increasing, and higher requirements are put forward...
