A kind of distribution network fixed value automatic setting method, device and distribution network system

Abstract

The invention discloses a power distribution network constant value automatic setting method and device and a power distribution network system. The method comprises the following steps: firstly, configuring protection types, constant value items corresponding to each protection type, and a calculation principle and a value taking principle corresponding to each constant value item; when an automatic setting instruction for a certain switch is received, obtaining the protection type of the switch, the parameter values of all switches on an outgoing line where the switch is located, and the upper-level and lower-level topological relation of the switches; obtaining to-be-set constant value items according to the protection type, and obtaining a calculation principle and a value taking principle corresponding to each constant value item; and for each constant value item, determining the value of the constant value item according to the corresponding calculation principle of the constantvalue item, the parameter information of all the switches and the corresponding value taking principle. By the adoption of the method, when the calculation principle is changed, the calculation principle is modified through the visual interface, maintenance cost is reduced, a user can define configuration by himself or herself, and operation is easy.

Description

Technical field[0001]This disclosure belongs to the field of power switch protection, in particular, to a distribution method, device and distribution network system for distribution network.Background technique[0002]The operation and maintenance process of the distribution network needs to protect the personal safety of the power distribution network equipment and the relevant personnel through the set value, that is, by setting the value of each distribution management device in the distribution network to avoid security incidents. In practical applications, for devices to be set, it is necessary to consider the upstream and downstream device parameters on the same line. For each set, multiple tuning rules must be met.[0003]The automatic tuning method of the current distribution network, mostly based on the principle of the local current user, directly through the computer code, however, although the value is automatically tessed, there is the following issues:[0004]When the user'...

AI Technical Summary

Problems solved by technology

[0004] When the user's setting principles change, or there are differences in the setting principles in other regions, since the user is invisible to the algorithm, the adjustment of the algorithm depends entirely on the developer. The developer needs to understand the user's needs and make modifications. The time cost of modification will be high; every change of the algorithm requires repeated communication between developers and users, which makes the maintenance cost of the enterprise high for the software;
