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;

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] The present disclosure belongs to the technical field of power switch protection, and in particular relates to a method, a device and a distribution network system for automatically setting a fixed value of a distribution network. Background technique [0002] The operation and maintenance process of the distribution network needs to protect the personal safety of the distribution network equipment and related personnel through fixed value setting, that is, to avoid safety accidents by setting the fixed value of each distribution management device in the distribution network. In practical applications, for the equipment to be set, the upstream and downstream equipment parameters on the same line need to be considered. For each set value, multiple setting rules need to be met. [0003] The current automatic adjustment methods of the fixed value of the distribution network are mostly based on the local current user's setting principles and implemented directly ...
