The system has the advantages that the distribution network relay protection constant value can be automatically calculated through the distribution network automation module, the protection setting value setting calculation module and the setting calculation platform, a calculation book and a constant value list are automatically generated, and the problem that distribution network setting calculation automation cannot be achieved due to modeling, setting complexity and the like of a distribution network is solved; distribution network personnel are liberated from tedious manual calculation, repeated work and manual calculation errors of the distribution network personnel are reduced, a technical foundation is laid for intelligent setting of the distribution network, and the automatic set value setting calculation platform can be provided for relay protection distribution network setting calculation personnel.

Description

technical field [0001] The invention relates to a relay protection setting calculation and data management system of a distribution network system. Background technique [0002] With the rapid development of the national economy, users have put forward higher requirements for the reliability of power supply of medium and low voltage distribution networks. The operation of distribution network needs to ensure reliable power supply time, reduce grid faults and their impact, which makes the calculation of relay protection setting of distribution network more and more important. In power systems at home and abroad, the setting calculation tool has gone through a development stage from low-level to high-level, realizing the automation of the whole process of setting calculation, providing a convenient and intuitive human-computer interaction interface, improving the organization and management mode of data and information, and becoming a new generation Set the direction of compu...

Problems solved by technology

[0003] The current distribution network relay protection work is characterized by frequent changes in the distribution network operation mode, complex wiring methods, and more T-connections and T-connections. When using the relay protection setting and management methods for high-voltage power grids, the workload is heavy. , and the accuracy and completeness of equipment parameters cannot be guaranteed. At the same time, due to the wide variety of distribution network protection devices, there is no specification for power network protection devices like high-voltage levels. The workload of distribution network setting staff is large and the work efficiency is low. , and the error rate is also high
