Intelligent power distribution switch protection constant value setting system

Abstract

The invention relates to the technical field of power grid information, in particular to an intelligent power distribution switch protection constant value setting system. The network architecture ofthe system is characterized in that: the platform of the system adopts a convenient deployment and multi-level application mode, and integrally follows the plug-and-play principle; the system serviceis deployed in an enterprise intranet server, an enterprise intranet client can directly access the system service, and an extranet PC client and a mobile terminal access the system service through aVPN private network during field work. The system has the following beneficial effects, through providing the intelligent power distribution switch protection constant value setting system, the purpose of accurately and reasonably setting the protection constant value of the setting equipment can be achieved, enables the power distribution automation terminal and the protection device to achieve the functions of quickly removing a fault, reducing the power failure range and improving the power supply reliability of a power distribution network, provides reliable power supply guarantee for theproduction and life of residents, and brings good economic and social benefits to a company.

Description

technical field [0001] The invention relates to the technical field of power grid information, in particular to an intelligent power distribution switch protection setting value setting system. Background technique [0002] In recent years, the requirements for the power supply quality and reliability of the distribution network have become higher and higher. The State Grid Corporation has gradually promoted the construction of distribution network automation and improved the degree of distribution network automation. topic of increasing interest. [0003] At present, the full-time personnel set up the fixed value pairs based on table comparison, segmented estimation and estimation, and there are problems such as low efficiency, backward calculation methods and subjective errors of personnel are not easy to control. The relevant power distribution branch equipment parameters are submitted and the protection fixed value is reviewed. The release is mainly sent by mail. Duri...

Problems solved by technology

[0003] At present, the full-time personnel set up the fixed value pairs based on table comparison, segmented estimation and estimation, and there are problems such as low efficiency, backward calculation methods and subjective errors of personnel are not easy to control. The relevant power distribution branch equipment parameters are submitted and the protection fixed value is reviewed. The release is mainly sent by mail. During the execution, the paper carrier of the setting value record of the protection equipment is manually carried to adjust the setting value of the relay protection device on site. Protection fixed value calculation cannot be fully guaranteed in terms of efficiency and accuracy
