Setting value downloading method and system of smart grid relay protection device

Abstract

The invention discloses a setting value downloading method and system. The setting value downloading method comprises the steps that setting value single-file transfer of a safe area III and a safe area I is conducted through a reverse safety isolation device, and setting value single-file transfer between the safe area III and the safe area I can be achieved; when the standard setting value does not exist in a database, initialization and downloading of the setting value are conducted through a relay protection setting value management system, and meanwhile proof-reading and confirmation can be conducted on downloading results. In this way, by means of the downloading method, automatic downloading and proof-reading of the setting value of a smart grid relay protection device can be achieved; compared with a traditional manual downloading method, the work efficiency is high, and the accuracy is good.

Description

technical field [0001] The invention relates to the technical field of power system scheduling automation, and more specifically, to a method and system for downloading a set value of a relay protection device of a smart grid. Background technique [0002] The setting value management of relay protection includes setting value calculation, setting value downloading, setting value checking, etc. Among them, the calculation of the setting value is generally performed by the relay protection management department. The calculation of the relay protection setting value needs to be considered to ensure that the relay protection device does not malfunction or refuse to operate under different operating modes and maximum load conditions of the power grid. A reasonable selection of the operating mode is It is one of the keys to improve the protection effect and give full play to the protection function. In the calculation of the setting value, it is necessary to consider the sensitiv...

Problems solved by technology

[0003] In the traditional substation operation and maintenance work, the process of setting and modifying the setting value of the relay protection equipment is as follows: After the relay protection professional management personnel set the setting value of the relay protection equipment through the offline calculation software, the setting list is sent by fax or mail. The mode is issued to the professional maintenance team of the relay protection of the grass-roots factory bureau, and the team members of the grass-roots unit drive to the substation to input the setting value into the relay protection equipment by manual entry, and manually check the running setting value on site. This working mode The execution cycle is long and requires a lot of manpower and material resources

[0004] From the traditional working mode of setting and checking the setting value, it can be seen that the management of the setting value is mainly manual work, which needs more manual participation to complete, the work efficiency is low, and the accuracy is poor
