Description

Method for executing and testing safety measures of relay protection automatic device of intelligent station

Technical Field

The invention relates to the field of automatic relay protection devices of intelligent stations, in particular to a method for executing and testing safety measures of an automatic relay protection device of an intelligent station.

Background

At present, relay protection tests are generally single-function tests based on a protection principle, system tests at a device level need the participation of testers in the whole process, and test items are limited. Because every test link of whole test procedure all needs artifical the participation, work efficiency is not high, has higher requirement to tester's level moreover, also often appears the human error when the large amount of test data in the arrangement report.

Disclosure of Invention

The invention aims to provide a method for executing and testing safety measures of an automatic relay protection device of an intelligent station, so as to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

a safety measure execution and test method for an automatic relay protection device of an intelligent station comprises the following steps:

1) importing configuration information, wherein various parameters of each intelligent electronic device IED in the intelligent station are contained in a system configuration description file SCD and an IED configuration description file CID of the intelligent station, acquiring various parameters of each intelligent electronic device IED in the intelligent station through the SCD file and the CID file, acquiring constant value information through an MMS network, and uploading the information to an automatic test control center for testing;

2) the automatic test control center acquires the configuration of the whole station through the introduced SCD file and CID file to obtain the data flow direction of each electronic device, including SV flow direction and GOOSE flow direction, builds a whole station model through the SCD file and the CID file, generates a database to obtain a plurality of different test types, forms different test schemes, and sends the test schemes to the line protection module and the automatic test system module for testing;

3) the line protection module sends information to the relay protection automatic device through an MMS network, then sends SV messages to the relay protection automatic device, the line protection module automatically adjusts the output SV messages to ensure that the SV messages are respectively 120% or 70% of a protection fixed value, automatically records action time, and sends out an abnormal alarm of a test item of the relay protection automatic device and stops a test if the tested device does not act correctly, and simultaneously uploads a test result to the terminal display module;

4) the automatic test system module is used for sending a test scheme to be tested to the automatic test system module by the automatic test control center, starting to test the test scheme, testing according to the fixed value information obtained by the MMS network and uploading a test result to the terminal display module;

5) and the terminal display module is used for displaying the test result to the staff.

Compared with the prior art, the invention has the beneficial effects that: through the matching of the automatic test control center and the automatic test system module, each electrical element of the relay protection automatic device of the intelligent station can be automatically tested, the test result is relatively accurate, and errors can not occur; through setting up the line protection module, can judge the electric elements who measurands to prevent the damage of electric elements appearing when the test.

Detailed Description

The technical solution of the present invention will be described in further detail with reference to specific embodiments.

Example 1

Referring to fig. 1, the present embodiment provides a method for executing and testing safety measures of an automatic relay protection device in an intelligent station, including importing configuration information, an automatic test control center, a line protection module, an automatic test system module, and a terminal display module.

The configuration information is imported, various parameters of each intelligent electronic device IED in the intelligent station are contained in a system configuration description file SCD and an IED configuration description file CID of the intelligent station, various parameters of each intelligent electronic device IED in the intelligent station are obtained through the SCD file and the CID file, constant value information is obtained through an MMS network, and then the information is uploaded to an automatic test control center for testing.

The automatic test control center obtains the configuration of the whole station through the introduced SCD file and CID file, obtains the data flow direction of each electronic device, including SV flow direction and GOOSE flow direction, builds a whole station model through the SCD file and the CID file, generates a database, obtains various different test types, forms different test schemes, and sends the test schemes to the line protection module and the automatic test system module for testing.

And the line protection module sends information to the relay protection automatic device through an MMS network, then sends SV messages to the relay protection automatic device, automatically adjusts the output SV messages to ensure that the SV messages are respectively 120% or 70% of the protection setting value, automatically records the action time, and sends out an abnormal alarm of a test item of the relay protection automatic device and stops the test if the tested device does not act correctly, and simultaneously uploads the test result to the terminal display module.

And the automatic test control center sends the test scheme to be tested to the automatic test system module, the automatic test system module starts to test the test scheme, tests according to the fixed value information obtained by the MMS network, and uploads the test result to the terminal display module.

And the terminal display module is used for displaying the test result to the staff.

While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
