Embodiment 1

[0024] An embodiment of the present invention provides a method for automatically testing the fixed value of a relay protection device, such as figure 1 Shown, the concrete steps of testing method of the present invention are as follows:

[0025] Step 101: receiving a test request, editing the test template and report template of the relay protection device;

[0026] Wherein, the test request may be a test request input by a user (that is, a tester) through a computer. After receiving the test request, the computer edits the test template and report template of the relay protection device, and compiles the test template and report template Stored in the database for subsequent test procedure calls.

[0027] Step 102: Generate voltage and current values ​​according to the operation setting and test template of the relay protection device;

[0028] After the computer receives the test request from the user, it generates voltage and current values ​​(that is, fault analog quant...

Embodiment 2

[0182] The embodiment of the present invention also provides a relay protection device fixed value automatic test system 5, such as Figure 12 As shown, the testing system 5 includes: a template editing unit 51 , a voltage and current value generating unit 52 , an analog data output unit 53 , a protection information acquiring unit 54 and a test result generating unit 55 .

[0183] During the test, the system receives the test request input by the user through the template editing unit 51, and edits the test template and the report template of the relay protection device; The test template generates a voltage and current value; after obtaining the voltage and current value generated by the voltage and current value generation unit 52, the analog data output unit 53 controls the relay protection tester to output a voltage and current simulation to the relay protection device according to the voltage and current value. quantity data; the relay protection device generates protect...

Abstract

The invention provides a relay protection device fixed value automatic test method and system. The method includes: receiving a test request, and editing a test template and a report template of a relay protection device; generating voltage and current values according an operating fixed value of the relay protection device and the test template; controlling a relay protection tester to output voltage and current analog quantity data to the relay protection device according to the voltage and current values; obtaining protection action information and/or protection action message information generated by the relay protection device according to the voltage and current analog quantity data; and testing according to the protection action information and/or protection action message information, and generating a test result. According to the relay protection device fixed value automatic test method in the invention, a test is carried out in combination with a protection fixed value generated by the relay protection device, the test of the protection device can be completed reliably, efficiently and automatically, and a test report can be generated according to the test result, so as to satisfy an actual need for improving work efficiency of field debugging.

Description

technical field [0001] The invention relates to a testing technology of a relay protection device, in particular to a fixed value automatic testing method and system of a relay protection device. Background technique [0002] The safe and stable operation of the power grid is the premise and basis for realizing the reliability of power supply. As the first line of defense of the power system, relay protection is one of the essential devices to ensure the safe and stable operation of the power grid and equipment. In various power plants, substations and user power supply systems, a large number of relay protection devices are used to realize various protection functions. According to the "Inspection Regulations for Relay Protection and Power Grid Safety Automatic Devices", the protection setting value is one of the indispensable inspection items when testing relay protection devices. At present, the on-site commissioning work of the protection fixed value not only relies on...
