Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 A method for implementing a protective device test by using recording and playback includes the following steps:

[0024] (1) Construction of typical fault waveform question bank

[0025] First organize relay protection experts to classify and sort out the typical power grid faults faced by various types of protection, and form a typical power grid fault outline classified by voltage level and protection type; then use RTDS real-time digital simulator to simulate according to the typical power grid fault outline Corresponding faults are recorded into COMTRADE99 format waveform files; finally, for each fault waveform, the action corresponding to the protection is pre-configured, and the record of this action is stored in the question bank in the form of IEC61850 model.

[0026] (2) Test process

[0027] 1) Select the a...

Abstract

The invention relates to the technical field of transformer substation protection devices, and specifically relates to a method for realizing device test protection through recording and playback. The method comprises the following steps: (1) the typical failure waveform question bank establishment process: 1) protection is classified according to logical functions specified by IEC61850; 2) and a corresponding typical failure waveform is recorded for each type of protection through an IED detect detector, and a test question bank is generated for an anticipated action of the corresponding failure waveform is inputted manually; (2) and the test process: 1) an appropriate test question bank is selected according to the logical function classification of the tested protection; 2) the protection is connected to the IED detect detector, and a synchronous clock is connected; 3) the test question bank is played back by the IED detect detector, and the action output of the tested protection is received by the IED detect detector; 4) and the action of the tested protection is compared with the anticipated action in the test question bank to judge the test result. The method of the invention has advantages of low cost and convenience, the protection device has advantages of small size and easy carry, so the protection device is suitable for the field tests of various transformer substations, so that advantages of easy utilization and easy operation can be realized.

Description

technical field [0001] The invention relates to the technical field of substation protection devices, in particular to a method for realizing protection equipment tests by recording and playing back. Background technique [0002] At present, the operating state of the substation is monitored and detected through a dynamic model test, which is realized through a recording and playback protection device. The dynamic simulation test is a dynamic simulation test, which simulates various operating conditions and fault states of the actual substation on the RTDS, and conducts a real-time assessment of the function and performance of the protection and control devices operating in the power system to ensure protection and control. The test of the reliable operation of the device in the field. [0003] However, the existing RTDS recording and playback protection equipment has the following problems: there is no fixed test fault database, and comparison is difficult; the equipment i...
