Problems solved by technology

In this case, the relay protection device suppliers need to analyze the action behavior of the relay protection. The relay protection device with protection start can be analyzed through the recording wave triggered by the protection start, and the relay protection device without protection start Because the wave recording is not triggered, there is no way to analyze the wave recording data

Embodiment 1

[0073] This implementation provides a recording trigger method used in the relay protection device test based on binary input, such as figure 1 , including the following steps:

[0074] S1: Set the test binary input channel number, test binary input advance time and test binary input width in the relay protection device;

[0075] S2: Set the binary input setting time and binary input reset time, and initialize the binary input setting time and binary input reset time;

[0076] S3: set the sampling period;

[0077] S4: Detect the binary input, and update the binary input setting time and binary input reset time according to the binary input;

[0078] S5: Calculate the binary input time according to the updated binary input set time and binary input reset time;

[0079] S6: If the binary input time is less than or equal to the judgment threshold, the relay protection device triggers wave recording.

[0080] In step S1, the test binary input channel number nC, the test binary...

Abstract

The invention discloses a method and system for triggering a binary input relay protection device with wave recording. The method includes S1: setting the test binary input channel number, the test binary input advance time and the test binary input in the relay protection device Width; S2: Set binary input setting time and binary input reset time, and initialize binary input setting time and binary input reset time; S3: Set sampling period; S4: Detect binary input, according to binary input Update the binary input setting time and binary input reset time; S5: Calculate the binary input time according to the updated binary input setting time and binary input reset time; S6: If the binary input time is less than or equal to the judgment threshold , the relay protection device triggers the wave recording. The invention can also trigger the wave recording when there is no protection start, and it is convenient to analyze whether the action behavior of the device is correct under any test situation through the wave recording data.

Description

technical field [0001] The present invention relates to the technical field of relay protection, and more specifically, to a recording trigger method and system used in a binary input-based relay protection device test. Background technique [0002] For a power grid enterprise in a region, it generally manages a lot of substations, and a lot of suppliers' products are running in many substations. There are certain differences in the external characteristics of these products, and sometimes the differences are very large. These differences bring some inconvenience to the operation and maintenance of the substation. [0003] In order to reduce the inconvenient operation and maintenance problems caused by the differences in suppliers' products, power grid companies have made standardized design requirements for the products supplied to substations. Microcomputer relay protection device is one of the main products that power grid enterprises require standardized design. [00...
