Problems solved by technology

[0003] The detection system in the prior art generally can only be aimed at one wiring mode, and the detection object is single, and in the process of the anti-mislocking logic test process, the negative test cannot be carried out due to the association between the equipment state and the current test equipment state; and the detection results Most of them are realized by manual comparison, and there are large errors

Embodiment 1

[0051] A detection method for a one-button sequential control system of an intelligent substation, such as figure 1 As shown, the method includes:

[0052] Step 1: Communicate the one-button sequential control detection system with the system under test through the switch to obtain the information of the system under test;

[0053] Step 2: Based on the information of the one-button sequential control detection system and the system under test, data distribution is carried out according to the preset SCD model;

[0054] Step 3: The system under test performs device state migration based on the device state migration method specified by the one-key sequential control detection system;

[0055] Step 4: The one-button sequential control detection system issues remote control instructions to the migrated system under test, performs affirmative and negative tests of the one-key sequential control anti-mislocking logic of the device under test, and compares the test results with Expe...

Embodiment 2

[0067] Based on the same inventive concept, the present invention also provides a detection system for a one-button sequential control system of an intelligent substation, such as figure 2 Shown:

[0068] The switch connects the one-button sequence control detection system, the sequence control host, the intelligent anti-error host and the measurement and control device to form a network for unified data distribution; the tester provides switching and analog signals for the measurement and control device; the measurement and control device will test the switch Quantitative and analog signals are converted into unified data conforming to the DL / T 860 protocol format, providing basic data for the one-button sequence control detection system and sequence control host

[0069] The detection system includes the main wiring diagram of the test system, the SCD model, the definition of the migration equipment state, a one-key sequence control detection system server, a switch, an OMI...

Abstract

The invention discloses a detection method and system for a one-key sequential control system of an intelligent substation, and the method comprises the steps: a one-key sequential control detection system communicating with a detected system through a switcher, and obtaining the information of the detected system; performing data distribution according to a preset SCD model based on the information of the one-key sequential control detection system and the detected system; the detected system performing equipment state migration based on an equipment state migration method specified by the one-key sequential control detection system; the one-key sequential control detection system issuing a remote control instruction to the migrated detected system, performing positive and negative testson the one-key sequential control anti-misoperation locking logic of the tested equipment, and automatically comparing a test result with an expected result to obtain a comprehensive anti-misoperationlocking logic test result; wherein the SCD model is designed on the basis of a main wiring diagram containing various wiring modes of a one-key sequential control detection system. According to the technical scheme provided by the invention, logic decoupling of the equipment state and the current test equipment is realized through equipment state migration, the test configuration is simplified, and the correctness and the coverage rate of an anti-error logic test are improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection method and system for a one-button sequential control system of an intelligent substation. Background technique [0002] One-button sequential control is an operation mode for substation switching operation, which can realize software prefabrication of operation items, modular construction of operation tasks, automatic identification of equipment status, intelligent verification of anti-error interlocking, one-key start of operation steps, and automatic operation process Execute sequentially. Call the corresponding sequential control ticket on the station monitoring background machine or dispatching monitoring computer to change the substation equipment from one state to another, saving a lot of manpower and material resources, and at the same time, there is no need to directly perform manual operations on the primary equipment The operation also improves the safety accordingly,...
