System and method for automatically testing relay protection devices of intelligent transformer substations on basis of cloud storage

Abstract

The invention discloses a system and a method for automatically testing relay protection devices of intelligent transformer substations. The system comprises a cloud server, a two-dimensional code recognition device and a control and processing device. Two-dimensional code labels are arranged on the to-be-tested relay protection devices; the cloud server comprises data storage modules, and parameter data and two-dimensional codes of the relay protection devices are stored in the data storage modules; the two-dimensional codes on the to-be-tested relay protection devices can be acquired and recognized by the two-dimensional code recognition device, and the control and processing device comprises control and processing modules and data acquisition modules. The method includes acquiring the parameter data of the to-be-tested relay protection devices from the data storage modules of the cloud server according to two-dimensional code recognition result data by the control and processing modules; then generating corresponding test item list data and testing items one by one; acquiring test procedure parameter data by the data acquisition modules, generating test reports according to thetest procedure parameter data by the control and processing modules and outputting the test reports. The parameter data, which are about to be acquired from the data storage modules of the cloud server, of the to-be-tested relay protection devices correspond to the two-dimensional codes. The system and the method have the advantages that the relay protection device test efficiency can be improvedby the aid of the system and the method, and the test accuracy can be improved.

Description

technical field [0001] The present invention designs the technical field of monitoring relay protection devices of intelligent substations, in particular to an automatic testing system and method for relay protection devices of intelligent substations using cloud storage and MMS protocol. Background technique [0002] As an important part of a strong smart grid, smart substations have been vigorously promoted and constructed in China, and intelligent secondary equipment such as intelligent relay protection devices have also been more and more widely used. At present, the smart substation adopts the IEC61850 standard, which strictly limits the functions, values, interfaces and other aspects of the protection device, realizes the standardization, standardization and unification of the design, and also provides convenience in the interactive sharing of data. [0003] But at present, the test link of substation relay protection device still stays in the traditional way. Through...

Problems solved by technology

At the same time, the existing protection device test system is usually carried out for a single device. Although the test interface of the device has been standardized, it is still necessary to repeatedly perform communication configuration and modification of test items and parameters during the test process, which requires a lot of investment. Manpower and material resources can only be completed, automation cannot be realized, and the advantages of high informatization of smart substations have not been reflected

[0004] At the same time, due to the limitation of manual operation speed and proficiency, the test of the protection device takes a lot of time to complete, which also objectively causes problems such as generally long test cycle and decreased test accuracy, which cannot adapt to the high-efficiency, Requirements for reliable operation and daily operation and maintenance
