Abstract

The invention relates to the automation of a digital relay protection tester, in particular to an automatic testing method for a relay protection device based on an IEC61850 standard. The automatic testing method comprises the steps that a tester client imports an SCD (Substation Configuration Description) file, testing parameters are automatically configured according to the relevant configuration information of the SCD file and a protection model corresponding to the tested relay protection device is selected; consistency check is performed to check the communication consistency of the protection device and the consistency of the configuration of the tester, so as to check whether equipment wiring, communication configuration and the like are correct or not. The automatic testing method for the relay protection device based on the IEC61850 standard has the advantages that the automation of the digital relay protection tester is realized, the universality of the tester is greatly improved by introducing the protection model and the testing quality is improved; the automation speed is greatly improved through the quick communication between the tester client and the protection device.

Description

technical field [0001] The invention relates to an automatic digital relay protection tester, in particular to an automatic test method for a relay protection device based on the IEC 61850 standard. Background technique [0002] With the gradual promotion and application of digital and intelligent substations, the IEC 61850 standard is widely used in substation automation systems. IEC 61850 enables the internal data of the relay protection device to have strong self-describing characteristics. The information model is established according to a unified method and data class. The operation brings the foundation and provides an opportunity for the automation of the digital relay protection tester. [0003] The automation of the relay protection tester is inseparable from the communication function of the station control layer, but there are still many problems in the MMS communication function of the station control layer in actual engineering applications. At present, severa...
