Abstract

The invention discloses a relay protection automatic testing method. The relay protection automatic testing method mainly includes the steps of receiving a testing request and editing a testing template and a reporting template of a relay protection device; generating voltage and current values according to operation constant values of the relay protection device and the testing template; controlling a replay protection tester to output voltage and current analog quantity data to the relay protection device according to the voltage and current values; obtaining protective action information and / or protective action message information generated by the relay protection device according to the voltage and current analog quantity data; conducting testing according to the protective action information and / or the protective action message information, and generating testing results. Testing is carried out in cooperation with protection constant values generated by the relay protection device, testing of the protection device can be reliably, efficiently and automatically completed, a testing report is generated according to the testing results, and the actual requirement for work efficiency improving of field debugging is met.

Description

technical field [0001] The invention relates to an automatic testing method, in particular to an automatic testing method for relay protection. [0002] Background technique [0003] The safe and stable operation of the power grid is the premise and basis for realizing the reliability of power supply. As the first line of defense of the power system, relay protection is one of the essential devices to ensure the safe and stable operation of the power grid and equipment. In various power plants, substations and user power supply systems, a large number of relay protection devices are used to realize various protection functions. According to the "Inspection Regulations for Relay Protection and Power Grid Safety Automatic Devices", the protection setting value is one of the indispensable inspection items when testing relay protection devices. At present, the on-site commissioning work of the protection fixed value not only relies on the commissioning personne...
