Abstract

The invention provides a relay protection AC sampling test system, which comprises a relay protection tester, a relay protection device and a test system. The relay protection tester is connected with the test system. The relay protection tester is connected with the relay protection device through a signal line. The relay protection device is connected with the test system. The test system comprises a test interface layer module used for generating voltage and current values according to a user test request, a hardware interface used for being connected with the relay protection tester, controlling the relay protection tester to generate voltage and current analog quantity data according to the voltage and current values, and outputting the voltage and current analog quantity data to the relay protection device, and a test layer module used for obtaining a sampling value generated by the relay protection device, and carrying out a test in combination with the voltage and current analog quantity data. By means of the relay protection AC sampling test system, protection equipment can be tested reliably, efficiently and automatically, thereby improving test efficiency.

Description

technical field [0001] The present invention relates to a testing technology of a relay protection device, in particular to a relay protection AC sampling test system. Background technique [0002] 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 AC sampling value is one of the indispensable inspection items when testing relay protection devices. At present, the on-site commissioning of AC sampling values ​​not only relies on the commissioning personnel to manually compl...
