Abstract

The invention provides a relay protection AC sampling test system, the system includes: a relay protection tester, a relay protection device and a test system; the relay protection tester is connected to the test system, the relay protection tester is connected to the relay through a signal line The electric protection device is connected to the test system of the relay protection device; wherein, the test system includes: a test interface layer module for generating voltage and current values ​​according to user test requests; a hardware interface for connecting the relay protection tester to control the The relay protection tester generates voltage and current analog data according to the voltage and current value, and outputs the voltage and current analog data to the relay protection device; the test layer module is used to obtain the sampled value generated by the relay protection device, and Combining the voltage and current analog data for testing. Through the invention, the test of the protection device can be completed reliably, efficiently and automatically, thereby improving the 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...
