Description

technical field [0001] The invention relates to an automatic test system, in particular to an automatic test system 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 personnel to m...
