Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an automatic detection system and a detection method for information transmission time of an intelligent relay protection device. Background technique [0002] Intelligent relay protection device is an important part to ensure the reliable operation of smart grid. When a fault occurs in the power grid, in order to analyze the fault and restore power supply as soon as possible, the relay protection device is required to send the protection action information and displacement information to the dispatching master station in time. [0003] The process of sending relay protection device information is: when the relay protection device generates protection action information or displacement information, it first sends it to the data communication gateway, and the data communication gateway receives the information and then sends it to the simulation master station. The existi...
