Description

technical field [0001] The invention belongs to the field of time synchronization testing of regional power grids of electric power systems and smart equipment of intelligent substations, and in particular relates to a time analyzer for smart equipment of regional power grids. Background technique [0002] In the regional power grid and smart substation process layer, the highest requirement for time synchronization accuracy is 1 microsecond. At this stage, the clock synchronization function of the real-time relay protection control of regional power grids and smart substations basically adopts the IRIG-B code method and the IEEE1588 method. [0003] The IEEE1588 protocol is a precision time protocol, which is very suitable for realizing the clock synchronization function of the regional power grid network protection control function. If the smart device adopts the hardware-assisted time stamping method, the time synchronization accuracy can reach sub-microseconds, which ful...
