The invention discloses a regional power network intelligent equipment time analyzer which comprises an analysis main control module, an Ethernet module with an IEEE1588 time synchronization function, an electric Ethernet module, an IRIG-B and pulse clock optical-electric BNC signal form input and output module, a satellite signal receiving module and a portable clock module. The Ethernet module, the electric Ethernet module, the input and output module, the satellite signal receiving module and the portable clock module are connected with the analysis main control module. The regional power network intelligent equipment time analyzer is supportive of time synchronization accuracy index analysis evaluation and IEEE1588 uniformity testing, can provide an intelligent device time synchronization index tester which is convenient to use, effectively overcomes a series of problems of insufficiency in intelligent equipment time accuracy index and IEEE1588 product testing means, incapability of effectively performing abnormity testing, narrow test coverage, difficulty in error positioning during testing and the like of current regional power networks and intelligent transformer substations, is suitable for intelligent equipment, related to the regional power networks and the intelligent transformer substations, such as combiners, intelligent terminals, IEEE1588-supportive exchangers, clock source equipment and protection control equipment, and has important practical value.
