Abstract

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.

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...
