Abstract

The invention provides an implementation system and method for delay information during intelligent substation process level network switching. Delay of relay protection network data traffic inside network nodes is informed through the time stamp position and hardware timestamp determining technology, and therefore network transmission delay is determined. According to the implementation system and method, the delay inside the network nodes is measured, and the method is high in operating rate, high in precision, easy to implement and capable of accurately and rapidly measuring the delay of the network nodes, so that the problem that the delay of the relay protection service network data is not known is solved, supports are provided for relay protection network sampling and tripping, and the implementation system and method have practical engineering application value.

Description

Technical field [0001] The invention belongs to the technical field of power system operation and planning, and specifically relates to a system and method for implementing switching delay notification of a process layer network of an intelligent substation. Background technique [0002] At present, the relay protection in the substation adopts the direct jump method, that is, the protection device and the merging unit adopt a point-to-point method. This method is more reliable, but the wiring is more complicated, a lot of cables or optical cables are wasted, and information cannot be shared. Smart substations require digitization of information throughout the station, networking of communication platforms, and sharing of information platforms. Ethernet technology is a relatively mature and feasible technology in the field of industrial control. The existing smart substation adopts a two-layer network communication architecture, namely, the process layer network and the bay laye...
