摘要:
Embodiments of the present invention disclose a packet synchronization method and system of an intelligent substation process layer network, wherein the method includes: recording transmission delay on a network transmission device in a sampled value (SV) packet sent by a merging unit; and implementing, by a SV data receiving device, packet synchronization according to the transmission delay on the network transmission device recorded in the SV packet, so as to achieve that the SV data receiving device synchronizes received packets of different merging units, and accordingly ensure that the SV data receiving device can correctly perform data calculation and actions. Such a method can solve the problem that the current process layer network relies too much on a time synchronization network.
摘要:
The present invention provides a control system based on a crossed multi-ring-network redundant network topology structure. The control system includes: a control object having a plurality of groups of first connection nodes; and a plurality of controlled objects, each of the plurality of controlled objects having one or a plurality of groups of second connection nodes, wherein any one of the plurality of groups of first connection nodes in the control object are sequentially connected to the second connection nodes of at least two of the plurality of controlled objects to form a ring network, the plurality of groups of first connection nodes corresponding to the control object form a plurality of ring networks, and the plurality of ring networks include the plurality of controlled objects. According to the control system in the present invention, the connection nodes of the control object can be connected to the plurality of controlled objects to form the ring networks, such that the number of the connection nodes of the control object can be effectively reduced, thereby reducing the power consumption of the control object. Moreover, since there are redundant connections between the control object and the controlled objects in the control system, the reliability of the whole control system is improved.
