Accompanying drawing explanation
Fig. 1 is this utility model electric power time synchronized monitoring platform building plan.
Fig. 2 is this utility model provincial Power time synchronization system topological diagram.
Detailed description of the invention
As shown in Figure 1, a kind of electric power time synchronized monitoring platform based on OTN and PTN transmission network, it is the monitoring platform that devices at full hardware is built, including plant stand end time synchronism apparatus, described plant stand end time synchronism apparatus is connected with the OTN equipment supporting PTP protocol in electric power wide area and PTN device, and the clock server of described also each with the whole network node of plant stand end time synchronism apparatus is connected.
OTN equipment and the PTN device of supporting PTP protocol in above-mentioned electric power wide area refer to:ContainThe OTN equipment of PTP setting network interface board and PTN device.
Above-mentioned plant stand end time synchronism apparatus is also associated with protection device.
Above-mentioned time synchronized monitor supervision platform is built based on OTN and PTN transmission network, and electric power wide area is by core layer, convergence-level and access network triple layer designs, and wherein core layer uses OTN transmission equipment, convergence-level and Access Layer to use PTN transmission equipment.OTN and PTN transmission equipment independently carries PTP protocol, and wherein the PTP protocol of IEEE 1588 standard supported by PTN transmission equipment itself, directly for plant stand end equipment issue precision reach submicrosecond level pair time signal.For realize the equipment submicrosecond levels such as power system traveling wave fault location, wide area phasor measurement, electronic mutual inductor merging unit pair time precision, this utility model be network each node OTN transmission equipment configure PTP interface board.
As in figure 2 it is shown, the network topology of power clock synchronization monitoring platform is as the time centre of the whole province at the centrally disposed a set of PTP master clock of provincial regulation and control, provide time base source for provincial OTN transmission network.Complement one another as standby time center, the clock adjusted with province saving standby regulation and control center configuration a set of PTP master clock.The PTN network configuration clock synchronization compliant with precision time protocol of company of prefectures and cities, both as company of province and standby regulation and control center main clock from clock, the master clock as regional administrative transformer station uses again.Each plant stand time synchronism apparatus configuration clock synchronization compliant with precision time protocol, obtains time synchronizing signal, both using from clock as prefecture-level company's master clock by PTN transmission network, and the master clock as observing and controlling in transformer station and protection device uses again.According to such scheme, between provincial scheduling, back scheduling center, prefecture-level company, plant stand, set up well-bedded time synchronization network by provincial OTN transmission network and prefecture-level PTN transmission network.
During enforcement, above-mentioned electric power time synchronized monitoring platform hardware is built according to above topology structure, as it is shown in figure 1, the management information of plant stand end and company of prefectures and cities can upload to province's dispatching control center by power dispatch data network.
The utility model has the advantage of: build the hardware platform of a time synchronized, thus set up the whole network time synchronized.Utilize the PTN transmission equipment supporting PTP protocol, too much investment need not be put in electric power wide area.For plant stand end, time synchronized server can be integrated in monitoring system background server；Laying of cable can be reduced simultaneously; as a example by certain the 220kV intelligent substation built; if 1 main transformer and the outlet scale of 4 times 220kV; light B code Dui Shi 96 tunnel needed; electricity B code Dui Shi 32 tunnel; optical cable and cable need reserved standby core, use this utility model to reduce time synchronized screen cabinet cable about 1km and optical cable 3km to each protection/observing and controlling screen cabinet, on the spot convergence control cabinet.
