Transformer station process layer network collocation method based on virtual local area network technology

Technical field

The present invention relates to transformer station's technical field, particularly a kind of transformer station process layer network collocation method based on virtual local area network technology.

Background technology

Intelligent substation is the important step of intelligent grid; it is standardized as essential characteristic with full station information digitalization, communications platform networking, information sharing; automatically finish the basic functions such as information gathering, measurement, control, protection, metering and monitoring, and can support as required the senior functions such as electrical network is controlled in real time automatically, intelligence adjusting, on-line analysis decision-making, collaborative interaction.Along with the iterative method that intelligent substation is built, the design specification of various different electric pressure intelligent substations is also put into effect successively, for important directive function has been played in construction and the popularization of intelligent substation.Explicitly point out in the standard, the transformer station process layer network is as the tie of bay device and process layer devices in the contact station, mainly finish between wall and process layer devices, the bay device and the data communication between the process layer devices, can transmit sampled value (sampled value, SV) message and OO transformer station general purpose event (generic object oriented substation event, GOOSE) message.At present; along with the continuous maturation of technology and for improve protection reliability and simplified intelligent transformer station entirely stand design, reduce many-sided considerations such as number of devices, minimizing construction cost; in increasing intelligent substation, taked protection " directly to adopt straight jumping "; simultaneously process layer SV net and GOOSE net are united two into one the mode of SV and the transmission of GOOSE multicast message common network.Measure and control device, required SV, the GOOSE multicast message of monitoring function assembly (Network records analyzer, fault wave recording device etc.) of the information such as the connection locking on the process-level network between the main transmission protective relaying device, malfunctioning startup and wall.

Consider that SV multi-cast message data amount is large, take network bandwidth resources mainly with reaching the characteristics that GOOSE multi-cast message data amount is little, requirement of real-time is high, in the transformer station process layer network, need to data stream classify the guiding and flow control, to satisfy intelligent substation to the requirement of information real-time and high efficiency.Support VLAN (the virtual local area network of IEEE 802.1Q, VLAN) technology can realize the accurate control of intelligent substation network message, make each port of whole station internal procedure layer network switch only send necessary multicast message, the terminal equipment that links to each other with switch ports themselves simultaneously also receives only its required multicast message, efficiently solve the network conflict aggravation that the shared multicast transmission mode of tradition causes, intelligent terminal multicast mistake is received the increase problem, is widely applied in transformer station process layer networking plan.But for the Network records analyzer and fault wave recording device of Adoption Network sampling, it needs all SV and the GOOSE multicast message that transmit on the receiving course layer network.When intelligent substation is larger, the data traffic of transmitting on the internal procedure layer network that will cause standing is increased sharply, sometimes even can approach or exceed the 100 m ethernet light mouth capacity of the network switch, Network records analyzer and fault wave recording device, so that the wave carrier conflict of Internet Transmission, delay jitter aggravation, even the packet loss phenomenon appears, had a strong impact on the fail safe and stability of electric substation automation system.At present, existing scholar has launched correlative study for this problem.The Patents and the scientific and technical literature that retrieve have:

(1) Wang Wenlong, Liu Minghui. SMV net and GOOSE net common network possibility are inquired in the intelligent substation. Proceedings of the CSEE, 2011,31 (supplementary issue): 55-59.

(2) Xu Ke, Song Guowang, healthy and free from worry, Zhang Huijian, Yang Gang, huge rock. divide the GOOSE network collocating method of VLAN based on electric pressure. Chinese invention patent. application (patent) number: 200910069844.0. open (bulletin) day: 2010.04.07.

Document (1) mainly reduces load factor on the network switch by the 100 m ethernet switch being replaced by gigabit ethernet switch, improve real-time and reliability, but this will cause the significantly rising of cost of investment.In addition, when adopting this kind scheme, with the corresponding light interface of a large amount of intelligent terminals of network switch interface must upgrading be gigabit light mouth also, this also will cause the significantly increase of cost of investment.

Patent (2) is by vlan technology, proposes to divide the GOOSE network by electric pressure, simplified the VLAN configuration, Effective Raise operating efficiency.But this kind scheme is only applicable to the GOOSE network configuration, and is also inapplicable for the mode of SV and the transmission of GOOSE common network.

In addition, also having a kind of way is that the larger SV message information of data traffic in the station is delivered to Network records analyzer or fault wave recording device in direct-connected mode.A large amount of consumption of interior direct-connected number of fibers and Optical Receivers but this kind mode will cause standing when increasing cost, make in the station system architecture complicated, forfeiture intelligent substation information sharing advantage.

In sum, in the engineering practice, in the urgent need to a kind of new, effective process-level network allocation plan, when not reducing network transmission performance, do not increase cost of investment and not losing the shared advantage of station internal information, effectively solve when intelligent substation Internet Transmission flow larger, particularly the Internet Transmission flow approaches or the data reliable reception problem when exceeding the 100 m ethernet light mouth capacity of Network records analyzer and fault wave recording device.
