Intelligent substation is the important step of intelligent grid; it is standardized as essential characteristic with the information digitalization of entirely standing, communications platform networking, information sharing; automatically complete the basic functions such as information gathering, measurement, control, protection, metering and monitoring, and can support as required the senior functions such as the real-time control automatically of electrical network, intelligence adjusting, on-line analysis decision-making, collaborative interaction.Than traditional transformer station, the network communications technology has become the key technology of intelligent substation.Information exchange in standing between secondary device all realizes in the mode of data message, as exchange event and state data between cell device and monitoring system of electric substation realize with the MMS message transmissions; The exchange of process layer and wall is controlled and status data, between bay device, the process layer devices swapping data realizes with the GOOSE message transmissions; Process layer and wall exchange sampled data realize with the SV message transmissions.How the data message is carried out to real time monitoring and analysis, find in time the mistake in communication process, and carry out alarm and become in the intelligent substation construction problem of paying close attention to and solving of needing badly.Under this background, the network message recorder analyser arises at the historic moment.
At present, the network message recorder analyser has obtained application in intelligent substation, it is by MMS, GOOSE and SV message in the Real-time Collection intelligent substation, can monitor in real time that the operation conditions of each secondary device in intelligent substation is also in time to extremely being reported to the police, and can carry out off-line analysis to the recorded data message, thereby search the interior hidden danger existed of intelligent substation and abnormal and error reason abnormal, that the analysis intelligent substation is interior, instruct the relevant personnel to locate and get rid of hidden danger and fault.For giving full play to the information sharing advantage of intelligent substation, the data acquisition of network message recorder analyser realizes by network usually, each arranged spaced one interstation of secondary device is every switch, and the merge cells at this interval (sending SV message and device alarm GOOSE message containing electric current, information of voltage), intelligent terminal (sending and receiving GOOSE message), protective device (send the GOOSE message and receive GOOSE and the SV message) and measure and control device (send the GOOSE message and receive GOOSE and the SV message) all are connected on this switch; Information interaction between merge cells, intelligent terminal, protective device and measure and control device has forwarded by the interval switch.Collection for the MMS message, the network message recorder analyser is the Port Mirroring function of utilizing the MMS network switch, by supervisory control system, senior application server and telemechanical and MMS Port Mirroring that the network switch connects to the MMS network switch and network message recorder analyser connected port, thereby realize the MMS message of supervisory control system, senior application server and telemechanical is gathered.
Network communications technology, when giving full play to the shared advantage of intelligent substation internal information, is also brought many problems of considering and noting that need, as the loading problem of communication network.It has been generally acknowledged that, when offered load surpasses 40%, will cause network performance significantly to reduce, be prone to the unsettled situations such as packet loss.Therefore, when the planning network structure is connected with the interior secondary device networking of being stood, should note making the load of each port to be no more than 40% of its port speed.In intelligent substation, the network switch used generally adopts 100,000,000 ports (100Mbit/s) at present, and therefore, the flow of each port of the network switch should be no more than 40Mbit/s.
Than the SV message, the flow that the GOOSE message produces almost can be ignored, and the flow that the MMS message produces is also far below the SV message, so offered load is mainly produced by the SV message.Usually, the load flow that network message recorder analyser MMS message gathers port can meet the requirement that is less than 40Mbit/s, should mainly consider loading condition that the SV message produces and the network message recorder analyser disposal ability to the SV message.
Intelligent terminal receives only and sends the GOOSE message, and its message gathers port flow and certainly is less than the 40Mbit/s limit value; Protective device in interval, measure and control device mainly receive SV message and the GOOSE message in interval, because the GOOSE message flow can be ignored, a SV message based on the IEC61850-9-2 stipulations is about 7Mbit/s, therefore, protective device, measure and control device message gather port flow and are about 7Mbit/S, are less than the limit value of 40Mbit/s; The network message recorder analyser need to gather the spaced SV of institute and GOOSE message, same, because the GOOSE message flow can be ignored, therefore it gathers port flow, is mainly the SV message flow, is about (7*N) Mbit/s, and N is space-number.As can be seen here, when N is greater than 6, the collection port flow of network message recorder analyser will, over the limit value of 40Mbit/s, must take measures to meet its functional requirement.The most directly mode is to be gigabit networking by network upgrade, but this will significantly increase the construction cost of intelligent substation undoubtedly.In addition, consider that all kinds of protections of current intelligent substation, observing and controlling and switch device still generally adopt 100-M network Ethernet, data processing speed also is restricted, and is difficult to process hundreds of million data.
Therefore, when in the intelligent substation station, interval is more, in the urgent need to a kind of new network message record analysis instrument system, when not increasing the intelligent substation construction cost, effectively solve network message recorder analyser message and gather message Quick Acquisition and the reliable reception problem of port message flow when excessive.
