Abstract
The utility model discloses an IEC61850 communication-oriented network wave recorder, which comprises a network monitoring unit, a wave recording processing unit, a data storage unit, an SCD analyzing unit and a wave recording and message analyzing unit, wherein a message monitored by the network monitoring unit is buffered by the wave recording processing unit and then is sent to the data storage unit to be stored. The wave recording and message analyzing unit is communicated with the wave recording processing unit through a network interface, wave recording data is obtained from the data storage unit under the control of the wave recording processing unit, and the wave recording data is reduced into a waveform and combined with the analysis result of the SCD analyzing unit for analyzing the meanings of an original message in detail. The utility model not only solves the storage problem of large-flow messages on a network and also ensures the safety of the data; and in addition, an SCD document analyzing function conceals a complicated object-oriented variable description mode in an IEC61850 communication message and is replaced with engineering-oriented description with clear meanings, so that the analysis result is more intuitive.
Description
Technical field
The utility model relates to a kind of network record and involves record wave analysis device, relates in particular to a kind of network oscillograph towards IEC61850 communication.
Background technology
The IEC61850 communication standard has led the trend of transformer station of new generation development with characteristics such as its interoperability, flexible configuration, reliability height, high safeties.Being extensive use of of IEC61850 communication standard changes into process layer digitalization and transformer station's information transmission network and is possible, and in this simultaneously, the IEC61850 communication standard has also proposed new requirement to system debug, maintenance and accident analysis.In the digital transformer substation, process layer electricity look at hard connection and replaced by network communication mode, traditional oscillograph and malfunction elimination means can't play a role, therefore, how under the environment of network service, to reappear the communications status of each device in the station, fault generation front and back, the day-to-day operation situation of automated system, so that auxiliary system test and attendant be location and solution fault in time, become a hot issue of present electric substation automation system.
At present, have digitlization oscillograph, the Network records analytical equipment that is used for accident analysis on the market, the digitlization oscillograph of the band message analysis function of two functional unifications is also arranged.Existing record ripple record and analytical technology are for digital transformer substation and adopt the transformer station of IEC61850 standard traffic that favourable system debug and accident analysis means are provided.The network message that prior art adopts hard-disc storage to monitor, hard-disk capacity is little, and storage capacity does not reach the bottleneck that requirement has become prior art, and does not have SCD model analytical capabilities in existing digital oscillograph writing function and the Network records analytical equipment yet.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of network oscillograph towards IEC61850 communication is provided, and is applicable to that digital transformer substation also is applicable to the traditional transformer station that adopts the IEC61850 communication standard.
The technical solution of the utility model is: the utility model proposes a kind of network oscillograph towards IEC61850 communication, it is characterized in that: described network oscillograph comprises:
One is used for monitoring, writes down network message network monitoring unit 10;
A record ripple processing unit 20 that the message that collects is carried out buffer memory and processing;
A data storage cell 30 of storing recorder data and original message;
One be used for reading SCD file in the transformer station therefrom obtain each device in the transformer station the SCD resolution unit 40 of the engineering-oriented description of each information point of the literary composition of transmitting messages;
A record involves message analysis unit 50;
The output of described network monitoring unit 10 links to each other with the input of described record ripple processing unit 20, described record ripple processing unit 20 also links to each other with described data storage cell 30, the input that described record involves message analysis unit 50 is connected with record ripple processing unit by network interface, and the input of described SCD resolution unit 40 is connected to the input that described record involves message analysis unit 50.
The utility model contrast prior art has the following fruit of beneficial effect again: adopt disk array technology to solve the storage problem of big flow message on the network, guaranteed safety of data; SCD document analysis function has been hidden the OO variable description mode of the complexity of stipulating in the IEC61850 communication standard, replaces the engineering-oriented description that the meaning is understood, makes analysis result more directly perceived.
Description of drawings
Fig. 1 is the network oscillograph hierarchical structure schematic diagram towards IEC61850 communication;
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, involving 50 5 parts in message analysis unit towards the network oscillograph of IEC61850 communication by network monitoring unit 10, record ripple processing unit 20, data storage cell 30, SCD resolution unit 40, record forms.Wherein, network monitoring unit 10 receives message from a plurality of networks simultaneously by a plurality of network interface cards, and message is sent to data storage cell 30 and preserves after record ripple processing unit 20 caching process.Record involves message analysis unit 50, communicates by letter with record ripple processing unit by Ethernet, obtains data from data storage cell, in conjunction with the analysis result of SCD resolution unit 40, the storage data is recorded wave analysis.
The utility model is different from the innovation part that existing network record involves the message accounting analytical technology and is:
What 1, data storage cell 30 adopted is disk array.Disk array memory capacity is big, and is easy to operate, well solved the storage problem of big flow message, also guaranteed safety of data and record wave analysis result's reliability simultaneously.
2, record involves message analysis introducing SCD analytical capabilities.The information point descriptor that transmits in the IEC61850 message is the path of this information point in model file, and the commissioning staff often is difficult to understand rapidly corresponding which variable in these paths, has brought difficulty for engineering debug and accident analysis.The SCD analytical capabilities obtains the description of variable from model file, engineering-oriented description is translated in the path, makes the message analysis result more directly perceived, has more assistant adjustment and directive significance.
