Background technology
Merge cells is the bridge of sampled data between instrument transformer and wall intelligent electronic device; it compiles the data channel of a plurality of electronic mutual inductors; also can compile and the sample analog signal of traditional instrument transformer output or the simulation small-signal of electronic mutual inductor output, and secondary devices such as electric testing instrument and protective relaying device are provided the electric current and the voltage sample of one or more groups time correlation.The mode of merge cells output has two kinds, the serial communication mode that the first defines in IEC60044-7/8 based on Manchester's code, and it two is the ethernet communication modes based on IEEE802.3 that define in IEC61850-9.Because the former transmission rate is slow, has limited sample rate, simultaneously because IEC61850 has become the international standard of word electric substation automation system, so modal mode is exported based on the network interface of IEC61850-9-2 in the present engineering construction.
In digital transformer substation, merge cells may link to each other with the intelligent electronic device of a plurality of walls by a plurality of network interfaces.The requirement that is connected to the SV message that the intelligent electronic device of the different interval layer on the same merge cells send on the unit because of the function difference is combined is also inequality; the wall intelligent electronic device that is used for protecting and is used to measure requires the sample frequency gap of analog quantity of the SV message that send bigger; they are also inequality to the data set content in the SV message, and this merge cells of will seeking common ground can be different from the SV message possibility that different network interfaces are sent.
In existing engineering is used, the SV message that same merge cells is sent from different network interfaces is the same, therefore can not carry out separate configurations to the SV message of each network interface, the characteristic parameter from sample frequency, data set content and the message of the SV message of different network interfaces outputs all can not independently be provided with.
The utility model content
The utility model is at the prior art above shortcomings, a kind of merge cells with two net independent sample functions is provided, can export two groups of fully independently SV messages from different network interfaces, therefore the different network interfaces of same merge cells can be formed the process layer SV net of two complete independent samples, the sample frequency of these two online SV messages can independently be provided with, the data set content of SV message can independently be provided with, characteristic parameter (the MAC Address of SV message, APPID and SVID) can independently be provided with, the cell device of difference in functionality all can obtain the SV message that satisfies self needs from the same merge cells like this.
The utility model is achieved through the following technical solutions, the utility model comprises: the message configurator, two interpolation are sampler again, two communication processors and data input processor, wherein: the input of data input processor links to each other with communication port, first interpolation again sampler and second interpolation again the input of sampler all link to each other with the output of message configurator and the output of data input processor, first interpolation output of sampler again links to each other with the input of first communication processor, second interpolation output of sampler again links to each other with the input of second communication processor, and the output of the output of first communication processor and second communication processor links to each other with process layer SV network respectively.
The advantage of this device is: there is two interpolation sampler again the merge cells inside that the utility model is described, sampler is independent fully again for these two interpolation, each interpolation sampler again can be according to the message configuration information that is received, the crude sampling value of each passage of input is made interpolation again after the sampling processing, form separately independently SV message, give two different process layer SV networks by different communication interface moduless.The sample frequency of these two online SV messages can independently be provided with, the data set content of SV message can independently be provided with, the characteristic parameter of SV message (MAC Address, APPID and SVID) can independently be provided with, the cell device of difference in functionality all can obtain the SV message that satisfies self needs from the same merge cells like this, this had both satisfied the technical specification of national grid digital transformer substation, had reduced the process bed device of analog acquisition again.
