Definitions

  • FIG. 1 shows a block diagram from these draft standards, which the basic connection of a converter 1 with a subordinate converter, for example an analog-digital converter 2 with assigned power supply, to a digital Show transmission link 3.
  • These draft standards see one exactly defined transmission time for a telegram with samples in front. It will be the time between scanning the analog output variable of the respective converter and the Receipt of the telegram with the sample values defined.
  • secondary Converter 4 and 5 are provided for adaptation.
  • the draft standards propose the digital measured variables of the converters for a branch in a substation, for example, using a so-called "merging unit", a data concentrator 10.
  • the data concentrator 10 outputs an output 11 a telegram with the digital measured variables to a not shown protection or field device and is over a Auxiliary input 12 with a clock, also not shown connected.
  • elements 1 and 2 are in accordance with 1 each with PC and the elements 4 and 5 with SC.
  • the digital measured variable formed by the converter to the data concentrator is from an equidistant Sampling of the individual analog output measurands the converter ran out. Furthermore, it is assumed that a time synchronization of the sampling of the Output parameters of the various current and voltage transformers also from different branches of the substation is required. There are two ways to synchronize the scan to:
  • the first way could be to use the interpolation method his.
  • the different, known Time delays between sampling in datagrams sent samples of the output measurands and the reception of the datagrams in the data concentrator and the measurable Delay between the receipt of the various datagrams the individual transducer is used to match each received sample assign a microsecond-precise sampling time. Then between the individual samples interpolated to all received samples on a common Convert the sampling time.
  • Fig. 3 illustrates this fact. This figure is the above. Taken from draft standard.
  • the disadvantage of this method is the high cost of the timestamp facility for the received datagrams and the required setup for interpolation of the sampled signals in real time.
  • an interpolation polynomial for interpolation e.g. 3rd order recursive spline interpolation
  • the interpolation becomes an additional interpolation error caused.
  • the result of the interpolation can no longer be used with a linear transfer function describe, i.e. the algorithm used is non-linear.
  • adaptive filters can also be used.
  • the relatively high group term affects the case practically realizable all-pass filter (or low-pass filter with a cutoff frequency significantly higher than that too using bandwidth).
  • the Tracking the adaptive filters in this case a device with which the filter coefficients to be updated are required can be calculated.
  • a device with which the filter coefficients to be updated are required can be calculated.
  • the LMS algorithm To this algorithm To realize, either a digital signal processor DSP or a complex ASIC required.
  • the second way is to use a substation-wide Synchronization pulse. Because in a substation the signals provided by the converters usually used by different devices, it is actually never possible to convert a substation into individual ones Disassemble sections in which a common Sampling clock for all output measurands to be synchronized the converter can be used. It always has to entire substation supplied with a central sampling clock In this case, all converters can be synchronized generate sampled values from one another.
  • Fig. 4 shows the image used in the draft standard already mentioned to illustrate the synchronously sampled signals.
  • the draft IEC 61850-9-1 uses a 100 Mbit Ethernet interface proposed.
  • Ethernet interfaces is basically a central sampling clock required for the synchronization of the scanning, because at this transmission method does not have a constant transmission time the converter signals are guaranteed via the Ethernet bus can. This is the one in this draft standard proposed method for digital transmission of Converter signals only around a different implementation variant of the 2. Procedure according to draft standard IEC 60044-8.
  • Both designs are based on the requirements of protection - and Control technology tailored. For transient recording and power Quality measurements are unsuitable for both designs (too low Sample rates).
  • the achievable according to IEC 60044-8 and 61850-9-1 Sampling rates are in the range of 1 ... 5 k samples / s.
  • the required for transient recording and power quality measurements Sampling rates are in the range 5 ... 40 k samples.
  • the invention has for its object the just described to further develop known methods so that it can be Trap allowed to get good results.
  • a method is used to achieve this object for recording and digital transmission of analog Output measurands of several converters to one protection or Field device in which the analog output measured variables each Converter with a sampling rate that is higher than a factor the minimum sampling rate is converted into digital measurands and their transmission is carried out, the factor an integer divisor of the number of filter coefficients one FIR filter each with filter coefficients of the value 1 is in a data concentrator for each converter that digital measurands as a telegram to a data concentrator are transmitted, being assigned from each transducer Buffering with a clock (clock) data in the FIR filters upstream secondary buffers are taken over, the clock from the synchronous character of the respective Telegram and the fixed clock of a clock generator formed and in the data concentrator by means of a multiplexer output buffers downstream of the FIR filters a transmission telegram with a reduced sampling rate digital measured variables of the converter and that Send telegram is transmitted to the protection or field device.
  • the analog output measured variables each Converter with a
  • the process is carried out with the digital measurement variables by means of a isochronous logic arrangement generates a telegram and from one transmitter each to one data receiver at data concentrator transfer.
  • the invention further relates to an arrangement for detection and digital transmission of analog output measurands several converters to a protection or field device and the task arises, which can be gathered from WO 01/45232 known arrangement to upgrade.
  • this object is achieved in one Arrangement for the acquisition and digital transmission of analog Output measurands of several converters to a protection or Field device in which each converter is one with a factor higher than the minimum sample rate selected by the working Analog-digital converter for the formation of digital Measurands is subordinate; where the factor is an integer Divisor of the number of filter coefficients one each FIR filters with filter coefficients of value 1 in a data concentrator is for every converter; the outputs of the analog-to-digital converters stand in with the data concentrator Connection, and at the data concentrator is everyone on the input side Converter assigned a buffer; to the Buffer memories are connected to the are connected on the output side to the FIR filters, and a Multiplexer is subordinate to the FIR filters Output buffer connected; the data concentrator has one connected to the protection or field device Output for sending a send telegram with in your Sampling rate reduced digital measured variables of the converter.

  • subsequent buffers Buf1 those completely received by the data receiver Rx Telegrams written with the clock of the data receiver Rx.
  • Each data receiver Rx is operated with its own clock. This clock is synchronous to the clock of the connected one Transmitter Tx and is made from the synchronous character of the transmitted telegram generated.
  • the data concentrator 26 also includes FIR filters FIR that buffers Buf2 are each subordinate, which in turn are connected to the buffer Buf1. On the output side, the FIR output buffers are located on the filters Buf 3. The output buffers Buf3 is on Multiplexer 27 downstream.
  • each of the analog-to-digital converter 21 generated digital measured quantities Md isochronous transmitted with the clock of the A / D conversion.
  • the A / D implementation and the transmission of the samples over the optical fibers LWL is done with a factor of m the sampling rate of the output signal A at the output module 28 of the multiplexer 27 higher sampling rate, the factor m an integer divisor of the number of filter coefficients n of the FIR filter FIR is that of reducing the sampling rate the transmitted digital measured variable Md by a factor of m serves. This is achieved by using FIR filters Filter coefficients with the value 1 can be used. It takes place So in the FIR filter a summation of m in each case Values.
  • the data concentrator 26 runs at its own clock Clock operated.
  • This bar is formed from the bar of one Clock generator, not shown, which is asynchronous to the clock the receiver is Rx but has the same frequency.
  • the synchronous signal of the telegram becomes the clock to the respective receiver Rx by using a single clock clock arises whenever the synchronous signal and at the same time an impulse of the not shown Clock generator occurs.
  • Buf2 will synchronize with the clock the data of the complete received telegrams (i.e. the samples of the individual converter) from the buffer store Buf1.
  • the secondary buffers Buf2 contained samples the FIR filter acting as a low pass FIR supplied with filter coefficients of value 1 in order to the sampling rate of the received samples by a factor of m to reduce; this is done in such a way that by means of the FIR filters in cooperation with the output buffers Buf3 an addition of m using a frame of the transmitted sample values.

  • a resampling of the transmitted data takes place in the protection or field device Samples instead. Since there are no processors in the signal path (Microcontrollers, digital signal processors, ...), finds no temporal influence on the samples through interrupt latency times. The entire signal preprocessing happens exclusively by synchronously clocked Logic. Thanks to high sampling rate rates (> 2 M samples / s) and high transmission rates (> 120 Mbit / s) affect the transmission of the digital measurands for the digital protective device (1 ... 5 ksamples / s) temporally transparent. The attainable Phase error is less than 0.1 °.
