Abstract

An efficient and reliable data link is indispensable for the optimum implementation of the constantly growing need for building, extending and operating smart grids. The monitoring and control of remote components calls for comprehensive availability of measurement data and information to guarantee reliable overall operation.

In order to adapt this type of data flow to provide an optimum fit with the processes required, it can often be helpful to intervene in the control and distribution of specific transmission processes or to regulate them suitably. The acquisition and the recording of network disturbances and properties are an essential element within power generation and distribution. However, because appropriate recordings do not necessarily always have to be made available immediately, a wide range of different approaches present themselves for adapting the transfer and distribution of recordings to fit in with overall data traffic.

The approaches described in the technical paper for improving and regulating data traffic and data volume between fault recorders and a central computer can also be used in various different combinations to provide very good ways of making recorded fault and long-term data available as needed. In addition, by choosing sampling rates, recording times and trigger criteria during the configuration of the fault recorder itself, the number and size of fault records can be suitably adapted in advance.
