Eberle, A.
In the future, stricter requirements will be put in place for the economic management of distribution networks. The required optimization processes in the distribution networks correspond to those that have already been started in the superimposed networks.In addition to production systems, highly-automated production systems with interfaces to the distribution network are used by customers. Furthermore, additional compensation units for reactive current compensation are installed in the distribution networks. All in all, this leads to a new load situation for the distribution networks. With the help of the DMR-D dynamic monitor, weak spots can be identified and a new form of network service can be provided. The information from the DMR-D can be used, for example, as an input for scenario planning or scenario controls for distribution networks. Data compression via the DMR-D also creates an ideal basis for communication between processes and service personnel, as well as between processes and strategic asset management. The development of damping measures over time and the Lyapunov exponents form the criteria for monitoring the network dynamics. The larger the Lyapunov exponent, the "quicker" the network will reach the critical management steps. In marginal cases the network will become unstable.Those new dynamics responsible for these error functions can generally not be identified by the conventional safety system.- Monitoring the damping profile of the network- Real-time calculation of the Lyapunov exponents- Warning critical damping reached can be generated with at least three DMR-D devices- Fault recorder function- SCADA Integration according to IEC 61850
