摘要: The aim of the invention is to provide operating personnel a control centre an electrical energy supply in suitable manner with information about any oscillations that have occurred network. Said achieved by method for generating signal indicating oscillation variable In said method, state characterising calculated from measured values current indicators and/or voltage indicators. If exists, amplitude characteristic value (A) course and damping (xi) are additionally determined. position particular pair consisting associated compared hazard ranges, which present range (44a-c) indicate level network, determine parameter, output on basis parameter.
