METHOD FOR DISTRIBUTED WAVEFORM RECORDING IN A POWER DISTRIBUTION SYSTEM
摘要
An exemplary method and apparatus are directed to distributed waveform recording for fault monitoring and analysis of a fault condition in a power distribution system. One or more instrument transformers along with merging units and a plurality of Intelligent Electronic Devices (IEDs) distributed in a plurality of hierarchical levels. The distributed waveform recording corresponds to a fault event at different levels in the power distribution system data is carried out by at least two devices configured to detect an event for recording and perform waveform recording. The data used for waveform recording and the data for detection of the event are based on a single stream of the sampled measured value data and are thereby are time synchronized.
