A distribution network in supply chain management increases product reachability and handling density across different warehouses customers. Relays the prevent congestion, stagnancy, delayed deliveries. Protecting relay functions streamlining them are tedious due to varying vehicle goods densities. This article introduces a populous scheme (PRMS) for multi-access delivery networks address probl...

In relay protection devices with information digital processing the input controlled values are currents and voltages of protected object received from traditional measuring transformers, which converted into voltage signals using appropriate converters. To limit frequency spectrum these subjected to preliminary analog filtering, after they discretized in time a desired step Δt quantized by lev...

Abstract At present, the conventional localized equipment calibration technology mainly adopts manual way to check parameters, which leads low accuracy due lack of analysis error sources. In this regard, for substation relay protection considering electromagnetic interference is proposed. The value calculated by simulating a high-precision unit, designing pre-circuit fast voltage and current sa...
