Features of Constructing Information Models of Power Electronics Devices as Part of a SCADA System

The paper proposes a concept of introduction and realization of the extended information model (EIM) of electric power facilities as part of SCADA systems. Implementation of EIM provides data verification from sensors of power electronics devices as part of power grids connected to a single SCADA-system, which leads to a reduction in the impact of sensor measurement errors in power facilities, as well as allows you to diagnose sensor failure. The essence of the method is the use of mathematical models of electric power objects together with real sensor readings. The peculiarities of software implementation for reconciliation of mathematical model parameters with real sensor readings are considered. An example of EIM realization as a part of SCADA system and reactive power compensator based on AC voltage regulator is given.
