Abstract

A system for real-time verification of protective device system configuration settings on a monitored system, is disclosed. The system includes a data acquisition component, a virtual system model database, a protective device system verification engine. The data acquisition component is communicatively connected to a sensor configured to real-time protective device configuration data output from a protective device that is part of the monitored system. The virtual system model database is configured to update a virtual mode of the system based on the status of the protective devices and to store a virtual system model of the monitored system, including preset protective device configuration settings for the protective device. The protective device system verification engine configured to monitor the real-time protective device configuration data and the preset protective device configuration settings and generate a warning when there is a difference between the real-time protective device configuration data and the preset protective device configuration settings.
