Abstract:
1. A method for determining in real-time the bracing capability of a protective device in a monitored system using a virtual model used to simulate the monitored system, comprising: receiving real-time sensor data for the monitored system including for the protective device; generating predicted operational values for the monitored system including for the protective device based on the virtual model; performing a short circuit analysis for the protective device using the predicted operational values; calculating an adjusted short circuit current for the protective device based on the short circuit analysis; determining a bracing capability for the protective device; determining whether the bracing capability is greater than or equal to the adjusted short circuit current; receiving further real-time sensor data; and comparing the predicted operational values to the further real-time sensor data; and determining based on the comparison if there is a change in status for the protective device based on the real-time sensor data, and when it is determined that there is a change in status, then updating the virtual model accordingly.
