In addition to being communicatively connected to the data acquisition hub 112 and the client 128, the Transient Stability Modeling Engine 3002 can also be interfaced with the components of the power analytics server 116. The components of the electrical system 102 may relate to the static components and rotating equipment, as detailed above. For example, the stability indices data from the components can be indicative of the real-time ability of the electrical system 102 to sustain power demand and maintain sufficient active and reactive power reserve to cope with ongoing changes in demand and system disturbances due to contingencies, operate safely with: minimum operating costs while maintaining an adequate level of reliability, and provide an acceptably high level of power quality (maintaining voltage and frequency within tolerable limits) when operating under contingency conditions.
The Transient Stability Modeling Engine 3002 can be configured to process the real-time data output, the predicted data output, historical data output and forecasted aspects about the operation of the electrical system 102 to generate a user interface that can convey system security index values of the electrical system 102 to a user (i.e., electrical system 102 owner/system administrator/operator). In one embodiment, the system security index values can be the real-time operational performance of the individual components of the electrical system 102. In another embodiment, the operational state can be the predicted operational performance of the electrical system 102. In still another embodiment, the operational state can be a historical data trending display of the historical operational performance of the electrical system 102.
