Main information
OHL Assessment and Risk Evaluation Based on Environmental and Inspection Data
2012
Azevedoetal2012
Electrical grid operators have been struggling in recent years to deploy new lines to meet increasing demands for transmission capacity and quality of service. .. The collection of historical data, together with the knowledge of asset characteristics and system operation conditions, is structured in a generalized relational database. .. Additionally, this model is being extended with a comprehensive set of different environmental, meteorological and geographic data over the years. .. A methodology to evaluate operational risk for a short-period of time was developed inside REN, taking into account the probabilistic nature of contingencies and their severity under specific operating conditions. This new methodology aims to provide control room operators with risk-based security indices for the following period (such as 1 hour). Risk indices provide an insight to operators of the network state and of the constraints that operators face.
