A risk management model for improving operation and maintenance activitiesin electricity transmission networks

in this paper, we formulate a risk management model for improving operation and maintenance activities in electricity transmission. The model is based on the five core elements of risk identification, risk measurement, risk a ssessment, risk evaluation, risk control, and risk monitoring and is applie d to an actual case study of improving equipment availability of an electri city transmission network through proper operation and maintenance of 440 k V switchgear. We find that the model can be applied effectively in identify ing and assessing potential risks and developing appropriate corrective act ions to contain and control the identified risks efficiently.
