MARS: an aid for network restoration after a local disturbance

The MARS system has been designed to generate restoration plans in the case of a local disturbance, leading to the loss of power supply on a limited number of HV or EHV substations. A restoration plan is a sequence of discrete actions on the network. To construct these plans, the operators must take into account general restoration guidelines or local constraints, but most of the procedure relies on their experience. The aim of the MARS project is to provide the operator with an aid during these delicate phases of network monitoring. MARS is a second-generation expert system which takes into account man-machine cooperation. Organized around a blackboard architecture, it integrates planning knowledge sources containing the restoration expertise, a qualitative model to predict the results of the considered actions, and a quantitative model to verify the correctness of the plans.<
