Substation Equipment State Transition Probability and Its Main Constraints
The traditional RTF (Run Till Failure) has not been applicable for the enlarging scale of modern power grid.For cutting the labor costs,it is essential for the future grid operation and maintenance to assess the condition of main power transmission and transformation equipments in the process of equipment operation,and establish the mathematical model for CBM (Condition Based Maintenance),and scientifically arrange the substation equipment maintenance plan.This paper views that the equipment state transition model has the properties of Markov chain,and the equipment state transition probability is discussed.And starting from the actual production,it mainly analyzes the three boundary conditions for CBM modeling:the grid risk,maintenance cost and environment condition.Combined with the usual equipment risks,cost calculation and climate impact,this research conducts the relevant mathematical deduction,with a view to guiding the preparation of overhaul plan.The simulation calculation will be made based on the above model in order to demonstrate the actual effect of the state model.
