Simulation of power assets management process

Abstract

Implementation of the Industry 4.0 concept leads to in-depth end-to-end automation of all activities of an integrated power grid and requires fundamentally new technologies that change conventional business models. Operational assets of power grid companies are characterized by semantic, syntactical, structural and systematic heterogeneity, which hinders the interaction at all management levels aimed at accident prevention and performance improvement. A cognitive double-level ontological model was developed as an aggregate of the conceptual confinement model and a set of hierarchic confinement models of processes of technical condition diagnostics, repair program development and optimization, as well as optimization of logistic processes as the repair program is being implemented in a power grid company. A structural process scheme of distribution zone repair management in Q-scheme symbolism, generalized and detailed modeling algorithm schemes were developed. An interaction graph for components of the power grid repair management process was developed. Elementary components of the stochastic process of interaction of the repair management process elements were detailed by their sets of states. The sub-model “Consumption of consumable materials and resources”, realized in the Arena simulation package, was detailed. Examples were provided regarding the application of intelligent techniques at the strategical and operational levels of power grid management for structural synthesis of a balance scorecard system and identification of apparent defects of process equipment.
