Predicative model in the problem of the optimal choice of asynchronous motor protection means
Journal Title: Електромагнітна сумісність та безпека на залізничному транспорті - Year 2018, Vol 1, Issue 16
Abstract
The article is sanctified to date issue of the day of choice of facilities of defence of asynchro-nous engines working in the workshop electric networks of industrial enterprises with off-grade electric power. Possibility of presentation of energyeconomic model of asynchronous engine is shown as disjunction of predicates and application to them algorithms of recognition of patterns for a decision-making. Main dignity of new model is an openness and possibility of accumulation of knowledge about the modes of operations of electromechanics equipment. The special attention is spared to procedures of authentication and adaptation of predicate model on the basis of calculable experiment on an economic criterion. Method application of re-duction of description of characters allowed to accelerate the receipt of this model on the stage of educating in future to execute necessary structural transformations during her adaptation with maintenance of exactness of description of intercommunications between technical and economic sizes, qualificatory efficiency of work of electromechanics equipment in an electric network with different facilities of defence or without them. In the article is open up the processes of search of the best decision on defence of asynchro-nous engine, that is realized on the basis of known in science the algorithm of recognizing static optimization of the nonlinear objects presented by totality of predicates. This algorithm uses principle of local surplus. In conclusion is examined the mathematical vehicle, used for description of procedures of ed-ucating, adaptation, minimization of amount of predicates and optimization and also practical value of the results got during a design. As predicates are determined by totality of numbers that possess properties of relational models of data, then operations above them can be executed in terms α - algebras and realized in the environment of the database management system. The re-sults of calculable experiment can be presented both as tables and kept on electronic storage cells. For their practical use it is enough to estimate quality of electric power on a concrete enterprise and technical state of engine, and then, using facilities of the database management system to choose the expedient method of defence of asynchronous engine most economically.
