Fedosha D. Development of method for forming the structure of the guild electricity radial topology

The object - power systems design guild radial topology. The purpose of the research - minimization of loss of electrical power in industrial power supply, allow recovery of electric energy consumers in the supply network, at the stage of forming the structure of the guild system in the design of power supply by improving the method of forming the structure of power of the guild. Methods: the theoretical electrical engineering to create mathematical models, numerical methods and methods of matrix calculus to solve the equations of mathematical models, methods of approximation and interpolation to ensure the sustainability of iterative processes, recursive methods of the theory of combinatorial optimization to find the power supplies. Theoretical results: for the first time on the basis of potential functions loads proposed a new formalization of problems of formation of structure of guild power radial topology, allowing the recovery of electric energy consumers in the supply network, this eliminates interference decision makers in the design process and makes it possible to obtain the structure of the shop mains with lower rated component losses electricity; has proposed a new method of determining the power supply power transformer for the indeterminate group of consumers of electricity, which is based on the optimization of energy efficiency power supply; took the further development of the method of potential functions loads of structure formation of the guild radial power topology in applying the new criteria for the formation of groups of consumers of electricity, than it is possible to use the method for systems of guild power, power-consuming equipment containing regenerative power to the supply network. Practical results: improved method of forming the structure of the guild electricity automates its construction, reduce the influence of subjective assessment of a person to make decisions and reduce design time. The implementation - the results introduced in the Southwest Power System (act introduction of 10.14.2014). and in the educational process Vinnytsia National Technical University (act introduction of 20.10.2014). The implementation - the results have been implemented in the State Enterprise "State Institute for designing of industrial Enterprises" (deed of implementation from 12.20.2013),and in the educational process Zaporizhzhya National Technical University in the department of "Power supply of industrial enterprises" (deed of implementation from)and at the Department of "Electricity" of the Institute of Energy Saving and Energy, National Technical University "KPІ" (deed of implementation from 20.03.2015). Sector (industry) use - power engeniring, power supply.
