Golik O. Process control automation by energy supply a farm from autonomous energy sources

Object of research - processes of production and consumption of electric energy in the conditions of farm power supply from independent power sources. The purpose of work is optimization of process control by farm power supply from independent power sources according to energy needs of a farm at the expense of development of the system of automation of process control which realizes rational control modes by process with use of the neural information technologies. Theoretical researches are based on methods: scientific generalization and ordering, statistical processing and analysis of data, mathematical analysis; and theories: decision-making, probabilities, electric fields, indistinct sets and neural networks. Pilot studies by determination of intensity of sunlight and speed of a wind were carried out by means of a digital weather meteorological station of. The settlement part and modeling of processes of research were carried out on personal computers, as by development and use of modeling and settlement programs, and packages of applied programs. Researches of input parameters of object of control of system of the automated power supply (energy needs of a farm and independent power sources - solar and wind power plants) showed that the system works in the conditions of uncertainty. Therefore for creation of system of automatic control by process of power supply it is expedient to use adaptive methods of control, in particular, the device of indistinct logic with the neuronetwork adaptation which gives the chance, in comparison with traditional methods of control over objects in the conditions of uncertainty to create the power effective renewable knowledge base of modes of functioning of system and to optimize structure of system of automatic control in the conditions of real time. Production tests of system took place in conditions of the state of emergency "AVANTE" (Kiev) on an example of a farm which is in Kiev region. Results of scientific researches are introduced by the Public scientific institution "The Ukrainian research institute of forecasting and test of equipment and technologies for rural production of Leonida Pogorelogo". The offered technique of definition of likelihood characteristics and laws of distribution of intensity of solar radiation is used in the state budgetary subject № 1Б68.09 "Development of the system of support of decision-making for effective use of solar modules in the conditions of Ukraine". Results of dissertational work are accepted to use in the Program of power efficiency of the Kirovograd area for 2011-2015.
