ABSTRACT
Energy saving and renewable resources’ effective usage is the need for Kazakhstan’s sustainable development. In article modern conditions of legal framework of Renewable energy sources’ usage in Kazakhstan are described. Analysis of governmental program realization in Kazakhstan for development of Renewable energy sources’ usage is included. Because of geographical, climatic and social factors agricultural formations are the most perspective consumers of Renewable energy in Kazakhstan. The analysis of electric optimization problem in Kazakh’s agroformations has shown: the solution of such task isn’t simple, but multi-factorial. According to the last agricultural census more than 40% of agroformations is not connectable with the power lines, including only 1% that has got an autonomous source of power supply. The intensive equipping of groformations began with wind turbines installing in the 1990s, but haven’t shown good results because equipments were selected not according climatic and operational conditions, without effective storm protection and efficient service of technical maintenance. Research purpose was to develop methods of rational parameters’ choice according to climatic and operational conditions at Kazakh agroformations for wind power equipment as autonomous power supply system. The estimation criterion of optimal composition of autonomous power system is offered. The algorithms of optimal parameters choice for autonomous power system with software packets for choosing wind power plants rational parameters according to climatic and economy’s operational conditions are developed. Work’s practical value consists in adaptation of the system’s substantiation technique to specific conditions of formations. It allows considering almost all the factors influencing on plant’s work, and at the same time accelerates calculations and submits them in a convenient format for equipment choice. Research methodical basis is the complex concept to describe of functioning autonomous power ystems for agroformations, and wind power plants operations in aggregate with thematical decision making methods that allows to raise efficiency and reliability of tasks solution. Information basis of work consists of statistical data from eteorological stations, technical characteristics of serially let out wind plants, their elements and accessories, experimental data. Methods of data analysis and searching optimization, the accidental processes theory, computer software Excel, TATISTICA and MatLab are used. Work results are taken as development principle for WE-5Т-2М wind power plant’s pre-production model, model samples of wind power plant’s with capacity between 5…8 kW.
