An algorithm development of a joint aerodynamic and mechanical speed control of the wind turbine

The article discusses non-electrical ways of ensuring the quality of electricity generated by wind power system. The algorithm of active aerodynamic control, which was established, based on the iteration in progress in rapidity. A method of determining gear ratio single-stage multiplier, which is used in conjunction with the position control of the blades, based on the calculation of lines of constant frequency. There are suggested some recommendations for the generalization to calculate the transmission and the varistor. Application of the developed algorithms is possible for research purposes in the modeling in Simulink of operation modes of the wind turbine with aerodynamic or joint aero-mechanical regulation of frequency and active power.В работе рассмотрены неэлектрические способы обеспечения качества электроэнергии, генерируемой ветроэнергетической установкой. Разработан алгоритм активного аэродинамического регулирования на основании итераций, ведущихся по быстроходности, а также методика определения передаточного отношения одноступенчатого мультипликатора, применяемого совместно с управлением положением лопастей, основанная на расчете линий постоянной частоты. Даны рекомендации по её обобщению для расчета коробки передач и варистора. Применение разработанных алгоритмов возможно в исследовательских целях при моделировании в Simulink режимов работы ветроэнергетической установки с аэродинамическим или совместным аэро-механическим регулированием частоты и активной мощности

Rational use of by-products in the processing of turkeys

A man's life, his health and work is impossible without full of food. According to the theory of balanced nutrition in the human diet should contain not only proteins, fats and carbohydrates in the required quantity, but also substances such as essential amino acids, vitamins, minerals in certain, beneficial to human proportions. In the organization of proper nutrition the primary role of the meat products. Turkey is the largest after the ostrich poultry are grown in Russia on an industrial scale. Undoubtedly, the leading positions on the market of poultry meat is chicken products, but in recent years Turkey meat is becoming increasingly popular. The processed by-products include liver, heart, gizzard, neck, feet, head, and corals. The highest mass fraction of Turkey offal is the liver, heart, gizzard. It was established experimentally that the output of the liver is of 1.23%, the output of the heart 0,45%, muscular stomach of 1.87%. The article presents data on the study of the chemical composition of the offal of turkeys, fractional composition of proteins, the assessment of the nutritional and biological value of byproducts. The objects of study are: offal (liver, heart, gizzard) broiler turkeys received at home as a result of slaughter and primary processing. Despite the fact that Turkey sufficiently studied in terms of nutritional and biological value, however, information information on evaluation of properties of by-products is not enough. However, according to our estimates, they have considerable potential in the development of innovative products for food, feed and medical purposes on the basis of deep processing of all resources

ROLLER BIT DRILLING OPTIMIZATION

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала.The article is devoted to the study of the features of the roller bit drilling process control under the uncertainty caused by a random change in the drilling rock properties. An optimization model is proposed to control the roller bit drilling parameters, using correction values of the axial force and bit rotation speed. A method for optimizing the operating parameters of the roller drilling process is developed, using correction values of the axial force and bit rotation speed, depending on the technical characteristics of the drilling rig and the physical and mechanical properties of the rock. The proposed method allows determining the maximum values of the bit life, drilling speed and their relation, corresponding to the optimal conditions of the roller bit drilling process, which are necessary for optimal control of the parameters of the proces
