There is presented least squares method for predicting the parameters of the regime of electric power systems. It is shown that, based on the least-squares method, it is possible to obtain prognostic equations, aswell as coefficients of approximating functions necessary for the formation of these equations. The results of the analysis of the comparison of linear, hyperbolic, logarithmic, exponential and quadratic functions on the use of LSMs to predict specific fuel consumption are presented. Analytical studies are based on statistical data on specific fuel consumption for the period 1990-2016 years by the power system of Uzbekistan. There is shown that the statistical data was divided into training and control samples, when performing an analysis of comparisons of algebraic functions. The training sample, which based on prediction equations are obtained using algebraic functions of various types.

The possibility of controlling the operating modes of various installations amplifying electrical signals using optothyristors is presented and the ways of their inclusion in electrical circuits are presented. The optoelectronic contactless voltage relays were tested in laboratory conditions to obtain an input-output characteristic and a form of capacitance voltage. Based on the improvement of the proposed circuit, a circuit of an optoelectronic contactless voltage relay is developed and provide a high degree of reliability. The simulation of the proposed voltage relay circuits is performed using the MATLAB R2014a program, the results of which show that changes in the shape of the output voltage curve are close to a sinusoid and coincide with the results obtained analytically. As a result the obtained conditions of use make it possible to obtain a voltage with a sinusoidal shape on the load and achieve a relay return coefficient close to unity.","PeriodicalId":22199,"journal":{"name":"Technical science and innovation","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82025777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tasks of overcoming uncertainties arising in the process of operation of technological units at the enterprises of the cotton-cleaning industry are presented. An example of solving such a problem by using an artificial neural network is given. Mathematical models based on the neural network have been developed that are used to formalize the process of drying raw cotton and determine the optimal tuned parameters of the fuzzy-logical PID controller, allowing the fate of changing the operating modes of the technological units of the drying drum. A method for determining the number of synoptic weights of artificial neural networks is proposed, which minimizes the number of trainings and increases the speed of management decisions. To train the neural network weights use the reverse spreading error method. The range of variation of the regulator parameter is justified, taking into account the features of the cotton drying process. As a result, the proposed model was used in the control system of the drying process in terms of quality indicators, which led to an increase in the accuracy of the technological process.","PeriodicalId":22199,"journal":{"name":"Technical science and innovation","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90722329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
