Analysis Of Results

Developed in this work are the principles for creation of a system to control and governing the energy efficiency of solar panels providing power supply for LED luminaires. Realization of these principles allows the most efficient using the electric power generated by solar panels, to save in a real-time scale the data about system functions as well as provide a complex analysis of these data. Optimization of using the electric energy generated by solar panels will enable to determine the maximum possible power in each specific moment and to automatically tune its consumption. The complex data obtained with this system can be further used for not only statistical fixation of the produced and consumed electric energy in fact but also for prediction of the energy amount that will be generated by these solar panels in future.

The purpose of this study is to study the effect of loading power transformers (PT) in their continuous use on their energy efficiency on a real-life example of existing rural electric networks. It is noted that the vast majority of PT in rural areas have a very low load factor, which leads to an increase in specific losses of electric energy when this is transmitted to various consumers. It is planned to optimize the existing synchronized power supply systems in rural areas by creating new power supply projects in such a way as to integrate existing power sources and ensure the most efficient loading of power transformers for the subsequent transfer of these systems to isolated ones that receive power from distributed generation facilities. As an example, we use data from an electric grid company on loading power transformers in one of the districts of the Irkutsk region. Issues related to the determination of electric energy losses in rural PT at different numerical values of their load factors are considered. A computing device was developed using modern programming tools in the MATLAB system, which has been used to calculate and plot the dependence of power losses in transformers of various capacities on the actual and recommended load factors, as well as the dependence of specific losses during the transit of 1 kVA of power through a power transformer at the actual, recommended and optimal load factors. The analysis of specific losses of electric energy at the actual, recommended and optimal load factors of PT is made. Based on the analysis, the intervals of optimal load factors for different rated power of PT of rural distribution electric networks are proposed. It is noted that to increase the energy efficiency of PT, it is necessary to reduce idling losses by increasing the load of these transformers, which can be achieved by reducing the number of transformers while changing the configuration of 0.38 kV distribution networks.

This article discusses the problem of introducing more resource-intensive methods of generating electricity and heat, the main of which is the use of small-sized gas turbine units (GTU). The creation of a Mini-Thermal Power Plant on the basis of the GTU allows solving the problem of the shortage of heat and electric energy in certain regions, ensuring uninterrupted power supply to the housing and communal sector and industrial enterprises. This is due to the possibility of combined production of heat and electric energy, as well as products and services required in the municipal services of the city. This article presents ways to improve the energy efficiency of thermal power plants through the use of GTU.

A power system can be said to be reliable if it has a high continuity of service. To achieve this, an operational arrangement is required to optimize installed power to supply the load to avoid overloading or over-supply of the system. Modjopanggoong Sugar Factory Tulungagung is one of the sugar producing industries, where the electrical system in this factory uses two power supply, which is using PLN supply and Turbine Generator Boiler (BTG). The use of more than one power supply resulted in an increase in the required electricity production costs. To solve this problem, in this research will be conducted a study to make efficient of electrical energy cost which is done by arranging supply of electric energy, that is using maximum supply of BTG and its deficiency supported PLN supply (alternative I), using PLN maximum supply and its deficiency is supported BTG supply alternative II) and only use PLN supply (alternative III). The results showed that energy efficiency can be done with the regulation of energy supply at the factory, that is in alternative I with savings Rp.430.025.007 (2.1%), alternative II with savings of Rp. 553,984,815 (2.7%), and alternative III with savings of Rp. 2.055.727.407 (10%).

Modern Level

The modern level of agriculture is described by the introduction of renewable energy sources. New generation sprinkler machines are being put into production, in the power system of which solar panels are used. One of the factors that negatively affect the performance of solar cells in an open field is their dusting, which is formed as a result of dust storms and wind. Cleaning of the battery panels is carried out in various ways: manual, semi-automatic and automatic. Dust cleaning is included in maintenance. (Research purpose) The research purpose is to determine the conditions for performing the maintenance, which consists in cleaning solar panels in the field. (Materials and methods) Theoretical (analysis, hypothesis design), empirical (observation, testing), experimental (ascertaining experiment) methods has been used during research. (Results and discussion) The article describes an introduced parameter for estimating the level of dusting. The power loss indicator shows the ratio of the power of the dusted module to the power of the clean module. Unscheduled maintenance is affected by the distance of the solar module from the repair point, the power of the solar module, the loss from dusting, the frequency of maintenance and cost indicators. (Conclusions) It has been found the dependence of maintenance period of the solar module of the sprinkler machine on the distance to the sprinkler machine, to the point of maintenance and repair, the power loss coefficient in case of dusting of the solar module, the cost of performing maintenance, as well as the frequency of maintenance. Article describes the boundaries of the choice of operating mode of the sprinkler between unscheduled maintenance for cleaning the solar module and the acceptance of additional power of the sprinkler power supply system according to the criterion of minimum operating costs.
