Voltage Regulation in The Lighting Nodes of the Electrical Workshop

Abstract

The object of study is the Novosibirsk Concrete Products Plant. This plant is characterized by a large plant area and the huge distance between the workshops, which results in a significant voltage drop in the low-voltage distribution network, especially in the lighting systems. For a more detailed voltage quality analysis, one of the most remote workshop was chosen. The purpose of the work is to determine the effects of voltage deviation on the performance of lighting sources and to consider existing solutions for eliminating the negative consequences of deviation, as well as the design of natural and artificial lighting systems. This paper considers the effect of voltage drop on parameters such as electrical energy consumption and changes in illumination level. In order to design the lighting system, I have done a feasibility analysis for all considered types of luminaries and voltage stabilizing devices, after I have selected several options with the optimum performance. Once the artificial light sources had been selected, I proceeded to design the lighting system. After I have analyzed the designed system on changes in energy consumption and illumination level in the working place during each month. Further local voltage regulation in lighting networks was considered. It was followed by a technical and economic analysis of the implementation of these technologies, after the optimum lighting configuration meeting all conditions was selected. All calculations are based on the plant load data, daily load diagrams for minimum and maximum operation modes, as well as on existing researches in the field of voltage deviations effects on the operation of electrical equipment. In this paper, the technical part consists of calculations of the window dimensions for natural lighting, selection of the luminaires amount for artificial lighting, calculation of the voltage deviation and the illumination level changes. The economical part consists of the calculation of net present value, equivalent annual payments, and sensitivity analysis of these indicators.
