| Popis: | The purpose of the research is to develop a methodology for calculating voltage fluctuations when connecting new equipment with rapidly changing load using mathematical models of typical consumers of timber processing enterprises. The urgency of the study is due to the need to provide a methodological basis for possibility of connecting a new consumer with rapidly changing load to the system. The purpose of the research requires solving some problems. The most significant problem is to find a way to calculate voltage fluctuations and flicker doses when modeling the connection of the new equipment. Methods of experimental and theoretical research and methods of mathematical statistics and the probability theory were used to process experimental data. The most significant results were: obtaining a methodology for determining the possibility of joint supply of household consumers and rapidly changing load based on the analysis of electrical load schedules and calculation of voltage fluctuations; mathematical models of work of voltage fluctuations sources - timber processing enterprises, consumers of electric energy. The developed methods are based on the analysis of electrical load schedules; spectrum analysis of the range of voltage fluctuations; mathematical modeling of common connection of consumers. In the course of the research, it was concluded that the proposed methods provide the basis for making a grounded decision about the possibility of connecting a new consumer with rapidly changing load and to make a decision-making process more objective. |
