Abstract

It is known, the nature of electricity consumption generally is determined by the nature of consumption of its individual mechanisms. The process of obtaining sawn timber at sawmill is on separate flow lines. Therefore, energy consumption in total energy expenditure is defined as the sum of individual lines. In order to reduce consumption and improve energy efficiency it is necessary to ensure the employment of flow lines in a sustainable, energy-efficient modes. This can be achieved through dependency analysis of energy consumption by line from a variety of factors, evolving in the process of getting sawn timber. The purpose of this article was to build the energy characteristics of the flow line of sawn timber as an energy performance of mechanisms within the line and connected by a single processing. Work of the flow line is connected with the impact on them of various random factors, so energetic characteristics are straightforward depending on technological factors and therefore they are received as correlations. To its building the flow line is presented as а multistage queue, for which is used the simulation modeling of technological and energy processes. As a result of the studies was developed the simulation model of sawmilling processing considering random factors. For sawmilling workflow energy characteristics have been received as а correlations that measure main parameters power consumption depending on the flow capability. The energetic characteristics availability will allow better planning of energy discharge intensity for each type of logs and production in general. It has been found that the energy characteristics of the main indicators of power consumption of the flow line are non-linear. It has been shown that the process of modeling and energy characteristics reception can be simplified if we take into account that the total energy consumption of the flow line more than 92% of which are energy-intensive mechanisms: barking machine, two saw mills and two cutting machines. Therefore, analysis of energy consumption of the flow line, determination of the most efficient modes of work with a relatively high degree of precision are conveniently and advisably conducted by fast-track energy characteristics, without distorting the real patterns and at a significantly smaller amount of basic data.
