Group control of air-cooled gas apparatuses

Abstract

The paper considers the possibility of reducing electric power consumption by aircooled gas apparatus of a gas compressor station. The authors propose a system with breakdown of ventilators into IV groups with five ventilators in each group. Comparison of operation modes of a traditional cooling system and a grouped one with fans speed regulation on the basis of a frequency converter showed that the grouped handling system saved up to 40% of electric power.

Assessment of effect of lining material on energy efficiency of starting up ball mills

“…The influence of the dynamic parameters of a drum mill can be considered most fully on the basis of an adequate mathematical model, where transient processes in a synchronous motor are described by the complete Park -Gorev equations [5][6][7][8]…”

Method development for determining the energy-efficient mode of air-cooling devices’ operation

“…The algorithm for dividing the system of air conditioning devices into groups and achieving the possibility of controlling three groups at the same time using one frequency adjuster is presented in Figure 2 and in the formula (1) [4]. The group frequency control structure of fans of ACD system is described.…”

Study on energy consumption regulation of devices in industry enterprises

“…Energy services have received far less attention from the industrial sectors, and especially from industrial enterprises [3,4]. A number of achievements are achieved as a result of monitoring the changes in energy consumption of devices used in industrial enterprises separately or in groups based on their performance characteristics [5][6][7][8]. These include the prevention of major damage caused by some small damage to the equipment used in the enterprise, the reason for the increase in energy consumption from the limit value, and the increase of the service life of the electric machine.…”
