The modelling of control segment of concentration aluminum oxidee in aluminium electrolysis cells with baked anodes are described in this article. The base of research is the model development of the installation. The modelling is executed in software package MatLab ® 6.5 with using visual design program Simulink and structural diagrams of conditions and transitions StateFlow. Figures of aluminum oxide concentration, fluoride salts concentration, temrerature of process, expect voltage are results of this work.
Management of technological process of smelting of aluminium is one of the most complex technical problems at whom in a mode of real time on two parameters it is necessary to trace, process, analyse in time the information and to undertake necessary actions. Management of technological process should be reliable and predicted, with the minimal operational expenses at maximal use of accessible resources.
Processes of aluminum electrowinning are frequently accompanied by magnetic and hydrodynamic instability. This phenomena leads to deterioration of the process characteristics and has to be compensated by a corresponding control system. The paper gives a summary of data processing on operation of a subsystem designed to detect and compensate metal agitation and describes a trend in software for automatic process control systems to compensate magnetic and hydrodynamic instability.
Oil, coal and gas are currently the main energy resources in the world. However, their reserves are not unlimited and are rapidly decreasing. Under these conditions, the problem of energy saving becomes acute, which can be solved by using wind energy as a source of energy. Wind energy can be utilized by means of wind power plants. The article deals with the peculiarities of wind generators application. Brief descriptions of wind power plants developed by teachers and students of the G.V. Plekhanov Leningrad Mining Institute together with employees of the St. Petersburg Institute of Mechanical Engineering are given.
