Development of automatic control system of fan electric drive for underground coal burning

Purpose of the work: determination of the dependence of the characteristics and state of the technological process of underground coal burning on the operating conditions of the fan unit electric drive for development of an automatic control system of the fan electric drive to ensure the prescribed level of the process quality and normal conditions of operation of the equipment. The theoretical results of the work include the development of a mathematical model of the technological process and formulation of its control principles; proposal of a method identification of the dynamic elements of the fan unit electric drive control system; determination of the equation of the interconnection between the parameters of the transfer function of the system portion being identified and the results of the identification procedure. Developed are a method of calculation of the operating conditions of the fan unit and its electric drive during the technological process control; structural patterns of the fan unit electric drive control system which provide for the stabilization of the thermal power of the underground heat generator; procedures for the identification of the control system elements; adaptive control systems. The mathematical model of the technological process and the structural scheme of the electric drive control system are adopted for introduction at station "Podzemgaz"Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
