Оцінка експлуатаційної надійності систем автоматичного керування біогазовими установками

Abstract

The issues of ensuring the reliability of the control system of a biogas plant should be given special attention in the design of the system, in the manufacture of all hardware, in the development of mathematical and software, in the creation of information support, during installation and commissioning, during the technical operation of the system. A research aim is development of measures on providing of operating reliability of the systems of automatic control by biogas plants due to their optimal service. The choice of the optimal strategy allows you to achieve the best results from the operation of biogas plants without attracting additional resources. The importance of the early resumption of the operation of control systems after failures, as well as planning and organizing their effective preventive maintenance, is noted. The need for collection, processing, analysis and use of data on the reliability of control systems is noted. According to the obtained values of failure time and recovery time, the values of the readiness factor for devices of each type and for the control system as a whole are determined. Analysis of the obtained data on failure time, recovery time after failure, readiness factor will allow to develop organizational and technical measures, the implementation of which will increase the operational reliability of the control system of the biogas plant. To assess the reliability, a complex integral indicator is proposed that characterizes the state of normal functioning of the system. Changing the strategy of preventive maintenance and the organization of work to restore the operation of system devices after failures, based on the analysis of the value of the coefficient of normal functioning, it is possible to obtain the necessary values of the reliability of automatic control systems for biogas plants.
