| description | The normalized accuracy of the installed measuring instruments determines the scheduled measurement accuracy of the daily active load of an industrial enterprise. To maintain it during operation, syntactic and semantic methods can be used to control the reliability of load measurements. During syntactic control, the state of measuring instruments that collect and process information about the enterprise’s load is diagnosed. Semantic control is based on the use of probabilistic characteristics of the measured load. The condition necessary for semantic control is the presence of information redundancy about the values of the monitored load. It is possible to control the load limit values (settings) when a priori information is known about the lower and upper limits in which reliably measured load values in normal operation of the enterprise may be contained. The article considers control methods that use a posteriori redundant information about the dynamics of load alterations in various sections of the daily schedule. These methods include monitoring by the first increments of the load, which characterize the speed of its alterations, as well as control using linear and nonlinear extrapolations of the first increments. The results of the analysis of probabilistic characteristics of the daily active load of the enterprise and its first increments, which characterize the rate of load change, are presented. The effect of probabilistic characteristics of the first load increments on the boundaries of making a decision about the reliability of measurements is demonstrated. A comparative analysis of the effectiveness of reliability control methods based on the first load increments and their extrapolated values has been carried out on the example of measurements of daily active load schedules of the “Minsk Motor Plant” JSC. |
