METHODOLOGICAL APPROACHES FOR ASSESSING THE QUALITY OF MULTI-PARAMETER ENERGY FACILITIES

Abstract

The complex quality assessment of complex multivariate research objects is analyzed. It is emphasized that the current methodology for assessing the quality of multi-parameter objects, despite the heterogeneity of these objects, is based on common principles and methods of qualimetry associated with a particular system or group of systems that are part of this object and carry information on the quantitative parameters of the technological process and properties of the object but does not allow to determine a single integrated criterion for assessing the quality of the object. It has been found that when assessing the quality of a power facility, the main information and measurement systems do not have a process for forming comprehensive and integrated quantitative and qualitative indicators for assessing the quality of the facility. It is proposed to improve the information-measuring system of the software and hardware complex of the automated process control system of a power plant power unit, which, based on the analysis of individual quantitative and qualitative indicators of the quality of control and information flows (signals) on technological parameters, allows to establish and present the relationships between the structural elements of the facility and the process of forming the quality of electricity as the main quantitative and integral indicator of the facility quality assessment. The article substantiates the use of methods for assessing the level of electricity quality, which can be used both separately and in various combinations and allow: to ensure the obtaining of the final economic result, which allows making an economically sound decision in the production of electricity, and to more accurately assess the level of electricity quality when measured by various devices or when calculated are based on formulas that reflect objective laws. The stages of the sequence of work on the organization and conduct of qualimetric assessment of electricity quality are determined, which allows: to determine the purpose of assessing the level of electricity quality; to select the nomenclature of single and basic indicators for assessing the quality of electricity, as well as the choice of a qualimetric method for assessing the level of electricity quality. The application of instrumental (measuring), computational, and static methods of qualimetry, which allow calculations based on the values of quantitative parameters of electricity and can be used in practice when calculating the economic costs of electricity production at a power facility, is considered and substantiated.
