Operational Reliability of the Equipment in Individual Heating Substations

Heat and power efficiency of functioning of individual heating substations largely depends on the well-coordinated operation of the equipment, which is characterized by heterogeneity of qualitative signs of efficiency. An important aspect of choosing a set of equipment is to ensure the reliability of its operation. At the same time, ensuring a higher level of reliability requires higher economic costs. The aim of the study is to assess the reliability of equipment in individual heating substations. The assessment of reliability indicators of individual heating substations is carried out on blocks of the equipment with use of a method of «the logical scheme of failures». Subsequent analysis based on the theory of reliability makes it possible to give a quantitative assessment of qualitative characteristics of the technical condition of the equipment at a limited amount of statistical information. Numerical indices of failure rates and probability of trouble-free operation of circulation pumps of heating systems controlled from individual heating substations are determined.
