Davydenko L. The scientific bases of complex monitoring of the energy efficiency of facilities of water supply enterprise

The thesis is devoted to solving the problem of energy performance improvement of the facilities of the municipal water supply enterprise by development of the theory of monitoring of energy efficiency and integration of its procedures and results of their application in energy management system taking into consideration technological features of functioning of water supply facilities. The mechanism of evaluation of energy performance, which is based on the concept of benchmarking, was proposed. It provides quantitative and qualitative estimation and classification of facilities by construction of energy efficiency limits as separating surfaces (including constructed taking into consideration the artificial standards formed based on the best values of indicators of real objects). It allows taking into consideration the operating conditions of the facility, assessing the energy performance, forming tasks and identifying ways to improve it. A procedure for power consumption planning of water supply facilities was developed. It is based on the usage of a set of multifactor models of power consumption and the results of a formalized description of water supply, which provides a definition of the energy baseline adapted to the fluctuations of the water supply process. The models were built for typical operation conditions of the facility by group consideration of the relevant variables of the energy baseline. The set of variables is formed taking into consideration the significance of the influence of variables on the power consumption, their variability, measurability, and ability to control. The mechanism of monitoring of fluctuations of water supply caused by influence of seasonal, climatic and social factors was proposed. It provides classification of daily water consumption charts by means of the constructed classifiers and forecasting of daily water consumption and a profile of its daily chart. This allows performing a description of water supply for typical operation conditions of the facility and take into consideration the influence of abnormal climatic factors. The mechanism of control of power consumption efficiency of water supply facilities was proposed. It provides control of power consumption, technological parameters of water supply, energy efficiency indicators, climatic factors and detection of moments of change of operation conditions of the facility. This makes it possible to identify the fact of changes in power consumption efficiency, the reasons that caused it, the change the energy performance, to establish the need to adjust the planned values of parameters of water supply and energy baseline. The principles of the organization of information support of energy management, which provides integration of results of benchmarking, planning and control of power consumption and formation of uniform information space of complex monitoring of energy efficiency of facilities of water supply system, were proposed.
