Analysis of the regulatory support for the efficiency of systemelements of low-potential complexes at power plants

Abstract

The article analyzes the existing regulatory and methodological support for the efficiency of
elements of low-potential complexes (LPCs) of thermal and nuclear power plants, which include
capacitors, circulation and condensate pumps, ejectors, automatic control systems for individual equipment, and the general control system of a low-potential complex. The role of the system of the
low-potential complex in the overall balance of the power unit of the power plant according to
various water supply systems was determined. There was conducted an analysis into the existing
normative-technical and normative-methodological documentation with regard to the presence of
normative methods for ensuring the efficiency of the systems of the low-potential complex of
thermal and nuclear power plants and its main elements, which would be guaranteed to be able to
ensure minimal total energy losses in compliance with the necessary indicators of reliability,
environmental friendliness, safety, etc. It was established that the existing regulatory and technical
documentation contains methods and techniques for calculating the energy efficiency of individual
elements of low-potential complex systems, but there is a lack of methods and algorithms for
determining the parameters of elements of low-potential complex systems that ensure maximum
energy efficiency both in the nominal operating modes of power units and in the entire range loads.
The universal normative methods of structural-parametric synthesis of energy-efficient regulators of
automated control systems, which would be guaranteed to be able to provide high accuracy
indicators of maintaining the necessary parameters of the elements of LPC systems, have not been
sufficiently formulated. Demands have been put forward to improve the existing normative and
technical documentation, namely: to formulate universal normative methods of structuralparametric synthesis of energy-efficient control systems for the elements of the LPCs according to
the criterion of minimum energy losses, system and quantitative indicators, as well as methods and
means of their guaranteed technical support.
