Bliznichenko E. Scientific and technical bases of power quality thermal and nuclear power plants

The object of study: the processes to ensure the stability of the frequency of the electricity generated by turbo generator units of thermal and nuclear power plants. Subject of research: methods and means to improve the accuracy of automatic control of turbine-generator units. As a result of the research, the following new scientific results: first scientifically justified and proposed guidelines to ensure the accuracy of automatic regulation of frequency and power turbine-generator power plants on the basis of the solution of inverse problems of the dynamics and compensation of errors caused by nonlinear characteristics of objects that provide a scientific basis to improve the quality of electricity produced by thermal and nuclear power plants; improved mathematical models of automatic regulation of frequency and power turbine-generator units by taking into account the main factors affecting the accuracy of the frequency control: forces and moments of dry and liquid friction in the friction pairs, dead, compliance and multimass mechanical elements expend - difference nonlinear characteristics, leaks and leakages the working fluid, which made it possible to identify the causes of the basic errors of regulation and the development of means of their significant reduction; for the first time on the basis of the developed mathematical models performed classification, detailed qualitative and quantitative analysis of the main components of the errors of frequency and power turbine-generator units, which allowed the development of unified scientific and technical solutions to improve the accuracy and quality regulation of electricity produced; first developed a unified structure of automatic regulators of frequency and power turbine-generator units based on inverse problems of dynamics and obtained ratio to determine their optimal parameters, enabling the development of regulatory support to improve the quality of electricity. The collection of scientific research is a system of scientific, technical and regulatory framework to improve the technical and economic indicators and resource the process of electricity production and its quality.
