Melnykov V. Providing of electric power quality of hydro-generators by creating precision frequency and power control systems

The object of the research is the processes of ensuring high indicators of the quality of electricity generated by hydroelectric power plants of hydroelectric power plants. The purpose of the study is to improve the quality of hydraulic power plants, by improving scientific and regulatory methods that provide high static and dynamic accuracy of automatic control systems of hydrogenerator plants. Scientific novelty of the results: proposed and scientifically justified methods for ensuring high accuracy of automatic control of the frequency and power of hydroelectric plants of hydraulic power plants based on solving inverse problems of dynamics and compensating for errors caused by non-linear characteristics of control objects, which improved the quality of electricity; Mathematical models of automatic control systems of frequency and power of hydrogenerating installations, methods of structural and parametric synthesis and optimization of electrohydraulic systems of automatic control, which allowed to perform a refined analysis of the influence of various technological factors on the quality indicators of electricity produced by hydrogenerator sets, were further developed; The methods for determining the regulatory parameters of the systems for regulating hydrogeneration installations based on solving inverse problems of dynamics have been further developed, which has improved the energy efficiency and quality of electricity produced; for the first time, structural-parametric synthesis and optimization of precision frequency and power regulators of hydrogeneration plants were carried out based on solving inverse problems of dynamics, the relationships obtained to determine their optimal parameters, which allowed the development of regulatory support for improving power quality
