STRUCTURAL SYNTHESIS OF PRECISION SYSTEM OF AUTOMATIC REGULATION OF FREQUENCY AND POWER OF HYDROTURBINE
Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 2
Abstract
The provision of efficient automatic regulation of hydraulic turbines is an important and urgent scientific and technical task, the solution of which will increase the technical and economic characteristics and reliability of hydraulic units, as well as the frequency stability of the electric power generated by hydraulic power plants. The article is a structural synthesis of the frequency and power regulator of a hydroturbine based on the solution of inverse dynamic problems. This controller significantly reduces all types of static and dynamic errors and, thereby, improves the accuracy of regulation and the quality of electricity produced. To perform the structural synthesis of the precision regulator SAR Ch and M of the hydroturbine, simplified linearized mathematical models of the actuator have been developed that take into account all the basic functional relationships and parameters that affect the quality control parameters. Based on the results of experimental studies, numerical parameters of the developed models are determined. On the basis of the solution of the inverse problem of the dynamics of the CAP C and M of a hydroturbine, a structural synthesis of a universal precision regulator capable of compensating for static and dynamic control errors is performed.
