Iunieieva N. Simulation of electrical power systems (EPS) with microprocessor devices to ensure EPS stability

The object of research: stationary and transient processes in electric power systems. The purpose of research: development of mathematical models and software for improving protiavariynogo control of power systems, equipped with a microprocessor register settings, emergency control and regulation to ensure stability of EPS.s. Methods of research: theory of electrical circuits, the elements of the regression analysis, mathematical modeling of dynamic processes, numerical methods for solving problems in dynamics, simulation, analytic geometry unit, programming techniques in a software development environment Microsoft Visual Studio. Theoretical and practical results: the method of monitoring of the current static margin in the EPS based on the existence criterion of the phase synchronized measurement mode in the remote sites of the electrical network with the visualization of the loading path is proposed. The simplified mathematical model of thermophysical processes in NPS with VVER for long-term dynamics calculations in complex EPS is created and software implementation and verification of the formed model is performed by using the full-scale processes. The algorithm of simulation of microprocessor device for automatics for elimination of asynchronous operation (AEAO) with rectangular characteristics of resistance elements is developed. Degree of introduction: are used in the design and analysis of stability of industrial software system by means of which the adjustment of AEAO on the communications links of the Tashlyk HPSPP with the South Ukraine NPS is made. Effectiveness of implantantation: improves the accuracy of calculations of both static and dynamic stability of power systems. Sphere of use: electrical power systems.
