Abstract
One method for increasing of power-transmission-line capacity is the use of series capacity devices. In addition, the use of controlled series compensation devices affects an electric-power system’s static stability. It is also widely known that automatic control of generator excitation has a positive effect on system stability. Thus, it is advisable to analyze the influence of a controlled series compensation device adjustable parameters on the line capacity when considering modes at the boundaries of stability areas, taking into account the automatic excitation of regulators on synchronous generators of a power plant. Methods of mathematical modeling of an electric-power system, the theory of long-distance power lines and electromechanical transient processes, and methods of analyzing the stability of electric-power systems were used. Original software in the C++ programming language was used as a modeling tool. Parameters of control laws of controlled series compensation device and an automatic excitation controller have been selected on the condition that static stability is maintained. Stability areas of the electric-power system under study have been constructed depending on the tuning parameters of the devices under consideration. A method for selecting complex control coefficients for devices to increase the capacity of a high-voltage power-transmission line is proposed. The proposed method for complex selection of regulation coefficients of controlled devices makes it possible to obtain their optimal values in a controlled electric-power system to ensure stability.
