description: The subject of the graduate qualification work: Â«Investigation of the stability of long-distance power transmission lines with controlled FACTS devicesÂ». This study is devoted to impact-controlled devices of reactive shunt and series compensation on the indicators of steadyâstate stability and different operating conditions of long-distance power transmission lines. The first part of the dissertation consists of an overview of FACTS devices used to improve the performance of long-distance at high voltages. These devices have recently been used in the power systems of many countries of the world, as evidenced by numerous projects, some of which are discussed in this chapter. The second part of the work gives an idea of the impact on the steady state of all possible combinations of operation system settings. The steadyâstate stability of the line is also investigated in a wide range of operating conditions with the use of compensation and generator control devices. In the third part, the aperiodic and oscillatory stability of a longâdistance line is investigated when adjusting the regulators of controlled reactive power series or shunt compensation devices simultaneously in several operating conditions. In the last chapter, a simplified model of the Brazilian power system with an AC inter tie is collected, combining two powerful energy pools for parallel operation, where measures are proposed that allow to obtain optimal indicators of the steadyâstate stability of power transmission. In the work, the language for modeling dynamic systems of the Modelica type and the MATLAB programming system are used. As a result, FACTS device control actuating path systems, and their impact on the steady-state operation of the power transmission line were analyzed. A model of a large power system with controlled devices of series or shunt compensation has been implemented. A set of measures has been substantiated to increase the maximum power transmitted through the line and to damp intersystem oscillations.
