Development of phase-shifting complex for an ultra-high voltage network

Introduction. Rapid development of remote control and digital technologies in the energy sector is driving the introduction of new approaches and methods in energy system management. One of the directions of development of the energy complex is to increase its stability and reliability. To accomplish this task, technical solutions have been developed in this work aimed at increasing the efficiency of the phase-shifting complex with thyristor control and integrating the device into the structure of the electrical network. Thanks to thyristor control, it became possible to immerse this complex in the structure of remote control of the power system, which allows it to be used for operational and emergency management. The developed solutions are currently relevant. Goal. Investigation of existing phase-shifting complexes and development of a thyristor control circuit and algorithm. Materials and methods. The research is based on the analysis of the operation of existing phase-shifting systems and their control algorithms, the creation of a model in the software complexes MatLAB and RastrWin3 and the study of their influence on the parameters of the electric power regime. Results and discussion. In the course of the work, significant advantages of the thyristor control system were discovered, allowing the introduction of a phase-shifting complex into the structure of a complex ultrahigh voltage network, as well as the use of this complex in emergency management. Conclusion. Based on the results of the study, it can be concluded that the developed phase-shifting complex with thyristor control effectively regulates the flow of active power through the ultrahigh voltage network, increases the stability of the power system and increases the reliability of network equipment. Based on the results of the conducted research, further goals have been outlined for the development of methods to increase stability through the use of phase-shifting complexes.
