description: In this work was conducted the study of electrical modes and stable operation of a complex electric power system 220/110 kV, consisting of a ring grid, a power station, radial overhead lines and connected through an autotransformer of the power station was conducted. The first step was to select the main electrical equipment: power transformers and autotransformers, generators and wire cross-sections of overhead power lines. The next step was to calculate the electrical operation mode of the system in normal and emergency modes. These calculations were performed in two ways: the "manual method" and with the help of "Rastr" software. During the calculation of the modes in "Rastr" there were obtained the results on the use of compensating devices in systems 220/110 kv. Both methods were analyzed, the differences and advantages of both methods were highlighted. Then the two-phase short-circuit earth-fault currents were calculated through using the method of symmetrical components at the point on the high voltage buses of the substation at the end of air line 6 and. And after that vector diagrams of currents and voltages were constructed. At the final stage of the work the electric power system was studied for static and dynamic stability to disturbances; special measures were taken to increase it. This part of the study was conducted in the software "Dymola", which proved itself as a result of many years of experience. According to the obtained results the optimization of the system was carried out, the time of damping of oscillations was reduced, the static stability was increased by setting the strong action of AVR, and also the experience of three-phase automatic reconnection of the line was carried out to assess the effectiveness of a widely used method of emergency response and to assess its impact on the stability increase in our system.
The work resulted in a complex electric power system which have static and dynamic stability within the limits of the values specified in regulating documents.
