SIMULATION OF ELECTRIC POWER SYSTEM SSSC BY METHODS OF INTERCONNECTED CIRCUITS FOR ANALYSIS OF LOAD DISTRIBUTION MODES OF TWO POWER LINE

When distributing loads between various sources of electricity and power transmission lines, it is possible to use SSSC. To calculate and analyze the distribution of active and reactive powers in the electrical equipment of electric power systems, mathematical and computer models have been built. The modeling was carried out according to the methodology for calculating systems by interconnected subsystems, which ensures the minimum consumption of computer time. One of the possible structures of the control system has been developed. The results of calculating electromagnetic processes in a specific electric power system with a voltage of 10.5 kV are presented. It is shown that SSSC allows one to realize only one control function, for example, to provide a given distribution of reactive power between two transmission lines. Other devices should provide other functions of stabilization of a given mode of operation of the system. For example, the stabilization of the load voltage and the distribution of the active power of the two transmission lines must be provided by the power sources.
