In the power supply systems of railways (PSSR), which include distributed generation systems (DG), intelligent technologies for controlling modes are fully applicable. To form the necessary characteristics of the transient process, the DG installations must be equipped with automatic control systems, the optimal adjustment of which allows improving the quality of electricity and improving the reliability of the electricity supply to consumers. The article describes the technique of coordinated tuning of automatic excitation regulators (AER) and the rotation speed (ARRS) of synchronous generators in relation to the installation of a DG operating in the PSSR. A feature of the proposed methodology is the use of the following intelligent technologies: a genetic algorithm (GA) to optimize the settings of AER and ARRS; fuzzy logic for adaptive control of the coordinated tuning of AER and ARRS. On the basis of the simulation, the efficiency of using the proposed adaptive AER and ARRS control unit of the generator of the RG setup is shown, which consists in reducing the transient time and the voltage overshooting and rotational speed of the generator rotor, and in providing the necessary stability margin and in the system’s ability to maintain the standard voltage and quality of electric power at consumers at disturbances in system.
