Abstract:
The development of power engineering, under current conditions, is aimed at the use of distributed generation plants in power supply systems located in immediate proximity from power consumers. The article deals with power supply system with turbo generator plant and high power energy storage unit. Description of a power supply system model with turbo generator plant, energy storage unit and asynchronous load is provided, and modeling results of power supply system transition to the isolated operating mode. The model of the power supply system under study was carried out in the MATLAB environment using the Simulink and SimPowerSystems simulation packages. In work is a description of the PSS model used with DG plant and ESU, as well as the simulation results. Based on the computer simulation results the conclusion, that use of prognostic controllers turbo generator plant allows improving the damping properties of the system when switching to an isolated mode of operation.
