Abstract :
The paper presents analysis of operational conditions of auxiliary electrical system of power plant during load shedding by generation unit. Load shedding of power unit refers to the situation in which generation unit is disconnected from a grid when frequency falls below preset level and power unit safeguards auxiliary service supply in order to be able to restore power system after its blackout. Detailed analysis of auxiliary power system operation is advisable for operational reasons. The paper presents results of simulation performed for 360 MW power unit during load shedding. Matlab-Simulink environment has been applied to prepare simulation.
