Inertia Evaluation of Wind Farm Under Overspeed Power Shedding Control

Abstract As the penetration rate of wind power generation gradually increases in most grids, it is necessary to evaluate farms’ inertia provide information for electric grids and boost grid stability. This paper firstly models control mode overspeed shedding, which can realize under operation different blade tip speed ratios, so that turbine has a high support capability. Then energy change process analyzed, virtual time constant derived single unit’s inertia. Finally, simple condition farm’s requirements day are simulated using an equivalent model, level farm calculated. The proposed research approach alleviate sophistication evaluation also effectively consider influence control.
