Physical Modeling Analysis Based on Fan Characteristics

For the conventional power system voltage stability study, the voltage instability or voltage collapse is started from the load point of the receiving system. Because the load demand exceeds the limit of the transmission power of the power network, the system has been unable to maintain the balance between the power of the load and the power absorbed by the load. The system loses balance and causes voltage instability. In view of the characteristics of wind power generation, many aspects have been affected by the traditional generator sets to the power grid, and the impact of the grid on the wind turbines has changed. According to the characteristics of wind turbines, it is necessary to study the problems of wind farms connected to power grid.
