Extraction Steam Flow-generator Power Modeling and Its Application in Wind Power Consumption

Due to the randomness and volatility of wind power, the regulation capacity of power system is insufficient after large-scale grid connection. After the heating transformation of pure condensing thermal power unit, its regulating capacity has changed significantly. Therefore, the technical research of test and theoretical modeling is carried out. The minimum power value of the generator under steam extraction condition is tested through the test, and then the maximum output power value of the generator is obtained by considering the power loss caused by steam extraction. In this way, the steam extraction flow electric power model is obtained to calculate the regulating capacity in real time. According to the online visible regulation capacity, this can guide the stable operation of the power grid. This can be used for reference to promote the development of wind power.
