With the expansion of the scale of wind power generation, in order to improve the frequency recovery rate and stability of the wind power HVDC transmission system, this paper establishes a frequency coordinated control (FCC) mathematical model based on the situation awareness theory, and proposes a wind power based on situation awareness. Access to the frequency control method of the power transmission system. By summarizing the current status and development laws of power-frequency characteristics, a nonlinear mathematical model is constructed to predict the frequency response in the finite time domain. According to the prediction results, the FCC parameters were dynamically adjusted, and simulation comparison tests were carried out based on the simulation model and traditional control methods. The test results show that, compared with the traditional control method, under the situational awareness-based control method, the maximum frequency deviation of the system is reduced by about 41.6%, and the frequency callback time is reduced by about 11.6%, which can effectively increase the frequency recovery rate of the system and reduce the system. The maximum frequency deviation probability enhances system stability.
