为了进一步提高双功率发电机参与电力系统的频率调整的能力，使他们能够同时

In order to further improve the ability of dual-power generators to participate in the frequency adjustment of the power system, so that they can participate in the primary frequency and secondary frequency setting of the electrical system at the same time, through synchronous frequency analysis. For generators participating in the secondary frequency modulation process, a dual-power generator additional step angle controller is designed, which can simulate the synchronous generator process of the characteristic power frequency curve, and can actively respond to the automatic power generation control signal participating in the secondary frequency modulation. The power control coefficient is automatically allocated according to the state of the wind farm and the synchronization generator of the system. The results show that this control strategy can enable the wind farm to participate in the primary and secondary frequency modulation of the power system more effectively, and improve the frequency modulation capability of the entire system.

In order to further improve the ability of dual-power generators to participate in frequency adjustment of power systems, they can participate in both the main frequency and secondary frequency settings of electrical systems through simultaneous frequency analysis. The generator involved in the secondary FM process designs a dual-power generator with an additional step angle controller that simulates the synchronization generator process that performs the characteristic power frequency curve and actively responds to the automatic power generation control signal involved in the secondary frequency modulation. The power control coefficient coordinates the automatic distribution with the synchronous generator of the system according to the state of the wind farm. The results show that the control strategy can make the wind farm participate in the power system's one-time FM and the second-time FM more effectively, and improve the FM capability of the whole system.
