摘要：
In the condition of relatively weak system inertia,the quick primary frequency regulation technique is particularly important to maintain the system stability. Based on the primary frequency regulation of traditional power plant,the concept of quick primary frequency regulation is put forward by using the characteristic that the propagation speed of frequency disturbance signal in communication network is faster than that in power grid. In order to improve the system stability,a primary frequency regulation control is added in the traditional inertial action area. To realize quick primary frequency regulation,a quick primary frequency regulation method of the whole network with event trigger control is proposed,and a single machine quick primary frequency modulation control strategy after the event trigger is given. The two-area four-machine system model is built for comparative simulation,the results show that the proposed method can speed up the frequency stability recovery and reduce the frequency fluctuation amplitude. © 2021, Electric Power Automation Equipment Press.
