Abstract: Frequency control has always been one of the concerns in the operation of interconnected power grid. Considering new demand of frequency control in UHV transmission system, combined with the five level dispatching management model of "Unified Dispatch, Hierarchical Management" in China power grid, the control thought that frequency control in China should be divided according to the dimensions of disturbance severity is proposed. And the performance evaluation method of disturbance control suitable to integral frequency control under high-power loss fault as well as the three level scheduling schemes for state grid, regional grid and provincial grid are designed on the basis of in-depth analysis of North American reliability standard set. The simulation results show that the performance evaluation method for frequency control of interconnected power grid concerning all kinds of power disturbances has better frequency control effect than the disturbance control method of North American. The new method can improve anti-disturbance ability effectively and is beneficial to safe and stable operation.

Key words: UHV transmission system, frequency control, disturbance control, operating state
