The construction of ultra-high voltage grid and the input of large generating units make the out-of-step protection become increasingly important. Traditional out-of-step protection device can only judge from local perspective, no consideration to the global situation. In order to solve this problem, a coordination control method of generator out-of-step protection based on WAMS transient stability prediction is proposed, the coordination between grid side out-of-step protection and the generator out-of-step protection is achieved. Using the self-memory trajectory to predict the stability of grid, calculate excess energy of system based on EEAC theory, and utilize convexity-concavity of phase diagram method which is not affected by the change of network structure to judge the stability of system. Utilize double forecast strategy to improve the stability of the system further. |
