| Abstract: | To study the load optimal regulative characteristics of doubly fed hydrogenerator system, the optimal regulative characteristics of doubly fed hydrogenerator and conventional synchronous generator are compared under the same operation condition in terms of practical case. Using an improved back propagation (BP) neural network algorithm namely Levenberg- Marquardt BP algorithm, the mathematical model for optimal regulative characteristic of hydroturbine is built up and the calculation results of this model are compared with those of other models. The calculation results prove that the model for load optimal regulative characteristic of doubly fed hydrogenerator based on improved BP neural network algorithm is effective. |
