A transmission channel model for transient stability assessment of power grid dispatching system automation communication network is constructed. The anti-interference design of power grid dispatching system automation communication is carried out by using information fusion and power grid output gain estimation model. The dynamic migration state characteristic quantity of power grid dispatching system automation communication symbol is extracted, and the random channel spread spectrum gain scheduling method is adopted. The balance control of the transient stability assessment of the communication network of the power grid dispatching system automation is carried out, the optimization of the transient stability assessment of the communication network of the power grid dispatching system automation is realized, and the anti-interference and security of the transient stability assessment of the communication network are improved. The simulation results show that the channel balance and output anti-interference of the proposed method are good, and the accuracy and steady-state dispatching ability of the automatic communication network of power grid dispatching system are improved.
