Abstract:

At present the methods for measuring high voltage cable temperature can only measure current temperature, lag behind control and not identify  it in advance. After research on the traditional methods to measuring cable temperature, a new method using neural network controller to measuring high voltage cable temperature was proposed. On the basis of three conventional controllers, three kinds of controllers using a neural network were designed. They are the neural self-adjustment controller, the neural PID controller and the neural adaptive controller. All themethods were simulated by MATLAB. According to  the simulation results, the neural PID controller was proved to be  the best controller to apply to high voltage cable measuring temperature system, which was  verified by the power supply system in Xinjiang with  good results.
