Feasibility of application of artificial neural network (ANN) controllers for HVDC systems control

Up till now conventional controls are used with either two terminals links or multi-terminal HVDC systems. In this study the recent artificial neural network (ANN) control is applied to the HVDC system control. Suggested novel (ANN) control is used in creating a new supplementary control signal added to the input of the conventional controller in a special manner. The control is applied to the rectifier station. Transient time simulations of the nonlinear system performance after certain disturbances have proved the effectiveness of such (ANN) controls, which act very fast to follow transient system conditions and to restore its stability subsequent to severe disturbances through fast oscillation damping. Numerical integration is used to solve the nonlinear system equations.
