The Control and Simulation of ADRC-based for VSC-HVDC System [PDF]

Proceedings of the 2015 International Conference on Advances in Mechanical Engineering and Industrial Informatics, 2015
The high voltage direct current transmission based on voltage source (VSC HVDC) technology has been widely used in transmission areas. Aimed at the problem of the low Steadystate accuracy and weak anti-interference ability for the traditional PI control, a control strategy based on ADRC was proposed.
