Abstract :
The design, construction and test of a new hybrid control for static compensators (STATCOM) is presented. It uses a digitally controlled oscillator (DCO) to synchronize the STATCOM with an AC system that may exhibit frequency variations. The control also schedules the firing of the converter valves in order to achieve the reactive power compensation level required in the connection bus of the AC system. The design of the control system was carried out with the help of Simulink® and Matlab®, and was implemented in the laboratory by means of a PIC16F877 microcontroller. Simulated and experimental results for a prototype STATCOM are presented in the paper.
