Simulation Study of Harmonic Compensation Device Based on Combination of FC-TCR and TSC for Drilling Rigs

To solve the problem of high reactive power consumption and serious harmonic pollution of the drilling rigs, a hybrid filter device based on a combination of FC-TCR and TSC was studied. Use open loop control, take reactive power as control signal, switch capacitor at voltage’s peak and use piecewise linear method to get reactor’s firing angle. Through MATLAB/SIMULINK, compensation scheme was simulated. Simulation results verified its effectiveness and validity, and it has an important guiding significance on the development of actual devices.
