DSP-based Direct Power Control of a VSC with Voltage Angle Estimation
This paper presents a direct power control (DPC) method applied to a three-phase voltage source converter (VSC) connected to the grid. The influence of distorted angle information due to disturbances in the grid voltage, such as harmonics, unbalances, faults, etc., on the direct power control of the converter is taken into account through the use of an algorithm for voltage angle estimation. The control performance is compared in both cases, with and without angle estimation, as a mean of establishing an improving voltage ride-through capability of the converter in case of grid disturbances. The system has been simulated in MATLAB/Simulink and the simulation results have been validated with experimental results, obtained implementing the DPC and the angle estimation algorithm on a real-time DSP-based board (dSPACE ds1102), verifying the good performance of the proposed method
