摘要: With a rising amount of high voltage dc projects to be overlaid the transmission grid, thorough understanding utilized equipment regarding its impact on system stability is required. To cover this need, passivity-based assessment represents one promising option investigate damping behavior converter over wide frequency range. Assuming acts in passive manner at certain frequency, it adds overall and contributes mitigate un-wanted interactions e.g. related pre-existing ac grid resonances. By means an encompassing analysis input-admittance, relevant sensitivities are classified terms their passivity characteristics ranges. Moreover, feasible delay design criteria determined.
