Abstract
Method for determining parameter of a passive impedance adapter applicable to VSC-HVDC, including: S. obtaining VSC-HVDC impedance and VSC-HVDC impedance curve X(f) based on VSC-HVDC impedance; S. estimating upper limit value of the main capacitor in the passive impedance adapter; S. calculating adapter parameter curve X(f); S. determining value of the main capacitor and varying value of the main resistor until min[X(f)−X(f)] is maximized; determining whether min[X(f)−X(f)]>k holds; S. If min[X(f)−X(f)]>k does not hold, increasing the value of the main capacitor and performing steps S-Suntil min[X(f)−X(f)]>k holds when the value of the main capacitor is within the range of the value of the main capacitor, storing the parameters in an available parameter set; S. reducing the value of the main capacitor, and storing the parameters when min[X(f)−X(f)]>k holds in the available parameter set; S. selecting the available parameters from the available parameter set.
