A detailed methodology and consistent results related to the evaluation and validation of the Multiple Infeed Short Circuit Ratio as an index of the system strength in a particular point for Double Infeed HVDC systems are presented in this thesis. The evaluation will be carried out by comparing the critical MESCR with respect to the critical Short Circuit Ratio for a Single Infeed HVDC system. These critical values represent the weakest AC-network that connected to the inverter is able to keep the system stability after a disturbance. These stability limits are obtained by studying the risk of voltage instability.
The results presented in this work conclude that the validation is positive and the stability limit can be set in 1.3.
