Abstract

This paper proposes a novel method of rapid calculation of the peak amplitude of the power surge at one of the AC side in the asynchronous grid connected with a HVDC network due to other AC side fault. The proposed approach is based on simple linear modeling of a HVDC network connecting two asynchronous AC grids. The proposed approach helps in the rapid estimation of peak value of power surge at the AC grid and hence quickly initiating protection measures. The proposed method has been implemented on standard PSCAD HVDC system and results have been compared with calculated values which verify the aforementioned approach.
