Abstract

The voltage source converter (VSC) multi-terminal high voltage direct current (MTHVDC) is a suitable solution to connect offshore large renewable power stations. However, relevant fast and intelligent fault current location techniques are of utmost importance to improve power system stability and maintain continuity of supply. This paper proposes a hybrid travelling wave fuzzy logic based wavelet decomposition technique to identify the faulty line in a MTHVDC network, in addition to accurately determine the fault location. A fuzzy logic voter is applied to analyze non-stationary current travelling waves generated at fault location and captured by special DC current sensors to identify the faulted pole. Secondly, the captured wave of the identified pole is further decomposed by a discrete wavelet analyzer to accurately identify the fault location. A MATLAB toolbox is constructed to show the validity and adequacy of the proposed algorithm. This technique is important to MTHVDC dispatch centers especially those used with offshore wind farms.
