The Effect of Installation of Tapping Station on Interconnected AC/DC Transmission Systems

L.Devi, C.H. Saibabu, S.Sivanagaraju

The effect of tapping station on interconnected AC/DC transmission system is presented in this paper. Reliability values of AC and bipolar VSC-HVDC transmission systems are developed by using Markov modelling. The reliability indices are evaluated by DC line without tapping station and with tapping station. Reliability models of bipolar VSC-HVDC and AC systems are developed. A contingency enumeration technique with equivalent approach is used to determine the reliability indices.
