Quantitative Reliability Analysis of HVDC Transmission Systems Part I. Spare Valve Assesment in Mercury Arc Bridge Configurations

The high voltage direct current link is normally an integral part of the overall composite system. The design of any subsystem should be such that it does not materially effect the reliability of the overall system. The application of probability techniques can play an important role in the determination of subsystem and overall system adequacy. Numerous papers have been published on the application of probability methods to the evaluation of generating, transmission and distribution system reliability evaluation. The probability method used in the analysis of the dc subsystem should be compatible with that available for the ac system thus leading to overall composite system reliability evaluation.
