ABSTRACT: A method based on fuzzy comprehensive evaluation to
optimize the maintenance strategy of HVDC transmission system is proposed to
provide quantitative reference for the maintenance arrangements. Firstly, a
system based on fuzzy comprehensive evaluation, is established to fuzzy the
index results of power system adequacy evaluation, so as to analysis the degree
of risk in the operation of power system and the effect brought by the
maintenance of HVDC. Then, the proposal on the maintenance of HVDC can be
formed through the quantization and evaluation summary of the fuzzy results.
The equivalent network of the China Southern Power Grid in 2011 ,which
respectively operates in the circumstances of peak load, general load and
low load, demonstrates the HVDC transmission systems in different operation
modes have corresponding Overhaul timing .The result shows that the method
proposed is valid and in accordance with engineering practice.
