Evaluation of unattended electricity substation maintainability based on grey relation
Qian Xianyi · 2012
The construction principles of the fuzzy evaluation model are researched.The fuzzy comprehensive evaluation theory model is established based on the fuzzy mapping and grey relation theory.A unattended substation maintainability evaluation gray relation modeling and calculation method are proposed.A unattended substation of 220 kV maintainability evaluation is given as an example.The results show that by using the two-layered model,the computational complexity of multi-factor assessment can be significantly reduced and the objective assessment can be efficiently implemented.
