| Abstract: |
| In order to solve the problem of establishment and practical engineering application of secondary equipment operation evaluation system for smart substation, the comprehensive evaluation model of secondary equipment based on multi-parameter information fusion is introduced. The evaluation sub-items, evaluation parameters and evaluation methods are proposed to evaluate state of different types of secondary equipment. A trend assessment model is established to characteristic health status of secondary equipment by monitoring the change of steady state quantities, while a loss assessment model is established to characterize failure degree of secondary equipments. Engineering quantification index of different evaluation subitems are proposed. The secondary equipment health evaluation system is developed and has been applied in 500 kV smart substation project. |
