A Survey Of Decision Support System For Transformer Equipment Condition-based Maintenance

The present scheduled maintenance has severe disadvantages.As the reform of power industry goes and the improvement and popularization of the technology such as fault diagnosis and on-line inspection achieves,the introduction of condition-based maintenance technology of transformer equipments into power system becomes more and more significant. Because of the complexity of CBM and the advantage of decision support system,it is necessary of inducting DSS to CBM.The article presents a advanced feasible and perfect scheme of condition-based maintenance system based on the research of condition-based maintenance technology, decision support technology,data security technology of MIS and so on.The fulfillment of the scheme and the run of the system in two test transformer substations show that the system is intelligent,the decision-making results offered by the CBMS is reasonable and credible and it improves the maintenance efficiency of the transformer equipments.
