英文摘要：

Currently, the maintenance technology of gas turbine is monopolized by foreign companies, and the life cycle maintenance cost of power generation equipments is very expensive （17.8 times of the pur- chase cost）. To reduce the maintenance cost for gas turbine,this paper designed a novel gas turbine mainte- nance decision system and introduced a calculation method for predicting the life cycle of relevant parts of the gas turbine. Moreover, the maintenance decision-making key parameters were proposed. On this basis, the heavy-duty gas turbine maintenance decision-making model was established. Then, the structure and implementation framework of background calculation server and WEB server of the maintenance decision- making system was designed. Finally,based on B/S structure model,the preventative maintenance decision system for gas turbine was developed. The field application verified this system can provide more efficient decision for the gas turbine＇s maintenance decision,and the system operated stably.
