水轮发电机组故障监测系统互感器选型优化设计

Optimization Design of the Transformer Selection for Fault Monitoring System of Hydro-turbine Generator Units

建设和运维成本低以及安全可靠是水电站水轮发电机组追求的目标。基于APH方法设计和优化水轮发电机组故障监测系统方案,通过设置监测系统多个属性,建立方案中互感器选择的层次分析因素矩阵模型,对系统中互感器的功效做出全面的综合评价,选择最优的互感器,并以此量化得到最优的机组故障监测系统方案。

Low construction,operation and maintenance costs,as well as safety and reliability of hydro-turbine generator units,are the important goals pursued by hydropower stations.Based on the analytical hierarchy process(AHP)method,a fault monitoring system for hydro-turbine generator units is designed and optimized.By setting multiple attributes of the monitoring system,an AHP factor matrix model for the transformer selection is established.A comprehensive evaluation of the effectiveness of the transformers in the system is then carried out and the optimal transformer types are selected.Thus,an optimal scheme for the unit fault monitoring system is obtained with quantified indicators.
