电力变压器是电力系统中的主要设备之一,利用它可以把不同电压的电网联结在一起,组成复杂的电网或庞大的电力系统,并在其中发挥着重要的作用。电力变压器的可靠运行关系到整个电网的安全,如何对电力变压器的运行中的故障进行诊断,已成为电力部门急需解决的问题。目前,以油中溶解气体为特征量对变压器的故障进行分析,得到了广泛应用。
本次设计要求对电力变压器的内部故障进行广泛了解,并应用BP神经网络对变压器进行智能故障诊断软件设计,实现变压器内部故障论断。主要包括以下内容:
1、掌握用以变压器油中气体为特征量,用BP神经网络诊断变压器内部故障的方法
2、用 Visual Basic编制变压器故障诊断软件,具有以下功能:
a) 数据管理功能。包括变压器信息,色谱数据信息等
b) 故障诊断功能。包括用BP神经网络诊断变压器故障的具体实现方法,并给出故障诊断结果
c) 图形显示功能。包括对同一变压器内气体浓度变化曲线的显示等
d) 辅助功能。如帮助信息,诊断方法的介绍等
