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

优秀论文配套源码。分布式电源的接入使得配电系统从放射状无源网络变为分布有中小型电源的有源网络。带来了使单向流动的电流方向具有了不确定性等等问题，使得配电系统的控制和管理变得更加复杂。但同时，分布式电源又具有提高电网可靠性，绿色节能，等等优点，所以为更好的利用分布式电源为人类造福，我们必须对其进行研究与分析。
本文采取通过利用仿真软件Matlab编写计算潮流程序模拟分布式电源接入配电网的模型进行潮流计算的方法对分布式电源的稳态影响进行探索与分析。
选取了34节点的配电网网络模型，通过对单个以及多个分布式电源的接入位置以及容量的不同情况对34节点配电网的网损以及节点电压状况进行了分析。
(The distributed generation access to distribution system makes passive radial distribution network to active medium-sized power distribution network. It brings uncertainty to one-way direction power flow, etc., and it makes the control and management of the distribution system more complicated. Otherwise, it can bring a lot of benefits, such as more reliable, and it is green power. The distributed generation should be better known , so we can benefits more.
So the program called Matlab was used to compile a program to solve the power flow problem. By this program, we can text which factor can influence the distributed generation’s access to the distribution system.
The IEEE 34 Node model was chosen to be discussed how different factors can influence the power quality. This article analyzes distributed generation’s influence to the distribution system of energy lost and voltage level.
