Research on Economical Operation of Transformer Considering Reliability

In the process of determining and investigating the reasonable operation mode of transformer, how to consider reliability and economic operation of transformer is a very important and necessary work. This dissertation chiefly studies the topic of accounting reliability and economic operation of transformer. Economy and reliability are the most two important index of Power System, but also contradictory to each other. To solve the contradiction, in this paper, reliability index will be expressed with the customer interruption costs, which is the way to change reliability index into economic indicators. And also, this paper did the basic research of economic operating modes and reliability optimization. It finds popular conclusion on the basis of question simplification. This is useful for further research on considering reliability and economic operation of transformer.
