The Analysis Of Effect On Electricity Price In Transformer Under The Condition Of Harmonic

In modern electric power systems, with the increment of the non-linear loads, there is a severe pollution of the power quality because of harmonic. It's one of the main factors to affect the power quality and a severe problem of introducing competition to electricity market. Electricity price is a lever for power business in electricity market. It is important to regulate reasonable business of power and electricity price of power supply market by researching the harmonic influence on electricity price. Transformer is important electric equipment that contacts different voltage classes network in power systems, and exist in every voltage classes. We analysis the harmonic influence on transformer such as hysteresis loss, eddy current loss and winding loss, and research the effect on electric price in transformer under condition of harmonic carefully. The result of this paper has important meaning to evaluate the affection of power quality to electricity price in electricity market.Meng qingliang (Theory and New Technology of Electrical Engineering)Directed by Associate Prof. Jia xiufang...
