Analysis And Study On The Line Losses Of Distribution Network

Currently, the research on statistical line losses is less than that on theoretical line losses in the analysis and study on distribution network line losses. The power bureau often uses the result of statistical line losses, though the assessing index is the result of theoretical line losses. However, it is necessary to take more emphasis on the research of statistical line losses because of the big difference between theoretical line losses and statistical line losses and the large-scale fluctuation of statistical line losses.This paper mainly studied the influence of asynchronous problem on statistical line losses between power supply and consumption, provided three solving methods, proportional coefficient method of power supply, curvilinear imitation method of power consumption and curvilinear interposition method of power consumption, and got the real synchronous loss rates of distribution network for the first time. This research has some degree of theoretical meaning and promotion values, because the asynchronous problem between power supply and consumption is pervasive all over the country.Meanwhile, this paper researched theoretical line losses, compared per-line results between theoretical and statistical line losses, and elementarily discussed the reason of difference. The author also supplied his own view points on the analysis and management of loss rates based on actual conditions. This paper also studied forecasting errors and forecasting methods, which will do good to load forecasting.
