Rural Power Grid Line Loss Calculation And Analysis Of Loss Reduction Measures

Management line loss is an important element in cost management of power supply enterprise. With the development of the market economy, it requests the power supply enterprise to take the economic efficiency as a center, speed up the transformation of urban and rural distribution network., further to reduce and control the line loss rate. In order to strengthen management line loss, it must require more precise calculation of the theoretical line loss and the distribution network to provide the reference for the safe and economic operation of the distribution network. Theoretically, the line loss characteristic is that the electric energy disappears in the around space of the network components in the form of heat energy and corona discharge. Therefore the line loss of power network is a natural phenomena and an inevitable part of line loss power. There is still avoidable unreasonable part in line loss power, so the size of line loss in each power network is different. It can be reduced to a reasonable value range in appropriate measures.This thesis is divided into three main parts. The first part, based on the study of calculation principles and methods of the theory of line loss in high-voltage distribution network, also combined the actual parameters of the network structure and operating parameters, deals with the calculation of theoretical line loss of power network. The second part, integrated with theoretical calculation principles and results, proposes the measures to reduce the technical line loss in rural power network in the aspects of adjusting the distribution of power network, optimizing the structure of power network and improving the operational methods. That is the part of theory value of reducing line loss. The last part studies a new reactive compensation device on pole, combined the voltage characteristic and the measures to reduce loss of power network in rural area to achieve the reactive power comprehensive compensation. The research methods is mainly carrying out theoretical calculation in light of actual power network, studying based on the theoretical calculation and proposing the suitable measures to reduce loss of power network in rural area.The structure of distribution network in county level is complex.
