The System Development Of Zhongyuan Oilfield Distribution Network Line Loss Calculation

Distribution line loss rate is a comprehensive economic and technical indicators. It can reflect the level of oil companies planning the design, production technology, business management level. Line loss rate directly affects the economic efficiency of enterprises.Firstly, this reality, describes the power of the network structure of Zhongyuan Oilfield, operation, equipment status, describes the Zhongyuan Oil Field Status Line Loss Management, and the current line loss calculation problems were analyzed; describes the loss of distribution system computational algorithms, especially for the rms current, average current law, the equivalent resistance law for a more in-depth analysis; According to the established power grids, to build the distribution network topology, propose the node and branch numbering scheme , Establish loss calculation mathematical model.Secondly,after the theoretical analysis, the programming language Visual Basic 6.0 and Access database technology as the basis, describes the design and development of this software and its network of distribution points for halfback a change in the actual line of network loss calculation,Finally,in the laboratory condition, developed a set of zhongyuan oilfield 35 (6) kV power loss calculation software platform, and of the distribution of zhongyuan oilfield defended a variable 35kv power distribution lines were tested. According to the test data calculated to line loss, obtained the line loss data. The results verify the thesis net loss calculation method is correct. This platform operation conveniently, suitable for different operating personnel, can also convenient establish one or more data tables, to safeguard the economic operation of the power grid provide the technical basis.
