Theoretical line loss online accurate calculation system of actually-measured data

Abstract

The invention discloses the theoretical line loss online accurate calculation system of actually-measured data. The system comprises the following processes of 1) a preparation process before an actual test; 2) a data actual measurement process; 3) a data arrangement process; 4) a line loss calculating process; and 5) result analysis. The system has great advantages in data graph acquisition, datacalculation method diversity, calculation result analysis, and calculation result report and summary report output. Aiming at a calculation result, line loss analysis and a loss-reduction auxiliary decision can be performed, and the reactive power optimization of a transmission and distribution network, transformer-substation economic operation, network loss sharing, harmonic negative sequence analysis, low-voltage area power supply position optimization, high energy consumption distribution transform replacement, voltage optimization suggesting, lead replacement, three-phase unbalance adjustment and other loss-reduction auxiliary decision functions are realized. According to the demand of a client, different calculation result reports are selected, and according to load actual measurement and the format of a line loss theory calculation analysis report template, the report is generated, which is convenient for filling in the report in a later period; and the accuracy of line loss calculating and work efficiency are effectively increased.

Description

technical field [0001] The invention designs the field of power grid line loss calculation, and is specifically an online precise calculation system for theoretical line loss of measured data. Background technique [0002] With the continuous development and progress of society, especially the rapid development of science and technology, people have moved from slash-and-burn farming to today's electrification and information age. In the process of rapid development of modern society, electric energy provides the foundation for the development of most industries. Strong kinetic energy support, and social development has an increasing demand and dependence on electric energy. However, due to the dense power grid, when the electric energy is transmitted to the terminal through the wires, there will be electric energy loss due to many reasons. When all the small losses are accumulated together, it is also a huge loss figure. [0003] The theoretical line loss calculation work i...
