The invention provides an automatic teed line parameter calculating method and a device. The automatic teed line parameter calculating method and the device are used for solving the problem that efficiency and accuracy rate are poor in calculation of parameters of a teed line in the prior art. The automatic teed line parameter calculating method includes the following steps. A starting point and a teed joint of a main line of a to-be-calculated line are obtained. Corresponding models and length of all line segments between the main line starting point to the teed joint are obtained from a production management system (PMS). Characteristic parameters of power grids corresponding to the models are confirmed. Based on the characteristic parameters of the power grids and the length, line parameters between the starting point of the main line and the teed line are calculated out and output. With the automatic teed line parameter calculating method and the device, efficiency and accuracy rate in calculating out teed line parameters are benefited and improved.
Description
technical field [0001] The invention relates to a method and a device for automatically calculating parameters of a T-connection line. Background technique [0002] With the development of social economy and the improvement of people's living standards, the demand for electricity is increasing, which makes the scale of the power grid continue to expand. However, at the same time, due to the increasing shortage of land resources in the urban area, the area of the transmission corridor is limited. T-connecting lines on the line can not only save wires, but more importantly, it can save priority land resources. Therefore, the erection method of T-connecting lines in urban power grids has been more and more widely used. According to the current power system dispatching department's naming convention for line equipment, the original T-connected line is called the main line, and the later erected line is defined as the branch line of the main line from the T-connection position ...
