Problems solved by technology

[0003] In the existing technology, various methods can be used to reduce the line loss rate, such as reducing the radius of the power supply, improving the load power factor, changing the diameter of the transmission line, etc.; electric power workers need to constantly check the location and cause of high line loss, And take measures to reduce the line loss of the power network based on historical experience; however, due to the large laying area of ​​the power network, the large amount of power data, and the heavy investigation tasks of the staff, the final determination of the cause of the high line loss is inaccurate, and the corresponding measures taken The effect is also very limited
[0004] Aiming at the above-mentioned problems that the analysis workload of power line loss is heavy and the effect of reducing line loss is poor, no effective solution has been proposed so far.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a power line loss analysis method, device and system. Background technique [0002] Electric energy is transmitted through step-up transformers at all levels, transmission lines at all levels, and step-down transformers at all levels. The conversion of electric energy and magnetic energy of transformers at all levels, energy loss in the resistance of transmission lines, and poor management of power supply enterprises will all cause loss of electric energy. In the process of transmitting and distributing electric energy, the power loss, electric energy loss and other losses generated by various components in the power network are collectively referred to as line loss, or line loss for short. [0003] In the existing technology, various methods can be used to reduce the line loss rate, such as reducing the radius of the power supply, improving the load power factor, changi...
