Abstract

The invention provides a line fault monitoring method, device, a computer readable storage medium and device. The method comprises the steps of obtaining A-phase current, C-phase current, active power, and bus voltage of a line; calculating B-phase current of the line based on the active power and the bus voltage of the line; determining whether the line has fault or not based on the A-phase current, the B-phase current, the C-phase current of the line; if the line has a fault, the fault information will be forwarded to workers. The invention is advantageous in that fault can be found by workers in first time, and the fault can be processed in time; work intensity for workers can be greatly reduced, long-time running of devices with faults can be prevented, and safe running of device and safe usage of electricity for users can be ensured.

Description

technical field [0001] The invention belongs to the field of electric power technology, and more specifically relates to a line fault monitoring method, device, computer-readable storage medium and equipment. Background technique [0002] Three-phase alternating current is a form of electric energy transmission and is widely used in industry, agriculture, and daily life. Therefore, the safe and stable operation of three-phase power lines has a great impact on people's lives, industry, and agricultural production. [0003] In the prior art, due to the cost and difficulty of construction, the high-voltage lines of the power grid are mostly steel-cored aluminum stranded wire overhead lines, and the overhead lines are easily affected by external factors such as weather and man-made, resulting in disconnection and phase loss faults. However, it is often difficult for the on-duty controller to discover the phase loss and disconnection faults in the line at the first time, which ma...
