Abstract

The invention discloses a geomagnetic storm detection and early warning system for protecting the safe running of a power grid. The geomagnetic storm detection and early warning system for protecting the safe running of the power grid comprises a current sensor, a current signal regulating module, a data acquisition card, a computer, a driving unit, an alarm device, a protecting device and a display and storage module. The geomagnetic storm detection and early warning system for protecting the safe running of the power grid has the advantages that: 1, geomagnetic induced current can be precisely measured; 2, hardware and software are combined, so that the operation is convenient and simple; and 3, through the high-speed data computing and data processing capability of the computer, the safety of the power grid and the data storage capability can be greatly improved.

Description

(1) Technical field: [0001] The invention belongs to the technical field of safe operation of power systems, in particular to a geomagnetic storm detection and early warning system for protecting the safe operation of a power grid. (two) background technology: [0002] When the sun is active, especially during the sunspot maximum period, the sun will radiate X-rays, ultraviolet rays, visible light and high-energy proton and electron beams. The electric current formed by the charged particles (protons, electrons) impacts the earth's magnetic field, and a geomagnetic storm occurs. Magnetic storms will induce a geomagnetically induced current on the neutral wire of the grounded transformer in the power system. When this current flows into the power grid, it will pose a threat to the safe operation of the power system. At present, there are few studies on the impact of magnetic storms on power systems in my country. Especially with the increase of my over-voltage transmission ...
