Problems solved by technology

Once the system fails, the voltage at the central point of the transformer will increase, which will damage the acquisition equipment. In addition, when the base station is maintained or the mobile signal is weak, it will affect the transmission of data.
[0005] Therefore, it is desired to have a method and device for collecting magnetic storm induced current of transmission lines to solve the problem that the equipment installed on the neutral point grounding bar of the transformer is vulnerable to damage in the prior art

Abstract

The invention discloses a Beidou short message-based transmission line magnetic storm induced current collection method and device. The transmission line magnetic storm induced current collection method includes the following steps that: step 1, a magnetic induction intensity sensor is installed on a transformer A-phase wire outgoing frame so as to collect a magnetic field generated by current, and the other magnetic induction intensity sensor is installed in an interference magnetic field in an environment near a substation; step 2, collected magnetic field data are sent to a preprocessing module, so that whether geomagnetic storm induced current exists in a transmission line is judged; and if the geomagnetic storm induced current exists in the transmission line, the magnetic field data are sent to an upper computer through a Beidou short message communication module, otherwise, data at a temporary storage area are cleared; and step 3, the upper computer receives the magnetic field data and processes the data so as to obtain a geomagnetic storm induction current value.

Description

technical field [0001] The invention relates to the technical field of natural disaster event monitoring in power systems, in particular to a method and device for collecting magnetic storm induced current of transmission lines based on Beidou short messages. Background technique [0002] Changes in the Earth's magnetic field caused by solar activity are called geomagnetic storms. The geomagnetic storm induced current in the power grid caused by the geomagnetic storm will threaten the safe and stable operation of the power grid. With the construction of high-voltage, large-capacity, and long-distance transmission networks in my country, more and more high-voltage long-distance transmission systems are affected by geomagnetic storm induced currents. In order to be able to monitor and record geomagnetic storm induced current data, a geomagnetic storm induced current monitoring device needs to be added to the line. [0003] Although there are online monitoring devices for geo...
