Power grid overcurrent protection method and system, storage medium and electronic equipment

Abstract

The invention discloses a power grid overcurrent protection method and system, a storage medium and electronic equipment. The method comprises the following steps: obtaining a current signal collected by a current collector through a first main controller, wherein the current signal is a current signal of a power grid main loop collected by the current collector through a fault current limiter; and enabling the first main controller to determine whether the power grid main loop has a fault according to the current signal, and if it is determined that the power grid main loop has the fault, sending a fault signal to the first switch controller, and enabling the first switch controller to generate a control command corresponding to the fault signal and aiming at the power grid main loop according to the fault signal. Therefore, the current of the main loop of the power grid can be detected and identified, so that whether the main loop of the power grid breaks down or not is determined. Moreover, after the fault of the power grid main loop is determined, the control command for the power grid main loop can be generated, the switch of the power grid main loop can be turned off in time, and the response speed of the system is high.

Description

technical field [0001] The invention relates to the field of power grids, in particular to a power grid overcurrent protection method, system, storage medium and electronic equipment. Background technique [0002] With the continuous expansion of the grid scale, the short-circuit current exceeding the breaking capacity of the existing circuit breaker has become a serious threat to the safety of the power grid in the heavy load center. The fault current limiter is an important power equipment to solve the short-circuit current exceeding the standard and limit the short-circuit current to the level that the existing circuit breaker can normally break. However, the fault current limiter needs to rely on a reliable control system to exert its capabilities. [0003] At present, the closest existing technologies are high-voltage switch on-line monitoring system, high-voltage switch control and detection system. The architecture of this type of system is mostly for individual monit...
