Abstract

The invention discloses a secure automatic device constant value file modification method and system, and the method is applied to a network comprising scheduling equipment and a plurality of secure automatic devices, and comprises the steps: the scheduling equipment issues a constant value file used for modifying a secure automatic device constant value to a target secure automatic device; by checking the selected fixed value file and the device number of the target security automatic device, the wrong sending of the selected fixed value file is avoided, and the risk of manual misoperation in the process of modifying the fixed value of the device by issuing the fixed value file is reduced; and the correctness and effectiveness of the action of the safety automatic device after the power grid breaks down are improved.

Description

technical field [0001] The invention relates to the technical field of electric power system safety, in particular to a method and system for modifying a fixed value of a safety automatic device as a file. Background technique [0002] Power system safety automatic devices include safety and stability control devices, low-frequency and low-voltage load shedding devices, out-of-step disassembly devices, and backup power automatic input devices. As key equipment to ensure the safe and stable operation of the power grid, they are widely used in the power grid. [0003] When the power grid fails, the safety automatic device quickly matches the internal strategy setting value of the device according to the real-time operating conditions of the power grid, and implements control measures such as cutting machines and loads. If the setting value of the device is not set correctly, it will affect the correctness and effectiveness of the action of the device when the power grid fails,...
