The invention discloses an overcurrent protection method, device, terminal equipment and a computer-readable storage medium. The method includes: determining the current error prevention line type of the power system according to the adjacent line information of the power system; judging different types Whether the current anti-mistake line below meets the remote anti-mistake condition, when the current anti-mistake line meets the remote anti-mistake condition, obtain the line operation data of the power system; judge whether the line operation data satisfies the current The preset condition corresponding to the type of anti-misoperation line, and when the line operation data meets the preset condition, an overcurrent protection action is executed. The overcurrent protection method provided by the present invention is based on different anti-misoperation line types and operating data, thereby more accurately identifying the misoperation prevention condition, avoiding unnecessary overcurrent protection actions, and contributing to the stable operation of the power system.
Description
technical field [0001] The present invention relates to the technical field of overcurrent protection, and in particular, to an overcurrent protection method, an apparatus, a terminal device and a computer-readable storage medium. Background technique [0002] In the power system, line faults or trips will cause power flow transfer, and the overcurrent protection of a certain line of conductors will act. At present, the common error prevention condition is mutation prevention, that is, as long as any interval between the same voltage level of the substation meets the mutation threshold, the error prevention condition is opened, and the overcurrent protection of the line is allowed. However, this general anti-error strategy, under special circumstances, is likely to cause the false opening of the anti-error condition, which in turn affects the normal operation of the power system. Therefore, how to provide an accurate and effective overcurrent protection method is one of the...
