Introduction about Anti Misoperation Software of the Remote Control Soft-clamp for the Smart Substation

Combined with the actual situation that the skill level of relay protection maintenance personnel in new energy stations is insufficient, this paper analyzes the misoperation impact of the soft-clamp on the security and stability of the power grid, and puts forward a detailed method to judge the misoperation prevention of the soft-clamp. A logic judgment module is added to the remote control operation of soft-clamp, which makes full use of the operation state information of smart substation, and designs a reasonable and effective misoperation locking criterion to monitor the remote control operation of the soft-clamp in real time. It improves the reliability of the remote control operation of soft-clamp and expands the data application of smart substation based on state information. Finally, combined with the actual smart substation, the effectiveness and practicability of the developed misoperation prevention software for of the soft-clamp are verified.
