Gene Atlas Relationship-based Anti-override-trip Protective Method for Distributed Smart Grids
The current prevailing anti-override-trip mechanisms for distributed smart grids are mainly target position-guided protection with limited protection range,resulting in the continuous decline of emergency response frequency.For this reason,this paper proposes a gene atlas relationship-based anti-override-trip protective method.First according to the current anti-override protection requirements,the abnormal characteristics of the power grid are identified,and multiple monitoring nodes are deployed.Then the multi-level method is adopted to break the limitation of the protection range,and the multi-level protective mechanism of the station area is formulated.Consequently the gene atlas-based anti-override pro-tection model is established,and continuous tracking and monitoring is adopted to achieve anti-override handling.The pro-posed protective method achieved emergency response frequency higher than 12 in the 3-stage test within the selected H power grid anti-override protection area.This indicates the proposed gene atlas-based method has satisfactory sensitivity,faster early warning response,and significantly improved selectivity.
