In the intelligent-going reconstruction process of conventional substations

work on intelligent bus-bar protection is one of the difficulties. The existing intelligent-going reconstruction scheme for bus-bar protection lacks high generality. Because of the extension and application of smart substation

an efficient generic intelligent-going reconstruction scheme for busbar protections is badly needed. On the basis of multi-bay generic interface conversion device and configuration mapping method

this paper proposes a more optimized intelligent-going reconstruction scheme for bus-bar protections in conventional substations to solve the coexistence of conventional bay device and digital bay device during reconstruction. By using the configuration mapping method

the substation configuration description(SCD)file needs not be modified during digital reconstruction

reducing the reconstruction workload.
