通用接口转换装置在常规站母线保护智能化改造中的应用

Application of Generic Interface Conversion Device in Intelligent-going Reconstruction for Bus-bar Protections in Conventional Substations

在常规变电站的智能化改造过程中,母线保护的智能化改造工作是难点之一,现有的母线保护智能化改造方案通用性不高,改造工作量大。随着智能变电站的广泛推广应用,亟须寻找一种通用高效的智能化母线保护改造方案。文中依托于多间隔通用接口转换装置及配置映射方法,提出了一种更优化的常规站母线保护智能化改造方案,解决了智能化改造过程中常规间隔设备与智能化间隔设备同时接入智能化母线保护的问题,采用配置映射的方法使改造全程无需修改变电站配置描述文件,减少了改造工作量。

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.
