基于MapReduce架构的就地化分布式母线保护研究

Research on outdoor installation distributed busbar protection based on MapReduce architecture

为了解决目前母线保护装置就地安放时支持间隔少和部分保护性能差的现状,提出在HSR环网分布式母线保护的基础上,引入基于MapReduce架构的分布式设计方法。将保护子机分为调度节点和任务节点,对母线保护的差动保护模块根据子机的个数分配于不同的子机计算并进行合并,而对于各子机相关的后备保护则分配于对应子机和负责备用计算子机完成,实现母线保护的分布式计算和逻辑判断,并经过"动作三取二"逻辑出口跳闸。经过RTDS动模试验验证,此设计方案可靠性高,提高了保护装置的可用资源和性能。

In order to solve the less bay number support and poor performance of the outdoor installation busbar protection, a distributed design method based on MapReduce architecture is introduced, based on HSR ring network distributed busbar protection. The protection sub-machine is divided into the scheduling node and the task node, and the differential protection module of busbar protection is allocated some nodes to compute and merge according to the number of sub-machine, then the backup protection related to each sub-machine is assigned to the corresponding sub-machine and some redundant computing sub-machines, this design completes the busbar protection distributed computation and logical judgement, and the protection trip uses the ＂action three take two＂ logic. Through RTDS dynamic test, this design is proved high reliability and improves the available resources and performance of the busbar protection.
