摘要
对地县进行继电保护整定计算时,也必须要考虑到计算应用的时效性。为了实现快速的继电保护整定计算,采用并行计算技术。首先对硬件部署做了总体介绍,为并行计算的实现提供可能性;然后采用基于Hadoop的分布式并行计算,介绍了Hadoop的软件框架及任务分解;最后以浙江湖州德清县调整定计算的具体实例来说明并行计算的实现方法。结果表明:该方案可适应电网发展对继电保护提出的更高要求,减少计算时间。
Timeliness of computing applications should be also taken into consideration when relay setting calculation is conducted for county-level power companies. To achieve rapid relay setting calculation Parallel computing technology is used. First,this paper gives a general introduction to the hardware deployed to deliver possibility of realization for the parallel computing, and then based on Hadoop distributed parallel computing,it introduces Hadoop software framework and task decomposition. Finally,taking the relay setting calculation in Deqing County as an actual example,the paper specifies the implementation method of the parallel computing. The result shows that the proposed method meets the higher requirements for replay protection in the grid development and reduces the calculation time.
