摘要
随着电力信息化的发展,各种在线的生产、营销系统的性能已经成为电力系统发展的瓶颈。引入电力系统分析计算从理论上解决了信息系统实时快速分析的难题,但在实际的系统应用中,多核硬件的处理能力并没有完全发挥出来,已渐渐成为整个系统的性能瓶颈。文章结合电力系统软件的特点,采用了基于PMU的多核检测方法,设计并实现了多核环境下电力信息系统性能检测及调优系统软件,分析和检测在线生产、营销系统的瓶颈,找出影响系统性能的主要原因,并生成相应的调优报告,有针对性地提出了系统调整方案。
With the development of electric information technology, the performance of various online production and marketing systems has been a bottleneck in the development of power systems. The introduction of power system analysis and calculation will be helpful to solve the issue of real-time analysis of information systems theoretically. However, the processing power of multi-core hardware does not fulfill the practical application of systems, and has gradually become another performance bottleneck of the whole system. According to the characteristics of power system software, this paper designs and implements a system software for performance detection and optimization of power information systems under the multi-core environment through the PMU-based multicore detection methods. The system can not only analyze and detect performance bottleneck of the on-line production and marketing system, but also determine their root causes and make the corresponding optimization report to tune the system.
