能量管理系统中实时数据和历史数据处理

Research on the Processing of Real-Time Data and History Data in EMS

研究SCADA/EMS系统中的实时数据处理,设计并实现了一种基于多任务的实时数据处理方法,讨论了多任务数据处理中的数据共享和任务协同问题。同时研究了SCADA/EMS系统中的历史数据处理、历史点的关系模式,提出基于动态定制的历史数据采样方法和基于动态分配存储位置的历史数据存储方法。实际应用表明,这些方法提高了实时数据和历史数据处理的效率和性能,满足了大型SCADA/EMS系统的要求。

A deep research on the need of real-time data operating and the multi-tasked operation in the SCADA/EMS system was done in this paper.This paper puts forward the method of using the circulatory queue to share the data among the multi-tasks to avoid dead-lock,and also using the event-driver to harmonize multi-tasks perfor-mance to improve the system efficiency.A research on the relation model in history data operating was also done in this paper,and a new method of storing history data was discussed.Practical applications show that the meth-ods have improved the efficiency and met the need for large-scale SCADA/EMS system.
