配电自动化系统数据库的实时处理方案

A Real-Time Database Scheme for Distribution Automation System

基于配电自动化系统的实时性需求,提出系统数据库的实时工作流程,主要研究分级处理的硬件构造、多线程机制及内存资源优化等问题,重点解决文件关联、内存资源回收等关键技术,并采用C++实现。基于等价实验方法,结果表明,数据库的延迟小,实时性好,方案可行。

According to real-time requirement of distribution automation systems, this paper brings forward the real-time working process of database and discusses some new schemes, including hardware constitution based on hierarchy treatment, the multithreading mechanism and optimization for the EMS memory resource. The paper also resolves some key technologies, such as file relevancy and recovery of the EMS memory resource, which are all realized by C＋＋. Through the equivalent experimental method, the results show that the database possesses less delay and satisfying real-time and the scheme is feasible.
