摘　　要：针对已有发电厂继电保护整定系统运行时需要大量人工操作及难以灵活管理数据的问题,提出了基于一体化数据结构的整定系统.首先分析了发电厂继电保护整定计算过程业务功能所涉及的数据并对其进行板块划分,通过数据间的关联关系建立了整定计算一体化数据结构.然后利用SQL数据库定义了数据结构的详细内容,通过数据表之间特定的编码建立了实体对应关系.最后将一体化数据结构应用到图形化建模、故障计算以及整定计算板块中,实现了自动整定计算.经某发电厂应用表明,基于该数据结构开发的整定系统在数据灵活管理、减少人工操作量以及系统性能提升方面效果显著.Aiming at the problem that the existing power plant relay protection setting system needs a lot of manual operation and difficult to manage data flexibly,a tuning system based on integrated data structure is proposed.Firstly,the data involved in the business function of the relay protection setting calculation process of power plant are analyzed and divided into sections.The data structure is established through the relationship between data.Then use the SQL database to define the details of the data structure,and establish the entity correspondence through the specific coding between the data tables.By applying the integrated data structure to the graphical modeling,fault calculation and tuning calculations,the entire tuning calculation process is fully automated.A case study shows that the tuning system developed based on the data structure has significant effects in data flexible management,reduction of manual operations and system performance improvement.
