变电站综合自动化系统的设计与研究

Disign and Research on the Comprehensive Automatic System of Transformer Substation

微机化的变电站综合自动化系统,可极大地提高变电站运行的自动化管理水平、运行可靠性和经济性。针对某工厂变电站综合自动化系统的升级需求,研究并设计实现了改进后的变电站综合自动化系统,给出了一种组合数字滤波器与基本傅氏算法的改进微机保护算法,应用在变电站综合自动化系统中。现场调试结果表明所设计的变电站综合自动化系统能够实现对电气系统参数智能监控,满足变电站自动化需求。

The comprehensive computerized automatic system of transformer substation can improve the automatic manage- ment level, feasibility and economy of the operation of transformer substation. To meet the upgrading requirements of one of factories, the article did a research and analyzed revised system and put forward a modified method of a kind of digital filter and fourier algorithm. From the result of field tests, it shows the automatic system of transformer substation can fulfill the mo- nitoring electrical system parometer and meet the automatic requirement.
