随着电力工业的不断发展以及市场化改革的深入,人们对供电质量和电网经济安全运行的要求越来越高。变电站是输电和配电网络的重要节点,对保证电力系统安全稳定运行起着举足轻重的作用。因此,数字化变电站的发展将对变电站自动化运行和管理带来深远的影响。介绍了数字化变电站保护出口矩阵的形成方法,将传统继电保护原理与可编程逻辑结合起来,做成一个"黑匣子",并从数学角度设计矩阵的形成及优化方法,通过MATLAB进行仿真和验证,证实是可行的,为数字化变电站保护模块化的设计和应用打下了基础。
A Research on the Matrix of the Digital Substion Relay Protection
The power industry development and the deepening of market-oriented require the electricity supply quality and safe operation of power grids economic improve. Substation is an important node in transmission network, so it plays an important role in safe and stable operation of power system. Therefore the development of digital substation will have far-reaching implications in substation automation, and the important significance of the technical and economic significance. My topic is to discuss how to build the matrix of the digital substa tion relay protection. That is, to combine the classic protection principle with the programmable logic and make them as a "Black Box" which in the angle of the mathematical method, and use MATLAB to simulate and verify.
