摘要：
微机保护将朝着高可靠性、简便性、开放性、通用性、灵活性和网络化、智能化、模块化、动作过程透明化方向发展，并可以方便地与电子式互感器、光学互感器实现连接，同时，要跳出传统的“继电器”概念，充分利用计算机的计算速度、数据处理能力、通信能力和硬件集成度不断提高等各方面的优势，结合模糊理论、自适应原理、行波原理、小波技术和波形特征等，本文在分析了几种经典的继电保护算法，包括采样值积分算法、Mann-Morrison导数算法、Prodar-70算法、全周傅氏算法、半周傅氏算法等的基础上，引入一种新型的可以滤除直流分量的全周傅氏精确算法，该算法不仅完全保留了全周傅氏算法的滤波功能，而且对衰减直流分量也具有很强的滤波特性，此外，本算法采用一个周波或一个周波加一个采样点的数据窗，就可以计算出各谐波分量的幅值，算法简单。在引入新算法的同时，设计了基于DSP TMS320LF2407A的发电机保护装置。
Abstract
The protection for main power equipment is important to the stability and security of power system. Because of the electric power, my country has planned to establish some power plants. It is very important and applied to study the protection of generator.
With the development of micro-computer, the computer technology has spread all over every field about protection of generator ,such as the studies of protection scheme based on micro-computer and manufacture of relay, This thesis includes; To select appropriate algorithms is one of the basic issues of micro- processor-based relays. When select algorithms, we should consider two issue, speed and precision. After analyzing the several classic algorithms, including Sampling Multiplication Algorithm, Mann-Morrison, Algorithm, Prodar-70 Algorithm, Holo-cycle Fourier Algorithm and Half-cycle Fourier Algorithm, this paper present a new kind of Holo-cycle Fourier Algorithm which can filter the decaying DC component. The new algorithm is simple and can be applied to microprocessor relay protection to pick up harmonics. Based on the new Holo-cycle Fourier Algorithm, the generator relay is developed using DSP TMS320LF2407A.
This paper discusses the system structure of generator-based on microprocessor relay.
