智能磁力启动器保护算法的研究

Research on Intelligent Magnetic Starter Protection Algorithm

微机保护算法的好坏直接影响到综合保护的精度和速度,所以需要根据保护对象选择一种最优的算法。文章以智能磁力启动器综合保护装置为研究对象,对全波傅氏算法和半波傅氏算法进行了分析和比较,提出一种适用于本保护器的半波傅氏修正算法,仿真结果验证了本算法的准确性。

The quality of the microcomputer protection algorithm affects the synthesis protection precision and the speed directly, so it needs to choose the optimal algorithm according to the protection object. Analyzes and compares the full wave fourier algorithm with the half- wave Fourier algorithm on intelligent magnetic starter synthesis protective device. The half- wave Fourier revises algorithm which is suitable to this protector are put forward. The simulation result has confirmed this algorithm accuracy.
