微机保护算法测试软件系统的设计

A Testing Software for Algorithm of Microprocessor Based Protective Relay

随着近代微机保护的发展，涌现出了许多新的算法。但由于实际波形中含有大量的谐波分量甚至指数衰减分量，直接影响了这些算法的精度。本软件包用有衰减的直流、基波分量及谐波分量达加作为模拟波形，对电力系统实时系统进行全方位的模拟和测试，然后用空间图形直观输出以帮助用户精确地分析算法的优劣。

With the development of microcomputer protection, many new algorithms appear. Because real waves contain numerous harmonic wave and even exponentially.attenuating components, the accuracy of an algorithm depends on its filterability. In our software package, the imitative wave is constituted of an attenuating direct current element, a basic wave and harmonic waves, by which the real time power system is simulated and comprehensive tests of user's algorithms are performed. The result is graphically outputted so that consumers can audio-visually see the performance of the algorithm.
