摘要
本文论述一种用集成电路来实现具有最小定时限的反时限曲线的新方法。阐述了四段曲线拟合法的实现方案及拟合误差分析,而且还讨论了实施电路对减少误差所采取的措施。本方案所采用的曲线拟合法在集成电路保护实现领域内是独特的,尤其是在实用性、可靠性以及准确性上都有较新的突破。
A new method for implementing inverse time protection with definite minimum time using integrated circuits is presented in this paper. It details the implemented scheme of four-section simulated curves and error analysis, and also discusses the method for reducing error. This scheme is unique in protection area. New progresses arc made on practicability, reliability and accuracy.
