摘要
本文提出了配电系统微机反时限过电流保护的反时限、强反时限和极强反对限三种保护特性及数学模型、程序框图和整定计算方法。实例说明发展和推广微机反时限过电流保护的可能性和必要性。
The inverse time overcurrent characteristics and model for microcomputer-based distribution protection systems are presented. They are standard inverse time, very inverse time and extremely time. These characteristics can be independently selected. The program block diagram and setting method are also raised. A example is given and demostrates the possibility and necessity of dovelopment and application of microcomputer-based inverse time overcurrent protection to distribution systems.
