Research on Anti Over-ride Trip System for High-voltage Power Grid of Coal Mine

With the foundation of analyzing the causes of over-ride trip caused by underground high-voltage power network fault, we propose a kind of anti-ride trip method of high-voltage power grid based on the internet of things technology. In addition to briefly discuss the structure of the system and the logical judgment of the software, the paper also proved that the system can meet the underground requirements of the reliability, selectivity and economy from many aspects.
