摘要
传统变电站自动化系统的防越级跳闸的解决方案都存在着各自的缺陷,不能够完美地解决煤矿电网越级跳闸问题,必须考虑新的保护原理,智能变电站为这一问题的解决带来了新的契机。文章基于智能化变电站全站信息共享的特点,提出了基于采样值差动判据的智能差动保护。
The solutions of anti grade trip have their shortcomings in the automation systems of traditional substations.The anti grade trip in the mine grid can not be solved perfectly.The new protection principle must be considered. The intelligent substations bring new opportunities in order to solve the problem. In the paper, based on the total information sharing characteristics in the intellgent substation, the intelligent differential protection is put forward based on the sampling value differential criterion.
