Relay protection method and device based on multi-core CPU processing matrix calculation

The invention discloses a relay protection method and device based on multi-core CPU processing matrix calculation. One core of a multi-core processor is used for executing a protection program; one core sets interruption time according to matrix calculation task time consumption, executes a matrix calculation program and performs data interaction with the protection core; a core runs a hypervisor. And a new protection principle based on matrix calculation is realized on the basis of not increasing the protection interruption time consumption of the original protection core. 本发明公开了一种基于多核CPU处理矩阵计算的继电保护方法及装置，使用多核处理器的一个核执行保护程序；一个核根据矩阵计算任务耗时设置中断时间，执行矩阵计算程序，并与保护核进行数据交互；一个核运行管理程序。在不增加原有保护核保护中断耗时的基础上实现基于矩阵计算的保护新原理。
