摘　　要：当前,人们在生活、工作中的各个领域中都离不开电力。由于电力用户数量的增长,对电能需求量也随着时代而日益增大,在这种背景下加强对供电系统的建设在一定程度上就能够降低电能负荷。电力二次输入电路的使用直接关系到对电能整体系统的影响作用和稳定性,所以对动力系统来说是非常重要的功能性元器件,但在实际使用中其故障的出现概率却相对较高。为提高动力系统的稳定性,那么则必须对其电气二次回路故障问题进行全方位的系统分析,以便使其故障率限制在最低点。为了达到动力系统的平稳运转,就需要实现继电保护系统的二级电路,以发挥其功效。At present,people cannot live and work without electricity in various fields.Due to the growth of the number of power users,the demand for electric energy is also increasing with the times.In this context,strengthening the construction of the power supply system can reduce the power load to a certain extent.The use of power secondary input circuit is directly related to the impact and stability of the overall power system,so it is a very important functional component for the power system,but its failure probability is relatively high in actual use.In order to improve the stability of the power system,it is necessary to conduct a comprehensive system analysis of its electrical secondary circuit faults,so as to limit its failure rate to the lowest point.In order to achieve the smooth operation of the power system,it is necessary to realize the secondary circuit of the relay protection system in order to play its role.
