摘要
针对抗干扰、电磁兼容等实际问题,对保护装置可靠性设计的内容进行定性研究和分析,分别从设计原则、影响可靠性的因素和软、硬件抗干扰措施等方面进行探讨,讨论多种硬件和软件提高可靠性的措施。最后,结合工程设计中的广西某水电站220kV输电线路保护的应用实例,就目前的技术水平介绍其实现的可能性。
In view of the actual problems of interference rejection and electromagnetic compatibility,the paper does a qualitative research on the contents of reliability design for protection device,which covers design principle,factors influencing reliability and anti-interference measures for hardware and software.Then it discusses the measures to improve the reliability of hardware and software.Combined with the engineering design case study on 220 kV transmission line protection for a hydropower station in Guangxi,China,the feasibility of its realization is predicted.
