电力工业在现代化进程不断深入的背景下得到了长足发展，而且电网的规模也逐渐扩大，为此，电力系统也逐渐成为国家现代化建设的重要前提。其中，继电保护是二次设备，使得电力系统运行更加安全与稳定。为此，文章对电力系统及其自动化问题展开了讨论，并且分析了与继电保护之间的关系，以110kV继电保护为例，阐述了在电力系统及其自动化中的具体操作。%The power industry has been greatly developed in context of the deepening of the process of modernization, and the scale of the power grid has been gradually expanded, for this, the power system has gradually become an important prerequisite for the modernization of China. Among them, the relay protection is the secondary equipment, which makes the power system run more safe and stable. To this end, the article discusses the power system and its automation issues, analyzes the relationship with the relay protection, and taking 110kV relay protection for example, elaborates the specific operation in the electric power system and its automation.
