摘要
数字化、智能化、集成化、网络化是数字备用电源自动投切装置(简称备自投)的发展趋势,针对这一发展趋势,提出了一种新型的数字备自投装置整体解决方案,介绍了该装置的硬件设计、工作原理及几项关键技术。采用可编程逻辑的设计思想实现了灵活的备投方式;利用以太网方式实现了通信组网;利用全球定位系统(GPS)技术实现了硬件对时功能。该装置能自动跟踪变电站系统的运行方式,执行相应的备自投方案,保证供电持续可靠。
Digitization ,intelligence,integration and network are the development trend of standby power supply auto-switching device. A new solution of its design and implementation is raised. Its hardware design,operating principle and some key technologies are introduced. Flexible auto-switching way is realized by using programmable logic technology, communication network by Ethernet, and hardware clock synchronization by GPS （Global Position System） technology. It follows the operation pattern of substation system automatically and executes corresponding auto-switching scheme to ensure power supply continuous and reliable.
