介绍了兴义地区首座数字化变电站的特点,即一次设备智能化,二次设备网络化。自动化系统的逻辑层次及其功能:过程层的智能化,间隔层的可靠传输控制以及站控层的监控分析等。通过数字站和常规站在技术和经济方面的比较,说明了数字化变电站在安全性、可靠性、测量精度、抗干扰性能等方面的优势。
Introduced Xingyi first digital substation features, namely, a device intelligence, network equipment secondary. The logical hierarchy of automation systems and their functions: the intelligentization of the process layer, the reliable transmission control of the bay floor and the monitoring and analysis of the station-controlled floor. The technical and economic comparison between digital and conventional stations illustrates the advantages of digital substations in terms of safety, reliability, measurement accuracy and anti-interference performance.
