Application of Programmable Logic Controller in GIS Switchgear Intelligent Control System
Wang Qingqing · Jiangsu Electrical Apparatus · 2008
Combining system hardware design with programming plan, introduction was made to a set of intelligent control system composed of converter power source, programmable logic controller (PLC), human machine interface (HMI), gas-insulated metal-closed switchgear (GIS) etc from the perspective of automatic control and intelligentized maintenance. Compared with traditional GIS control system, it is small, more reliable, good in real-time, easy to maintain and so on.
