Visualization Research of Smart Substation Secondary Safety Measures

[摘要] The smart substation adopts the network communication rather than the traditional electric cable, which makes the traditional secondary electric circuit terminal into a loop of virtual terminal and then the entire secondary system became a "black box", thus causes a lot of problems and difficulties into the operation and maintenance of smart substation. However, little attention has been paid to the visualization of secondary safety circuits for smart substations. In this paper, a portable device based on the characteristics of the secondary circuits and needs of the current secondary safety measures for smart substation was designed to realize the visualization of the device information, the control circuits and the safety circuits. Finally, the secondary security measures of smart substation were normalized and illustrated based on the first set protection of 220 kV line space.
