Digital Substation Automation Operation System is HMI(Human Machine Interface) system which provides operating information on each facility in the IEC 61850-based SA (Substation Automation) digital substation to the operator.
As a device to provide operator interface on SA electronic power facility, It calculates operating information data from field devices such as IED and RTU while processing database and showing acquired data and event history to the screen for the operators. It calculates operating information as data from devices in the field as received from IED and RTU, while performing to process database and showing acquired data and event history to the screen so that the operator can recognize them.
This device acquires and processes operating information of electronic power facilities in the substation. Receiving It transmits data received from IED and RTU to substation and DAS. At the same time, it transmits data to IED and RTU receiving the control order and actually control them.
This prints operating data such as event/report.
This is a server where standard time is received from GPS to synchronize time with all the SA system devices in the substation.
This is used to connect devices such as IED and SA operating devices in the substation, monitoring/diagnosis devices and information connecting devices. This switch is composed of access switch connected with each devices and backborn switch connecting each access switches.
It is available to monitor and diagnose operating information with communication regulations as defined in IEC 61850 standards. All the data transmitted between SA operating device and IED are saved. Accessibility is granted through web interface. Network status, monitoring status of report and GOOSE data are shown on the screen. Re-saving is available by filtering saved data upon preferred time / device.
This device is comprised of SA system part (main/backup, E/S) including the information connecting device and SA Ethernet switch part.
