building operation monitoring system at 110kV . substation

Southern Electricity Corporation (EVN SPC) is building an operation monitoring system (HMI) at 110kV substations to effectively exploit the invested equipment to connect to the SCADA/EMS system. of the Southern Power System Dispatch Center (A2), especially RTUs that have been equipped with HMI software in Flash cards such as RTU ABB-560. In March 2013, EVN SPC completed the construction of the first HMI system at 110kV Hoa Phu substation, Binh Duong province.

EVN SPC is continuing to build an operation monitoring system at 61 110kV substations equipped with RTU ABB - 560. This HMI system consists of 2 21-inch screens, which will show the following information:

* The overview screen shows the following contents:

Diagram of 1 fiber for the whole station; display an overview of device status, online measurement values ​​and alarms;
Perform device control;
Capable of switching to simulation mode and real operating mode (there are signs to identify between simulation mode and real operating mode);
There are buttons to link to the compartments to view the details of the compartments; has buttons that link to data connection displays, alarms, events, and chart views;
Show Local/Remote lock position of the whole station (if any);
There is a function to login and log out of the system.

* Data connection display:

Show the solution to get the signal (protocol or hardwire, which signal is hardwired and which signal is taken by protocol);
Display connection of IEDs;
Connection status of IEDs (connected or disconnected).
* Detailed screen of compartments:

Detailed display of device status, online measurement values ​​and alarms;
Show details of compartment-related information (type of equipment, manufacturer, ratio CT, VT...);
Perform control of devices in the compartment;
Capable of switching to simulation mode and real operating mode (there are signs to identify between simulation mode and real operating mode);
There are buttons to link to adjacent panes, overview screen, data connection display, alarms, events.
Shows the location of the Local/Remote lock of the pane (if any).
* Warning screen:

Display all system alerts;
Information displayed must be intuitive, easy to quickly recognize warning signals;
Instantly identify new alerts (with telltale signs);
There is a function to confirm new alarms;
There is a function to select each type of alarm, to select alarms of stations and compartments and devices;
Ability to retrieve past alerts.
* Event recording screen:

Display all system events;
Information displayed must be intuitive, easy to quickly recognize events;
Instantly identify new events (with telltale signs);
There is the function of selecting each event type, event selection of stations and compartments and devices;
There are buttons that link to overview screens, data connection displays, warnings;
Ability to retrieve past events.
The HMI system makes the most of the invested SCADA equipment, the operators can sit at the HMI computer to monitor the status of the equipment, alarms, real-time measurement data and control the equipment. device. For new construction 110kV substation in the coming period, this HMI system will be equipped with a part to create report forms to help operators not have to enter data into report forms such as: The current.
