The operator of Bao Loc 220kV substation recording parameters by IPAD at the existing operating room
To meet today's urgent requirements, upgrading the existing supervisory control system to meet the requirements in reliability, safety, power quality, and energy saving, and at the same time is the foundation for the development into an unmanned substation model, which is a premise for the development and formation of a smart grid system in the near future.
The measurement protection control system equipped in this phase meets the requirements in connection with the existing system and complies with the current regulations and standards with the following scale: the control system will be equipped with a new computer control system installed inside the substation in a single LAN configuration to replace the traditional one. The newly-equipped control system ensures the connection of Scada signals to the control centers and the connection of monitoring signals to the mobile operating team, suitable for remote control and unmanned operation.
The protection relay system will replace and add new protective relays in accordance with IEC 61850 communication standard, in accordance with the current regulations of EVN and EVNNPT. The information and SCADA system will be fully equipped with dual gateways to transmit SCADA signals to dispatching levels.
PTC will build new outdoor Bay-housings (BH) to install new control and protection cabinets; Re-arrange the protective panel cabinet in the control house and renovate the indoor and outdoor cable trench system to lead cables into the newly-built control houses.
Regarding fire protection, when the project is put into operation with the model of an unmanned substation, the fire protection system will be monitored and controlled remotely to meet the requirements of being able to control and extinguish fire incidents in place.
Mr. Huynh Quang Thinh - Head of Technical Department (PTC3) said: So far, Pleiku 500kV, Krong Buk 220kV, Quy Nhon 220kV, Bao Loc 220kV substations are being urgently completed in upgrading the control system to protect substations. In particular, after the completion, it is easy to convert the substation operation method to the model of an unmanned substation so as to reduce the number of operation management staff and meet the requirements of implementing Industrial Revolution No. 4 and digital conversion.
