System Dispatch Center

img-system-dispatcher-center-sample1.jpg

The System Dispatch Center, via SCADA/EMS system, coordinates generation, transmission and distribution control into one centralized control center hence achieving optimal performance of the power system. Our customers particularly benefit from the Distribution Automation (DA) functions in terms of power supply quality and reliability.

The SCADA system is based on an open system architecture that uses the most updated international standards. It allows expansion and integration with other systems without any barrier.

An Energy Management System (EMS) is incorporated to ensure optimization, safety and reliability of the network. Analysis is performed regularly, providing advises to Dispatchers to get the highest efficiency of the power system.

The implementation DA functions allows CEM to reduce the number of power interruption with real-time monitoring the whole 11kV distribution network operations.

On the other hand, the duration of the power interruption is drastically shorter than before, as remote controls replaced site interventions. Remote isolation and quick power restoration can now be performed easily from the control room, which greatly helps in reducing the average interruption time.

Considering the Systems Dispatch Center has been in operation for more than 15 years and its location, office space, auxiliary systems and equipment are no longer adequate to accommodate the current and future needs, CEM is undergoing a project to build a new dispatch center, at the same time, to upgrade our SCADA/EMS/DA systems using new and state of the art technologies to sustain the future development.

The new dispatch centre will be located at the Coloane Power Station. The disassembling and removal of the equipment from the original building of the construction site started in late 2016 and the original building is ready now for demolition which is planned to start later on. Subsequently, new building construction will begin afterwards. Once the project is completed, this will be the first LEED-certified green operation centre built by CEM and the current control center at Porto Exterior will become the Backup Dispatch Center.
