THE National Grid Corp. of the Philippines (NGCP), the country’s sole power-lines concessionaire, said on Friday it has completed the upgrade of its Energy Management System (EMS) in the Visayas this year.
The NGCP said the completion of the EMS is in line with its efforts to build a stronger transmission for a stronger nation. It said the upgrade of system operations facilities in the Visayas is part of a nationwide project that improved the capability of and integrated NGCP’s National Control Center with its Regional Control Centers.
The NGCP said the project adopted the use of OPEN 3000, a state-of-the-art operating system that facilitates the effective monitoring and control to ensure the balance of power supply and demand.
The agency said the upgrade was necessary to replace obsolete hardware and overloaded system software in order to increase system reliability and performance, provide complete system data by accommodating new stations, and integrate the electricity market functions into the EMS.
The NGCP said the EMS integrates applications that are needed to manage the power transmission network.
A major component of the EMS, the NGCP said, is its Supervisory Control and Data Acquisition (Scada) system, which is a collection of equipment and software that facilitates control of remote devices, acquisition of real time data on power demand, capacity of connected power plants and other power-system parameters.
The NGCP said the Scada/EMS upgrade in Luzon and the Visayas has a combined project cost of P189.4 million. The upgrade in Mindanao, where the regional control center has been moved from Iligan to Cagayan de Oro, cost P126.5 million.
The NGCP earlier said it continues to strengthen the power transmission network in Leyte, which is aimed to meet the increasing power demand and improve system reliability. Among its ongoing projects this year is the Visayas Substation Expansion I Project, NGCP said the expansion includes the installation of a new 100-megavolt ampere transformer at Ormoc substation in Leyte.
The NGCP said the transformer is set to be energized in December 2012.
It said the projects in the area that are in their preconstruction stage include the Visayas Substation Reliability Project I, which involves the installation of a new transformer at Maasin substation in Southern Leyte.
The NGCP said the Ormoc-Babatngon 138-kiloVolt (kV) transmission line project involves the construction of a second circuit transmission line and its associated high-voltage equipment at the Ormoc and Babatngon substations.
The NGCP said another project, the Ormoc-Maasin 138-kV transmission line project, covers the stringing of a second circuit, and installation of related equipment at the Ormoc and Maasin substations.
The agency said it also implements the rehabilitation of its 69-kV transmission lines in the area.
Since last year, the NGCP said a total of 617 wooden transmission poles have been replaced with steel poles.
The rehabilitation, the NGCP said, is expected to increase line reliability and significantly lessen the probability of line outages, especially during extreme weather conditions.
To ensure continuous power services, the NGCP has appealed for public support in the prevention of pilferage, sabotage, grass fires and kite flying near transmission and distribution lines.
The NGCP is a privately owned corporation in charge of operating, maintaining, and developing the country’s power grid. It transmits high-voltage electricity through “power superhighways” that include the interconnected system of transmission lines and towers, substations and related assets. source
