To help prevent disruption in power transmission in Maragheh County in East Azerbaijan Province, a mobile substation will be synchronized with the national grid in June, deputy for planning and development in the provincial electricity company said.
"The 132 kilovolt equipment cost $470,000 and was purchased from a domestic company. It is being installed on a 3,000-square-meter plot," Maqsoud Zadehmahdi was quoted as saying by Paven, the Energy Ministry news portal.
"Mobile substations are an ideal solution whenever utilities and industries need interim grid connections and temporary power supplies," he said, adding that applications range from power supply during emergencies and outages to moving loads and integration of distributed or renewable generation.
Zadehmahdi noted that construction of a fixed substation normally takes three years, but mobile substations come in the form of ready-to-connect complete assemblies designed for easy mobility.
Nine mobile substations were synchronized with the national grid in March in Khuzestan Province.
The substations added 270 megawatts to Khuzestan's installed capacity at 2,000 MW.
Referring to other measures to reduce blackouts in the province, managing director of Khuzestan Regional Electric Company Mahmoud Dasht-Bozorg said. Twelve gas-insulated substations are being installed in the southern oil province.
"GIS systems cost twice as much as regular substations, but they play a key role in reducing power cuts in regions vulnerable to intense dust storms," he said.
A GIS uses dielectric gas and sulfur hexaflouride at moderate pressure for insulation. It is mostly used where space is expensive or not available.
