Objectives:

The project aims at constructing a National Control Center (NCC) to operate and control the major power generating stations and the 400kV and 230kV Syrian transmission networks. The NCC will also provide immediate intervention in case of system disturbances in order to minimize disruption of supply to the loads and to ensure fast restoration of the system following the removal of such disturbances. In addition, it will supervise the tie lines connecting Syria with both Jordan and Turkey and will coordinate with the regional control centers in Hama, Qaboun and Aleppo with regard to the 66kV system.

Description:

The NCC will be located in a new building being erected about 100m from the existing national control center. The project, which is expected to be completed by the middle of 200 1, includes the following major components:

1. Supervisory Control and Data Acquisition (SCADA) System: which includes the supply and installation of the following: 

   1. A Central Control System to include basic SCADA programs.

   2. High speed mainframe computers and their peripheral equipment, capable of running the operational application programs by collecting information and data from the Remote Terminal Units (RTU's) located in the 400kV and 230kV substations.

   3. Control room equipped with system consoles. Each console consists of an advanced computer, Video Display Units (VDU's) and a control panel.

   4. The addition of equipment, including a training simulator, to the existing national control center .

   5. Power-supply units including power cables. 

   6. Emergency diesel generating unit.

   7. Spare parts, measuring equipment and special test equipment.  

2. Telecommunications Media between the Substations and the NCC: which includes the supply and installation of the following: 

   1. Powerline carrier (PLC) equipment required to establish communications between the remote and main 230kV substations.

   2. Electronic switches, telephone equipment and auxiliaries for all substations, whether existing or under construction.

   3. Microwave link between Adra (2) substation and NCC.

   4. Fiber optic network, and its accessories, to connect the various 400kV and 230kV substations with NCC.

   5. Telecommunications Management System (TMS). 

   6. Power-supply units including power cables.

   7. Spare parts, measuring equipment and special test equipment.

3. Special Application Programs: which include the supply and installation of programs for estimating electrical indicators, data analysis, performing short circuit and load flow calculations, automatic generation control, load forecasting and optimal power flow.

4. Optical Ground Wires equipped with fiber optic conductors (OPGW) to complete the communications loop in the Southern region, along with underground cable accessories.

5. Institutional Support and Training: which includes the purchase of advanced computers, a local area network and the training of technical personnel on the operation and control of the equipment supplied for the NCC, along with providing training in the areas of management, accounting and programming.

6. Consulting Services: which include the selection of the best system configuration, the supervision of project execution and attendance of witness tests at the manufacturers' facilities.

7. Civil Works and Means of Transportation: which involves all necessary works to equip the NCC in order to accommodate the necessary electrical equipment, and the purchase of field cars required during the supervision of the construction phase.
