Instrumentation

The controlling system and instrumentation tools of Masjed Soleiman powerhouse is designed as non-centralized in four levels of controlling, including local controlling boards, UCB (Unit Controlling Board), CCR (Central Controlling Room) and dispatching center; in a way that the local controlling has the highest priority and this priority decreases from CCR to UCB and dispatching center. The most common operation level is dispatching center and then there are central controlling room, UCB and local centers. These centers are limited to the special testings, repairs and maintaining. Through controlling system and with the help of created interfaces between controlling system and several equipments, each units can work on the basis of the following models; Line Charging Mode, Synch-Condenser, Generators, Standby Rolling and Standstill.
Synchronic equipments for each unit are installed in controlling board and the possibility of synchronizing is available from CCR, UCB and dispatching centers.
It is possible to control each powerhouse units individually from dispatching center and at the same time a series of units can also be jointly controlled.
The data servers can record long-term events in powerhouse and the operators can have access to this information through their computers.

Quarries and their specifications

Four zones were considered for this purpose. In the end, among these four zones Simband quarry was selected, because of the good amount of stones and their suitable qualities. The amount of stones in this area has been estimated to be more than 3 millions m3. The distance of this area to the dam site is 8 km along with the existing public road. For concrete, the required sand is taken from quarries near Shushtar and the deposit of excavated sand of Kooshk quarry.
