How does the Rudbar Lorestan Dam generate power?

The Rudbar Lorestan Dam operates as a diversion-type hydroelectric power station, utilizing the natural topography of the Rudbar River, a tributary of the Dez River in Lorestan Province, Iran. The system relies on a concrete gravity dam structure to regulate water flow and create the necessary hydraulic head for power generation. This design allows for the efficient conversion of potential energy from the elevated water reservoir into kinetic energy, which drives the turbine-generator units located in the powerhouse. The facility was completed on September 15, 2016, and officially began operating on May 31, 2017, marking the culmination of a project initially scheduled for 2013. The dam is operated by the China Gezhouba Group, which manages the operational parameters to optimize electricity output based on seasonal water availability and grid demand.

Technical Specifications

Each unit has an installed capacity of 225 MW, contributing to the plant's total installed electricity generating capability of 450 MW. The Francis turbine is a type of reaction turbine that combines radial and axial flow concepts, making it highly efficient for medium-head applications. In the Rudbar Lorestan configuration, the water is channeled through penstocks to the turbines, where the pressure and velocity of the water spin the runner blades. The rotational mechanical energy is then converted into electrical energy by the synchronous generators.

A critical parameter for the efficiency of the Rudbar Lorestan plant is its design head, which is specified as 430.7 meters. This significant vertical drop between the water source and the turbine inlet provides substantial potential energy, allowing the 225 MW units to generate power effectively even with moderate flow rates. The concrete gravity dam plays a vital role in maintaining this head by resisting the water pressure through its own weight, ensuring structural stability and consistent water level management. The integration of these components—gravity dam, high-head penstocks, and vertical Francis turbines—creates a robust hydroelectric system capable of delivering reliable baseload or peaking power to the regional grid in Lorestan Province.
