Study of Bhakra reservoir operation

Integrated operation of the Beas-Sutlej system

“…The trade-off between irrigation and power ranges between 140 and 200 MW/RF. The trade-off between irrigation and power implied in the planned operation of the Bhakra reservoir in an average year is between 240 and 260 MW/RF (table 14, Rao & Ramaseshan, 1985). At higher firm power levels, the relative value of power may decrease indicating a higher trade-off.…”

“…Gross irrigation requirements for the Sutlej and Beas canals adopted by the Beas Designs Organization (aDo) are given in table 2. A comparison of the irrigation requirements of the Sutlej canal command with those of table 1, Rao & Ramaseshan (1985) reveals that there has been a slight upward revision of the requirements perhaps due to the increased crop water requirements of the high-yielding varieties.…”

“…This can be 207 diverted at Harike to irrigate the Be, as command. The Bhakra component of this system has been described in Rao & Ramaseshan (1985)and the interconnected system of the Beas, the Sutlej and the Ravi is shown in figure 1 of that paper. The inflows of the three rivers for a dependable year are summarized in table 1 and those for a mean year are shown in figure 1.…”

“…The planned operation of the reservoirs of the interconnected Beas-Sutlej system is described by Bhalla & Bansal (1975) and Lamba & Prem (1975). The operating policy of the system of reservoirs is the same as that of the Bhakra reservoir ( § 2.4, Rao & Ramaseshan 1985). In the original Beas project report, the Bhakra and Pong reservoirs were assumed to be depleted almost simultaneously to their dead pond levels, the firm power being 766 MW.…”

“…3.3b Power conversion factors: The power conversion factors (Kli, K2i, and K3) are calculated for each reservoir for each subperiod from the aDO data in table 3 and are shown in table 4. As in the study on the Bhakra reservoir (Rao & Ramaseshan 1985) their variation as a function of the actual reservoir level in each subperiod is ignored. Dehar is a constant head power plant and the power conversion factor is computed as 2.616 MW/cumec from the total power generated and the total flow through the plant in a year.…”
