Dr. H.R. Sharma has carried out several innovations in the planning and design of hydro power and water resources projects:
Developed an unique control system for Chibro Khodri Hydro power stations operating in Tandem: The Chibro (240 MW) and Khodri (120 MW) hydro power stations are fed through a common water conductor system consisting of 7 m diameter and 12 km long pressure tunnel without any appreciable storage in-between to act as a downstream surge tank for Chibro Power House and an upstream reservoir for the Khodri Power House. The latter is fed through a 6 km long head race tunnel. The system itself is unique in the world. For the safe and optimum operation of the system, a unique control system was evolved after carrying out detailed mathematical model studies. The Chibro-Khodri system came into operation in March 1984. Since then, the control system is functioning satisfactorily. This has eliminated the construction of the diversion dam and the sediment excluding arrangement for the Khodri Power House resulting in a saving of hundreds of millions of rupees. The successful performance of the system has encouraged adopting similar layouts at other hydro power complexes. For example, it has been decided to eliminate the diversion dam and the desilting arrangement at the proposed Rampur Hydel Scheme (412 MW) located downstream of the 1500 MW Nathpa-Jhakri underground Power Station under operation on river Satluj in Himachal Pradesh. This would result in saving of about Rs. 1000 millions the Rampur Hydel Schema has since been commissined.
Evolved unique designs for sediment excluding arrangement at intakes for run-of-the-river hydro power schemes. One of the greatest problems experienced at these schemes is the sediment passing through the intake, the water conductor system, the turbines and various under water parts causing blockages,severe erosion, drop in efficiency, reducing the machine availability and thereby the overall energy generation. In some cases the power house has to be closed for a number of days or weeks and in some cases even for months. Developed a unique and almost 100% efficient design for sediment exclusion at Ichari intake under Yamuna Hydel Scheme Stage-II, commissioned in 1975. The scheme has been functioning efficiently since then, the prototype efficiency being more than 95%. The design has become more or less a standard model and is being adopted for a large number of hydro-electric schemes.
Developed for the first time exact mathematical solution for differential equation of mass oscillations considering tunnel friction for restricted orifice surge tank for the case of total load rejection. The derived equation enables to determine the maximum surge height directly curtailing the long trial and error procedure. The derived equation when reduced for the case of simple surge tank tallies with the well known equation derived by Charles Jaeger.
Other innovations in the designs: To affect economy and to curtail the overall gestation period of hydro power projects, a number of innovations have been introduced in the designs without compromising with the safety and the efficiency of the schemes. For example, surge tanks which are costly structures and take considerable time to construct have been eliminated at two very important hydro power projects having installed capacity of 600 MW and 2000 MW. Use of diversion tunnels as spillway tunnel is also an equally important innovation introduced by Dr. Sharma.
Pioneering work in tidal power development in India: For the first time in the country, the highly specialized and complex investigations and studies for a 900 MW tidal power project in the gulf of Kachchh on the Western Coast of India were carried out and detailed feasibility report prepared. An entirely new approach was suggested for the execution of the project. Close interaction was held with the leading experts in the world. The final recommendations were discussed in an International Symposium held in New Delhi in 1988 and were widely acclaimed. The project has since been entrusted to the National Hydro Power Corporation Limited for execution
Evolved the most economical section of the silted 300 cubic meter/sec capacity Ganga Canal after the Alaknanda Tragedy of 1970. The adopted design not only resulted in saving of more than 15 Million rupees but also made it possible to run the canal in time for Rabi Crop. The Ganga canal is the back bone of Western Uttar Pradesh, India. The Ganga Canal built in 1854 is one of the oldest and the most important irrigation system in India. On 20th July there was a cloud burst in the Alaknanda Valley causing a huge slide resulting in the formation of a temporary earthern dam which subsequently gave way causing havoc in the valley. Hundreds of lives were lost, considerable length of the road was washed off, several bridges were damaged and the Ganga canal was completely silted in its first 11 km reach. There are eight hydro power stations on the canal below the reach. Designed the most economical section for the silted canal which was discussed at the highest level including Union Minister of Water Resources.
