Efficiency of Pumped Storage Hydroelectricity

on 17/01/2023

The generally low energy thickness of pumped storage frameworks requires either huge streams as well as huge contrasts in stature between supplies. The best way to store a lot of energy is by having a huge waterway found moderately close, however as high above as could really be expected, a second waterway.
In certain spots this happens normally, in others one or the two waterways were man-made. Projects in which the two supplies are artificial and in which no normal inflows are engaged with either repository are alluded to as closed-loop frameworks.
The main use for pumped storage has generally been to adjust baseload powerplants, yet may likewise be utilized to decrease the fluctuating result of discontinuous energy sources. Pumped storage gives a heap on the occasion of high power results and low power interest, empowering extra framework top limit. In specific wards, power costs might be near nothing or sporadically negative on events that there is more electrical age accessible than there is load accessible to retain it; despite the fact that at present this is seldom because of wind or solar-based power alone, expanded breeze and sun based age will improve the probability of such events. Traditional hydroelectric dams may likewise utilize pumped storage in a crossover framework that both creates power from water normally streaming into the supply just as putting away water siphoned back to the repository from underneath the dam.
Miniature applications for pumped storage could be based on streams and inside frameworks, for example, drinking water organizations and fake snow-making foundations. In such a manner, a tempest water bowl has been solidly carried out as a savvy answer for a water repository in a miniature pumped hydro energy stockpiling. Such plants give appropriated energy stockpiling and conveyed adaptable power creation and can add to the decentralized mix of discontinuous environmentally friendly power advancements, for example, wind power and sunlight-based power. Alongside energy, the executives, pumped storage frameworks assist with controlling electrical organization recurrence and give hold age. Warm plants are substantially less ready to react to abrupt changes in electrical interest, possibly causing recurrence and voltage unsteadiness. Pumped storage plants, like other hydroelectric plants, can react to stack changes in no time. In open-circle frameworks, unadulterated pumped storage plants store water in an upper supply with no normal inflows, while pump back plants use a mix of pumped storage and customary hydroelectric plants with an upper repository that is renewed to a limited extent by regular inflows from a stream or waterway. Now and again of low electrical interest, an overabundance age limit is utilized to pump water from a lower source into a higher supply. At the point when a request develops, water is delivered once again into a lower supply (or stream or waterway) through a turbine, creating power. Reversible turbine-generator gatherings go about as both a pump and turbine (typically a Francis turbine plan). Practically all offices utilize the tallness contrast between two water bodies. Pumped storage hydroelectricity permits energy from discontinuous sources, (for example, sunlight-based, wind) and other renewables, or abundance power from nonstop base-load sources (like coal or atomic) to be put something aside for times of more popularity. The repositories utilized with pumped storage are minuscule when contrasted with customary hydroelectric dams of comparable power limit, and creating periods are regularly not exactly a large portion of a day. Some have proposed little pumped storage plants in structures, albeit these are not yet efficient. Additionally, it is hard to squeeze enormous supplies into the metropolitan scene. In any case, a few creators safeguard the mechanical effortlessness and security of water supply as significant externalities. Alongside energy, the executives, pumped storage frameworks assist with controlling electrical organization recurrence and give hold age. Warm plants are considerably less ready to react to abrupt changes in electrical interest, possibly causing recurrence and voltage flimsiness.n

A couple of cakes were cut in the event to celebrate the birthday of one of the kids at SOS village. An especially customized cake was ordered to uplift the environment. After a lot of fun with the children, the event ended with the vote of thanks by Dr. Umair Ahmed Korai to the chief guest, guest of honor, event collaborators, volunteers, and participants followed by shield and certificate distribution, and lunch. From an adult to a kid everyone was overjoyed with the expression of love and warmth, and everyone went on their ways with happy memories and a new ignited spirit of helping the underprivileged people of our society.n

Robots in SIUT
First robotic surgery, training center becomes reality

on 17/01/2023

Sindh Institute of Urology and Transplantation (SIUT) has set up a robotic surgery and training center. Chief Minister Syed Murad Ali Shah inaugurated the center—the one which has brought yet another distinction for the institute.
In 2017, SIUT embarked on its Robotic Surgical Program in collaboration with the Civil Hospital Karachi.
The robotic Surgical Unit that the institute established was funded by Bashir Dawood, the Sindh government, and SIUT North America.
SITU website says the donation by Bashir Dawood for the Robotic Unit was to honor his family friend Kassim Parekh, a renowned banker who became Governor of the State Bank of Pakistan.
Recently two robotic surgical units were acquired by SIUT from Cambridge Medical Robotics (CMR). These are currently used by many centers in Europe, the Middle East, India, and Latin America.
This acquisition is part of the SIUT philosophy to remain at the cutting-edge of technology. Robotic surgery is considered the future generation of surgical sciences.
Robotic procedures are associated with less pain, less blood loss, and faster recovery. Patients are discharged within a few days and can resume regular activities.
The unit has started with urological surgeries, to be followed by colorectal and gynecological surgeries. Thus far more than 1000 Robotic Surgeries have been performed at the department.
SIUT had already planned for a regional Robotic Surgical Training Center to train the next generation of surgeons in this state-of-the-art technology both from within Pakistan and the region, the institute says.
Chief Minister Shah said robots performed surgery on organs that are difficult to reach by hand. “It is a revolution.”
Shah congratulated Dr. Adib Rizvi, the founder of SIUT and an internationally acclaimed surgeon.
Shah said he was proud that his government took a lead in robotic surgery in the country. He hoped more centers would be established in the country and offer young doctors to use modern tools and methods.
He also recalled that the first robot was acquired by the Sindh Government in 2017 from Intuitive Surgical Company, USA – The da Vinci System. It was used both by Dr. Ruth Fau, Civil Hospital, and SIUT and later the Robot was moved to a dedicated Robotic Surgery Unit in SIUT. – ER Report

Need to convince Sindh on Kala Bag Dam: Imran Khan

on 17/01/2023

Although he is not the first prime minister to believe that Kala Bag Dam is a very good site for water storage, Imran Khan thinks the people of Sindh should believe this dam would not affect the province.
While addressing as chief guest at an International Symposium on Hydropower Development in Pakistan the premier said that China has constructed 5,000 dams, but Pakistan had built only two dams in 1960.
The prime minister said that there is no doubt that the country needed water storage and the Kalabagh dam is at a very good site for this purpose. However, there is a need to convince the people of Sindh on the Kalabagh dam that its construction would not have any adverse impact on Sindh’s water.
Prime Minister Imran Khan deplored that the country has suffered huge economic loss owing to the negligence of not constructing water dams.
The prime minister added that due to this negligence, the country suffered losses because when fuel prices increase in the international market, the price of electricity and other things also increases in Pakistan. Consequently, the people have to bear the burden, he added. The prime minister said that there is inflation in the country because the hike in the prices of electricity increases the cost of everything. “If the country would have been making electricity through water – hydropower – there would not have been inflation of this level.”
He said that unfortunately, this was happening because of the absence of long-term planning. He said the long-term planning of China is behind its economic strength. He said that his government’s planning was not election specific but was about long-term for the benefit of the country and this has been the precise reason that a “decade of dams” is being celebrated. He said that the present government considered that the country needed water storage to meet the needs of the growing population. “We have to cultivate more land and water storage is critical for it.”
The premier said that there is huge land in DI Khan besides hundreds of thousand-acre barren land in Balochistan. He said that ‘10-year dams’ would double the water storage and help cultivate the barren land besides dealing with climate change issues by producing clean energy through water.
“We are also producing cadres of engineering,” he said, adding that tunnel technology is very important for the promotion of tourism. He said that Switzerland has made its mountain accessible for tourism through tunnel technology.
