RGTPP is located near Ramgarh Town district head quarter, Jaisalmer (Rajasthan), which is largest district of the state. Its installed capacity at about 60 km from is 270 MW. And this plant is located in largest state of India, based on area
There was problem in maintaining desired quality standards in electric supply to Jaisalmer on account of excess losses because of longer transmission lines. To rectify above problem and to utilize available natural gas in this area RGTPP was established in this border district whose existing capacity is 270 MW.

In electric power generation a combined cycle is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy, which in turn usually drives electrical generators. The principle is that after completing its cycle (in the first engine), the temperature of the working fluid engine is still high enough that a second subsequent heat engine may extract energy from the waste heat that the first engine produced. By combining these multiple streams of work upon a single mechanical shaft turning an electric generator, the overall net efficiency of the system may be increased by 50–60%. That is, from an overall efficiency of say 34% (in a single cycle) to possibly an overall efficiency of 51% (in a mechanical combination of two cycles) in net Carnot thermodynamic efficiency. This can be done because heat engines are only able to use a portion of the energy their fuel generates (usually less than 50%). In an ordinary (non combined cycle) heat engine the remaining heat (e.g., hot exhaust fumes) from combustion is generally wasted.
Combining two or more thermodynamic cycles results in improved overall efficiency, reducing fuel costs. In stationary power plants, a widely used combination is a gas turbine (operating by the Brayton cycle) burning natural gas or synthesis gas from coal, whose hot exhaust powers a steam power plant (operating by the Rankine cycle). This is called a Combined Cycle Gas Turbine (CCGT) plant, and can achieve a best-of-class real (HHV - see below) thermal efficiency of around 54% in base-load operation, in contrast to a single cycle steam power plant which is limited to efficiencies of around 35–42%. Many new gas power plants in North America and Europe are of the Combined Cycle Gas Turbine type. Such an arrangement is also used for marine propulsion, and is called a combined gas and steam (COGAS) plant. Multiple stage turbine or steam cycles are also common.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

Abstract
I have completed my vocational training during the period 09-06-2014 to 08-07-2014 from
RGTPP,Jaisalmer. In this report the main emphasis is on the Power Generation Process.
In the starting of this report the introductory aspects of RGTPP allover India has been
covered. Later I have explained the principle of operation and basic equipments used for the
generation of power.
Recognizing its excellent performance and vast potential, Government of the India has
identified RGTPP as one of the jewels of Public Sector 'Navratnas'- a potential global giant.
Inspired by its glorious past and vibrant present, RGTPP is well on its way to realize it's
vision of being "A world class integrated power major, powering India's growth, with
increasing global presence".
A Combined Cycle Power Plant produces high power outputs at high efficiencies (up to 55%)
and with low emissions. In a Conventional power plant we are getting 33% electricity
only and remaining 67% as waste. By using combined cycle power plant we are getting 68%
electricity. The basic principle of the Combined Cycle is simple: burning gas in a gas turbine
(GT) produces not only power – which can be converted to electric power by a coupled
generator – but also fairly hot exhaust gases.
