| Description | The trend toward increased electrification inside the modern power plant is evidenced by the Avon supercritical-pressure unit. The application of electrical controls to economically and reliably accomplish equipment protection and interlocking functions directly, or in combination with hydraulic and pneumatic control devices, has been demonstrated on commercial subcritical pressure units. They will continue to do so on the supercritical-pressure units. 1. Basically, the over-all trip protection for the supercritical-pressure turbine and steam generator is not radically different from that for large subcritical units, except for several important additions. 2. Automatic transfer of selected auxiliary motors to the start-up source becomes more important. 3. The monotube once-through steam generator requires a large number of hydraulic and remotely operated electrical controls. 4. Automatic starting of boiler feed pump prime movers and other auxiliaries may increase the over-all reliability of the main unit while adding little complexity to the control system which is designed for complete remote operation. 5. The complexity and number of electrica controls required on main control room panels for a supercritical unit far exceeds those required for a large conventional highpressure high-temperature unit. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
