| Abstract | This paper proposes a PC based data acquisition and load control system (DAALCS) to fulfil load management functions for a high voltage load customer. A programmable logic controller (PLC) associated with a digital power meter has been applied to fulfil major application functions of DAALCS. In the data acquisition subsystem, two PLCs with redundant configuration are responsible for directly collecting power measurements via star connection telephone network with real time mode. 15 digital power meters with standard RS485 protocol are installed on each building substation to record more than 20 parameters for data acquisition subsystem. In the load control subsystem, six sets of PLCs with the mixture of PLC network and RS 485 channel are constructed to execute load control schemes. The load control schemes are composed of load shedding for demand monitoring, cycling on/off load control, timer control, and direct load control. The proposed system has been successfully installed and continuously operated on an academic power system. The statistical data retrieved from the database shows that the DAALCS can effectively reduce the daytime peak load during the summer season and significantly save electric energy consumption. |

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.
