Some of the problems which make operation of the inter-connected power systems difficult even at the regional level are the growing proportions of thermal power plants as compared to hydro. Poor power management has resulted in high transmission and distribution losses accompanied with low power factors. The activities in this group therefore concentrate on real time monitoring and control of power systems, power systems reliability and production costing analysis, energy conservation in power distribution and utilization systems and reactive power compensation. The group also works on devising, testing, field trials and subsequent industrialization of developed equipment
The Internal Combustion Engine laboratory possesses various facilities for basic engine testing and for analyzing the exhaust for measuring CO, HC and NOx emissions. Using various alternative fuels like ethanol, methanol, vegetable oils, hydrogen and biogas, the group undertakes engine design modifications to achieve higher efficiencies and low CO, PM and NOx emissions. The IC engines group has been involved in various National mission projects like developing a fuel injection system for gasdine fueled engines, a four stroke engine for two wheelers and plasma based nitride coating on vulnerable engine parts like cylinder or pistons. The activities in the area of IC engines also cover computer aided design in agriculture, power generation and transportation sectors.
One of the main aims of buildings is to provide internal environment where one can have visual as well as thermal comfort. This is partly provided by an energy efficient building design and/or by providing energy efficient end use devices. By using sophisticated computer modelling, the building group in the Centre assists the architects to arrive at an optimum design to achieve better day lighting and minimize the air conditioning load. Additionally, the group can also undertake the design and fabrication of building automation systems to reduce energy related operating costs.
The Centre can undertake extensive energy audits to identify (i) where and in what form the energy is being used in an organization/industry,
(ii) intensity of energy use and
(iii) energy conserving opportunities.
The audit report presented to the organization also contains detailed techno-economic evaluation of each of the energy conserving opportunities and priority wise recommendations for implementation. The technology improvement for achieving better energy efficiencies is also prioritized out through continuous R&D activities in the relevant areas.
