In order to solve the shortcomings of single air source heat pump, solar pump and double one electric multi-stage dual a integrated is designed. The heating capacity COP same under three different operating conditions were simulated, simulation results compared analyzed. show that system are higher than those system. With continuous decrease outdoor temperature, advantages wind tunnel hybrid mo...

The boiler drum level control unit is one of the main parameter in the thermal power station. Currently the boiler drum parameters are monitored only by using MATLAB software. There is no automatic control available. In the proposed system the boiler drum parameters such as temperature level, pressure level, water level and Droplet identifier are measured and controlled by using embedded proces...

Background: In this study, measurement of indoor radon and its progeny levels was carried out in Gas Turbine Power Station in Haryana ( India ), where natural gas is used as fuel. For comparison, the results of a study carried out in thermal power plant in Haryana are also presented. Radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

A design has been developed for a rotary fluid coupling to transfer coolant fluids (primarily anhydrous ammonia) across rotating joints of the Space Station. Development testing using three conceptual designs yielded data which were used to establish the design of a multipass fluid coupling capable of handling three fluid circuits. In addition, a mechanism to support the fluid coupling and allo...

High altitude platform station (HAPS) is a wireless repeater in the air. It can play a dominant role in observations, remote sensing and communication. The structure and composition of formation of HAPS are studied in this paper. The performance of the wireless communication link are researched. The simulation results shows that the power of receiver is proportional to the received power and th...

s: df/dt relays are used in the power industry to rescue systems facing extreme disturbances to avoid system collapse. Traditionally, many computations are repeated to seek the proper power system settings such that the df/dt relay provides the desired good performance for selected scenarios. In this paper a case study of tripping of Farakka Super Thermal Power Station and proposed adaptive df/...
