To meet peaking power demands the E.W. Brown Station, owned and operated by Kentucky Utilities Company, was extended by two GT24 gas turbines. The project had to meet a 9-month engineering, construction and commissioning schedule. The conceptual design is based on ABB ALSTOM POWER’S reference plant design for combined cycle application. It was adjusted to the requirements of a simple cycle operation. Special plant features such as evaporative cooling of the inlet air, system design of the evaporative cooling system, performance and experience will be discussed in detail. The plant has an aggressive running and starting reliability goal; the approach to meet the required plant reliability will be discussed below. The initial operational feedback will be addressed as well as an outlook on how to meet all project goals.

As one of the most promising solutions to the reduction of fossil fuel consumption and greenhouse gas emissions, the use of solar energy for building space heating and cooling recently has again aroused researcher’s interest with the growing awareness of the global warming and other environmental problems. Compared to the relatively mature solar heating, solar cooling technology remains at the demonstration and testing stage due to its complicated system characteristics, both in concept and construction. Among many solar cooling technologies, solar absorption technology is the most suitable technology for the solar cooling. The major barriers to widespread deployment of the solar absorption cooling are its high first cost, the lack of guidelines of its design and operation, and the relative low system performance due to the lack of the system integration. The paper provides detailed information of an on-going solar heating and cooling research project conducted at Purdue University in West Lafayette, Indiana. The aim of the research is to develop a cost-effective and integrated solar heating and cooling system. The solar thermal system primarily includes a 45kW single effect absorption chiller, evacuated tube solar collectors (ET), and heat storage tanks. The system has been designed based upon scientific principles and engineering fundamentals. It has been analyzed and optimized to achieve the high cost-effectiveness and the high system efficiency through the system performance simulation in Transient Energy System Simulation (TRNSYS) program.

A large solar hot water system can be utilized to provide driving energy for heating system, heat-driven cooling system, as well as to provide hot water. This research addresses the effects of the storage tank design parameters on the performance of a large-scale solar hot water system with a horizontal storage tank. Most literatures only considered the stratification performance of the thermal storage tank itself instead of considering the overall system performance. Also, there is lack of experimental research data available for the design purpose. Therefore, this study employs a numerical simulation technique to study the design parameters effect of a horizontal thermal storage tank on the performance of a large-scale solar hot water system. In this study, the ANSYS-CFX program is employed to calculate the flow and temperature distributions inside horizontal thermal storage tank. Then the inlets and outlets of the tank are combined with the TRNSYS program to simulate the entire system performance under the weather of three representative cities of Taiwan, (Taipei, Taichung and, Kaohsiung). The results of the present study indicate that the vertical stratification baffles in the tank have important effects on system performance improvement. Quantitative increase of solar fraction of the total load is obtained. The comparison with the system with vertical storage tank is provided. The results of the present study can provide important reference for the large solar hot water system design in improving system efficiency.

According to the characteristics of Fast Speed Mirror, the paper discusses that, in a FSM composite axis control system, the mechanism of the servo control, the main system performance, the speed loop of subsystem and effects of automatic zero locking system. Combined with traditional methods, a new structure of axial subsystem is proposed, to improve the rapid high-precision tracking technique. From theory to experimental model, the paper made a detailed analysis.
