Development of a Low Temperature Geothermal Organic Rankine Cycle Standard
Low temperature geothermal systems are an abundant energy resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle (ORC) is the standard process for low temperature energy conversion with commercial ORCs utilizing temperatures as low as 90°C, with one site at Chena, Alaska (discussed below) utilizing temperatures as low as 74°C. The a...
متن کاملAdaptive PI Control of an Organic Rankine Cycle Power Plant
In this paper a PI based adaptive control system is developed to control an organic Rankine cycle power plant. In particular, the control of the turbine speed during the transient between the normal operation mode of the system (connected to the grid) and the islandmode (connected to a stand-alone load) is of main concern. A control algorithm suitable for the implementation on a programmable lo...
متن کاملAnalysis of Zeotropic Mixture in a Geothermal Organic Rankine Cycle Power Plant with an Air-cooled Condenser
The purpose of this research is to investigate a zeotropic working fluid mixture in terms of its performance in an organic Rankine cycle (ORC) and the heat transfer characteristics in an air-cooled condenser (ACC). The motivation of this study is that it is well known that the use of a mixture improves the efficiency of an ORC system. However, the behaviour of the mixture in the condensers is n...
متن کاملComparative investigation of working fluids for an organic Rankine cycle with geothermal water
In this paper, the thermodynamic investigation on the use of geothermal water (130 ◦C as maximum) for power generation through a basic Rankine has been presented together with obtained main results. Six typical organic working fluids (i.e., R245fa, R141b, R290, R600, R152a, and 134a) were studied with modifying the input pressure and temperature to the turbine. The results show that there are n...
متن کاملEffect of Ambient Temperature on the Performance of a Combined Cycle Power Plant
The aim of the present paper is to examine the effect of ambient temperature on the performance of a combined cycle power plant. For this work, the combined cycle plant chosen is NTPC (National Thermal Power Corporation) Dadri, India where a gas unit of 817 MW is installed. The effect of ambient temperature on combined cycle efficiency, gas turbine cycle efficiency, exergy destruction in differ...
