چکیده
As an efficient energy conversion technology, the organic Rankine cycle (ORC) has been widely applied in medium- and low-grade heat sources. In order to explore experimental performance of ORC reveal effects operation parameters, setup was built R123 selected as working fluid. experiments, source temperature well mass flow rates fluid cooling water were controlled. Under design conditions, net work efficiency can, respectively, reach up 0.55 kW 8.7%. for influences key with increase from 130 °C 160 °C, involved a small increase, while increases 0.44 kW, greatly 6.71% 8.72% at rate 25 g/s. water, it similar impact on performances. The difference is that effect relatively smaller. At g/s, when 0.68 kg/s 0.83 kg/s, varies 0.46 range 7.41~9.4%. Furthermore, except efficiency, all performances are proportional test range, among different less than 0.7%.

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...
