摘要： A pressure sensor measures an organic Rankine cycle (ORC) working fluid pressure in front of a radial inflow turbine, while a temperature sensor measures an ORC working fluid temperature in front of the radial inflow turbine. A controller responsive to algorithmic software determines a superheated temperature of the working fluid in front of the radial inflow turbine based on the measured working fluid pressure and the measured working fluid temperature. The controller then manipulates the speed of a working fluid pump, the pitch of turbine variable inlet guide vanes when present, and combinations thereof, in response to the determined superheated temperature to maintain the superheated temperature of the ORC working fluid in front of the radial inflow turbine close to a predefined set point. The superheated temperature can thus be maintained in the absence of sensors other than pressure and temperature sensors.

摘要： A system and method are provided for using the thermal mass of an ORC, the working fluid, the oil loop, the cooling fluid loop and all components, to provide additional transient power to an electrical grid. A pre-heater transfers heat from the cooling fluid to a low temperature (LT) ORC loop working fluid. A LT ORC loop expander generates transient power to support stabilization of the electrical grid. A heat exchanger transfers heat from the thermal oil to a high temperature (HT) ORC loop working fluid. A HT ORC loop expander generates transient power to support stabilization of the electrical grid.
