A two-phase thermodynamic power system includes a capillary device, vapor accumulator, superheater, an inline turbine, a condenser, a liquid pump and a liquid preheater for generating output power as a generator. The capillary device, such as a loop heat pipe or a capillary pumped loop, is coupled to a vapor accumulator, superheater, the inline turbine for generating output power for power generation, liquid pump and liquid preheater. The capillary device receives input heat that is used to change phase of liquid received from the liquid preheater, liquid pump and condenser into vapor for extra heating in the superheater used to then drive the turbine. The power system is well suited for space applications using a radioisotope, active nuclear or solar heat source. The system can use waste heat from various dynamic or static power systems as a heat source and waste heat from spacecraft components such as electronics as a heat source. These heat sources can be used separately or in any combination. The power system can be combined with thermal energy storage devices when operated with heat sources that are not steady state. Heat sources are useful for driving the capillary wick, superheater and liquid preheater for increased power efficiency and long lifetime operation. The power system is well suited for space receiving heat from a heat source to produce useful mechanical energy. A superheater in combination with a liquid pump and preheater are implemented for use with the evaporator for improved thermal efficiency while operating at maximum cycle temperatures well below other available power conversion cycles.

The invention relates to a method for identifying a delay-susceptible control path in the control of a steam generator, and a device constructed for carrying out the method. A model structure of the steam generator is specified, consisting of an unknown time-variable Nth-order delay element and a known integrator. Also used for the identification are measurements of the fuel mass flow, the turbine steam mass flow, and the live steam pressure which arises in the steam accumulator behind the steam generator after the removal of the turbine steam mass flow. Using these online measurements and the model structure, the live steam mass flow at the output of the steam generator is derived by calculation. In this way, the input value and the output value of the Nth-order delay element (VZN) are determined in such a way that, using an estimation method, the parameters of a continuous transmission function of the Nth-order delay element (VZN) are also determined online. The estimated parameters are then converted into the time constants of a delay element with N independent time constants. In a following step, the relevant time constant for the delay element of the specified model structure is determined by comparison of the N independent time constants.
