Abstract
The invention relates to a method for controlling a thermal cyclic process, in particular an Organic Rankine Cycle (ORC), which is operated with a working medium in conjunction with a dynamic heat source, whereby the method comprises the following steps: (a) determination of a setpoint value of a process variable of the thermal cyclic process from a value of an input parameter or respective values of a plurality of input parameters of the thermal cyclic process; (b) control of the thermal cyclic process with the determined setpoint value of the process variable as a target variable of the control; and (c) repeated execution of steps (a) and (b) when at least one value of the input parameters changes.
Claims12
A method for controlling a thermal Organic Rankine Cycle (ORC) process, which is operated with a working medium in conjunction with a dynamic heat source, comprising:
- (a) determination of a setpoint value of a process variable of the thermal cyclic process from a value of an input parameter or respective values of a plurality of input parameters of the thermal cyclic process;
- (b) control of the thermal cyclic process with the determined setpoint value of the process variable as a target variable of the control;
- and
- (c) repeated execution of steps (a) and (b) when at least one value of the input parameters changes,
- wherein the determination of the setpoint value of the process variable of the thermal cyclic process comprises a calculation of the setpoint value from a predetermined function into which the input parameters are input as variables.
A computer program product comprising at least one non-transitory computer-readable medium with instructions that can be executed by a computer and that are for carrying out a method for controlling an Organic Rankine Cycle (ORC) process during operation on a computer, the instructions when executed by the computer cause the computer to:
- (a) determine a setpoint value of a process variable of the thermal cyclic process from a value of an input parameter or respective values of a plurality of input parameters of the thermal cyclic process;
- (b) control of the thermal cyclic process with the determined setpoint value of the process variable as a target variable of the control;
- and
- (c) repeat execution of steps (a) and (b) when at least one value of the input parameters changes,
- wherein the determination of the setpoint value of the process variable of the thermal cyclic process comprises a calculation of the setpoint value from a predetermined function into which the input parameters are input as variables.
