Predictive Controller

Direct steam generation has distinct cost advantages over alternative methods for producing superheated steam from a solar collector system. We present results from a model predictive controller for a solar steam generator that is configured as a once through to superheat process using direct steam generation. The solar collector system modeled uses a linear Fresnel reflector field with a multi-tube receiver. The model predictive controller uses step response models that are developed offline using a dynamic simulation. The model predictive controller incorporates a feedforward signal based on absorbed solar power. Performance of the controller has been demonstrated at the Kimberlina Solar Power Station near Bakersfield, California. The results show the feasibility of a controller for a solar direct steam generation system that provides stable superheated steam temperature and pressure conditions through weather events.
