| 101 | System for economic unit load distribution during process load transition | US942947 | 1986-12-15 | US4745758A | 1988-05-24 | Richard E. Putman; Katherine A. Gundersen |
| In a plant including a multiplicity of energy conversion units which together supply load upon demand to a given process through a common junction, a system is included to economically optimize the load distribution among the multiple units dynamically during the transition of process load demand from one state to another such that when the process load supply reaches the other process demand state, the energy conversion units are substantially in their economically optimum individual load generating states. Typical unit load dispatching plants may include a boiler house in which a multiplicity of boilers are coupled to a common header for supplying stream flow to the particular process, a power turbogeneration system in which a multiplicity of turbogenerating units supply power to a power system network through a common bus and a heat exchange industrial process in which a multiplicity of power-driven compressors are used together with corresponding chiller units for maintaining the temperature of a common coolant under varying coolant flow demand conditions. | ||||||

| Inplant sensors in the boiler and turbine units sense present values of a number of physical parameters designated process variables, and of certain control variables. Set points are developed, and deviations therefrom of the control and process variables are calculated. Utilizing a mathematical model, state variable deviations are estimated and translated into corresponding physical parameter estimates, which are used to evaluate model inaccuracy. State variable and model error estimates are translated into desired control deviations, which in turn are combined with fed forward values of the control variable set points. The combined control terms actuate controllers in the boiler and turbine units. | ||||||

| Method and system for adjusting a measured reheat outlet steam temperature (“RPV”) to approximate a reheat outlet steam temperature setpoint (“RSP”) in a boiler. An RPV is compared to an RSP. If the RPV is less than the RSP and a position of a fuel nozzle tilt (“TILTPV”) is below a high limit of the fuel nozzle tilt (“TILTHIGH”), the TILTPV is increased while a flow rate of a secondary flue gas recirculation (“SFGRPV”) is kept constant. If the RPV is less than the RSP and the TILTPV is at the TILTHIGH, the SFGRPV is increased. If the RPV is greater than the RSP and the SFGRPV is greater than a low limit of flow rate of the SFGR (“SFGRLOW”), the SFGRPV is decreased, while the TILTPV is kept constant. If the RPV is greater than the RSP and the SFGRPV is at the SFGRLOW, the TILTPV is decreased. | ||||||
