OSTI ID:6500216
The object was to develop a generic dynamic simulator/analyzer for binary-cycle geothermal power plants for use on today's personal computers. The simulator/analyzer, as developed, can be used for (1) engineering analyses of static/dynamic performance and design trade-offs; (2) operator training and operating procedure evaluation; and (3) binary cycle technology demonstration. The simulator/analyzer consists of a set of ordinary non-linear differential equations that are programmed in a simulation language format and solved on an IBM-PC-AT. The equations are driven in an interactive mode by inputs from the PC keyboard and responses of plant temperatures, pressures, flows, etc., can be observed on a real-time color display that replicates a control room interface. Simulation predictions have been validated by comparisons with actual transient and steady state data taken from the Heber Binary Project, a 46.6 MWe binary-cycle demonstration power plant in operation in southern California. The simulation is accurate to within the uncertainty of the plant's process sensors. During this plant's later phases of construction, startup and operation, the simulator/analyzer is being used to: develop tuning constants for the Honeywell TDC-2000 control system, confirm failure/safety analyses study results, and support analyses of major operating events. It represents an adaptable tool for utilities and others involved in developing geothermal power generation facilities.
