【正文】 bility to formulate a range of alternative problem solutions, and puter literacy specific to electromechanical and electronic systems is a plus. Survey instrument is not included in this paper. Industrial advisory board members of the Industrial Technology Department during the academic year of 20022003 have also indicated the necessity of data acquisition skills for their prospective employees. Thus, this LabView? instrumentation system will help the students to develop skills in data acquisition, and analysis.Computer Aided Instrumentation and Interface of the WindSolar Power SystemThe objective is to transform the six experimental variables: DC voltage, DC current, AC voltage, AC current, wind speed, and wind direction into a form readable by the puter, display and store the results in real time . The DC power and AC power need to be calculated and monitored through the other predetermined variables using LabView’s programming capabilities. The signal conditioning hardware to condition and isolate the voltage and wind information signals before being connected to the DAQ board will play a significant role in the virtual instrumentation of the overall system. The instrumentation phase of the windsolar power station includes the following hardware: One CR411010 True RMS AC Current Transducer and one CR5210 50 DC HallEffect Current Transducer from CR Magnetics, voltage and current divider and scaling circuits, one wind monitoring device called anemometer, a LabView 6i Professional Development System for Windows NT/98, one PCI6071E I/O Board, one NIDAQ Driver Software, one SH 100100 Shielded Cable, SCSIII Connectors, one SCB100 Shielded Connector Block, one isolation amplifier circuit, and a PC. A DMM and an oscilloscope to check the analog signals would also be very useful. Figure 2 illustrates a block diagram of the overall instrumentation system. DC voltage generated by four solar panels and one wind generator is applied to the battery bank.A Young 05103V Anemometer provides two voltage signals corresponding to wind speed and wind direction values. These wind signals are fed to AD21OAN Isolation Amplifiers and the output is applied to National Instrument’s SCB100 Data Acquisition Board (DAQ). Two voltage signals, one from battery output and one from inverter output are also appli
