The design and implementation of LabVIEW-aided power system SCADA (Supervisory Control And Data Acquisition) for industrial applications is presented in this thesis. The system includes some sensors¡Bcontrol hardware, and two fore-microprocessors; and it runs in the environment of popular windows by personal computer, using LabVIEW between human and machine. The mainframe computer can get the electrical power parameters (such as voltage¡Bcurrent and power factor )from the fore-microprocessor via RS-485 communication interface. All of the power parameters and control signals are transmitted upon the network, so it can also command the remote controllers to detect the status and control the switching gear of the remote equipments. These data can be recorded and stored simultaneously in the LabVIEW environment and displayed on the screen. The design accomplishes function of signal acquisition and data transmission features low cost¡Bhigh stability, with remote controller, and easy expansion. It can mange and control the conventional household or industrial electric equipment, to achieve the goal of energy conservation.
