摘要：In this project, PQ analyzer is developed which depicts the detection and classification of short
and long duration disturbances in power system. These disturbances comprising of sag, swell,
interruption, undervoltage, and overvoltage. All these disturbances are analyzed by
uninterruptedly monitoring of power system. This paper outlines the start time, end time,
magnitude and waveform of disturbances. These detected disturbances are classified on the basis
of their respective characteristics. The perceptions and classifications are accomplished by using
Advanced Digital Signal Processor (ADSP-21369). The statistics of disturbance are stored
precisely and accurately. The prototype is configured with the LabVIEW to receive and store all
the data which is sent by the processor via UART interface (RS-232 protocol).
