Real-time digital data-acquisition system for determining load characteristics. Volume 2: Operating, programming and maintenance instructions
Abstract
The design and construction of a Real-Time Digital Data Acquisition System (RTDDAS) to be used in substations for on-site recording and preprocessing load response data were included. The gathered data can be partially processed on site to compute the apparent, active and reactive powers, voltage and current rms values, and instantaneous values of phase voltages and currents. On-site processing capability is provided for rapid monitoring of the field data to ensure that the test setup is suitable. Production analysis of field data is accomplished off-line on a central computer from data recorded on a dual-density (800/1600) magnetic tape which is IBM-compatible. Parallel channels of data can be recorded at a variable rate from 480 to 9000 samples per second per channel. The RTDDAS is housed in a 9.1 m (30-ft) trailer which is shielded from electromagnetic interference and protected by isolators from switching surges. The test must sometimes be performed. Information pertaining to the installation, software operation, and maintenance is presented.
