Figure 38: Overview of reporting functionality (PMUREPORT)
The TRM modules are individually AC-calibrated in the factory. The calibration data is
stored in the prepared area of the TRM EEProm. The pre-processor block is extended with
calibration compensation and a new angle reference method based on timestamps. The
AI3P output of the preprocessor block is used to provide the required information for each
respective PMUREPORT phasor channel. More information about preprocessor block is
available in the section Signal matrix for analog inputs SMAI.
6.2.3.1 Frequency reporting
By using patented algorithm the IED can track the power system frequency in quite wide
range from 9 Hz to 95 Hz. In order to do that, the three-phase voltage signal shall be
connected to the IED. Then IED can adapt its filtering algorithm in order to properly
measure phasors of all current and voltage signals connected to the IED. This feature is
essential for proper operation of the PMUREPORT function or for protection during
generator start-up and shut-down procedure.
