D-AVR Advantages

  • Realize 5msec sampling time with 32-bit RISC processor.
  • Better space factor in a cubicle by downsizing to be an integrated unit.
  • Dual system configuration using duplex cable connections of 2 units.
  • All interfaces is cable and installed front or bottom side. All connector has different shape for preventing from wrong connection.

High reliability・High functionality・High-performance control

  • High speed computation using a 32-bit high-speed RISC processor.
  • Superior control accuracy using a 16-bit analog-digital conversion.
  • ⊿P type and⊿f type PSS are equipped as power grid stabilizing functions. Applicable to ⊿ω system PSS with an optional card.
  • Reboot function permits automatic recover from a transient fault.

Operation・Maintenance

  • Maintenance tool can monitor, operate, parameter set and trend graph display at fault condition.
  • Allows quick detection of faulty positions with LED display, maintenance tool alarm system and CPU fault information display.
  • High density functions are realized by using box-type module and functional software.
  • When dual system is consisted, On-line replacing is applicable. Moreover interface connectors are selected different shape to prevent wrong connection.
  • High space efficiency and easier maintenance with high-density and downsizing by use of functional software.
  • In order to support periodical inspections, Software and a maintenance tool for tests are provided.
