PST2212 Additional Power Generator



PST2212 Additional Power Generator is a Power Plant with 2.2 kW 3-phase AC Induction Motor and Field Oriented Programmable Drive for simulating a turbine with different characteristics as:

  • Steam turbine (nuclear, geothermal, fossil)
  • Hydro-electric turbine
  • Small diesel motor

The three-phase 1.2 kVA synchronous generator has electrical parameters similar to real units.

Manual or automatic control both for the frequency (=active power) and the voltage (=reactive power). One-line mimic diagrams together with power breakers and isolators and groups of digital instruments arranged in the same way as in real plants.

The PST2212-module has step-up transformer, current and voltage transformers, relay protections for generator and transformer, A and B bus bars.

Operation of breakers and isolators is controlled and

interlocked by PLC’s for safe operation by students.

The step-up transformers are operated individually and all windings can be available via terminals on the front panel.

All necessary current transformers and voltage transformers are included and the necessary windings accessable via terminals on the front panel.

Possible earthing methods:

  1. Solid earth
  2. Resistive earth
  3. Floating earth
