PST2210 Power Plant Module

Description

General

PST2210 Power Plant Module 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 PST2210-module has also synchronization and phasing devices, digital bar-graphs for voltage and frequency, step-up transformer, current and voltage transformers, relay protections, A and B bus bars with two outgoing lines.

Operation of breakers and isolators is controlled and interlocked by PLC’s for safe operation by students. The step-up transformers can be operated individually and all terminals are available from the front panel providing access to delta and star-connected windings.

Access to the generator windings are provided on the front panel.

Protection relay current transformer windings are accessable on the front panel via external connectors. Possibility for floating, impedance and direct-earthing of transformer and generator is available on front panel.

PST2210 contains a fault simulator with the ability to simulate variable short circuit and earth faults.

The module includes 4, 8-pole Transfer Blocks for easy signal transfer between different compatible modules.

Possible earthing methods:

1. a) Solid earth
2. b) Resistive earth
3. b) Floating earth
