TSI-PTSS 5015 Additional Power Generation Module

This unit has been specifically designed to extend the capability of the power training systems simulator. It provides an additional power generation plant that includes a step-up transformer and an HV output busbar system.

The workstation incorporates a machine mounting bed where different DC and AC motors can be connected to a fixed 3-Phase Generator.

An Automatic circuit breaker main switch provides overall power to the module. It also includes an emergency stop button that will remove all mains power to the module when pressed. All circuit interconnections can be made using 4mm safety leads and sockets.

The outputs from the electronic variable motor drive can be connected to the AC drive motor to allow for changes in the speed and torque of the fixed synchronous machine (Generator). This is a fully programmable control and it can be used with a range of AC motors.

The unit is supplied as standard with the following specification AC Motor:
  • V = 220/380V
  • F = 60Hz
  • Nominal maximum speed: 3,600 RPM approx.
  • Rated power: P = 1.5 KW
  • I = 7/4 A approx.
A separate variable DC excitation control is provided to allow for changes in the voltage and reactive power of the 3-Phase Generator.

The generator has the following characteristics:
  • Rated power: P = 1KW

  • Nominal maximum speed: 3.600 RPM

  • Vin = 220/380V

  • f = 60 Hz when functioning as motor

  • Vout = 220/380V

  • f = 60 Hz when functioning as generator

  • Iout = 2.8/1.6 A approx.

The output from the generator can be connected to a step-up transformer. This has an apparent power of 1,000 VA. The primary voltage for DELTA connection is 150 V, for STAR connection it is 260 V. The secondary voltages for DELTA connection are 69 -127 V, for STAR connection they are 120 - 220 V.

The additional generator unit has two types of parallel synchronisation: Manual and Automatic.

This will allow manual selection of parallel synchronisation between the output of the 3-phase generator and the power training systems simulator systems infinite power grid using a voltmeter, zero-voltmeter and a synchroscope.

This consist of three lamps that make up a synchroscope. The lamps flash with a frequency of a few Hz (the difference between the frequency of the network and that of the generator). When the lamps go dark it gives a positive indication that the generator is synchronised with the mains.

The voltmeter Zero Volmeter also displays the voltage reading across the lamps and confirms the synchronized voltages before the user attempts manual closing of the paralleling switch. This system has a circuit that will automatically lock in and protect the synchronous generator.

This mode is designed to automatically adjust the speed, voltage and phase shifting of the rotating generator in order to carryout automatic management of synchronisation and paralleling between the generator and the mains supply.

The user can make adjustment to the parameters of the controller’s PID control loops, using the control panel interface.

After successful parallel synchronization it will be possible to share the load between the mains and the synchronous generator.

An outgoing HV bus system is used to connect the additional power generation simulator module to the other simulator units. The unit has two circuit breakers, one for the protection of the medium-voltage windings of the transformer and one for the protection of the high-voltage windings of the transformer.

The module is equipped with two digital multifunction 3-phase instruments for measuring voltage, current, active power, reactive power and harmonics. These have both numerical and graphical display options.

The unit is supplied in a steel mobile cabinet with a durable powder coated finish with two lockable doors on the storage area. It includes all power connection points, cables and accessories.

Dimensions: H:1,970mm x W:1,000mm x D:750mm - with 100mm width work surface.
