Control System Training Simulators - Transmission and Distribution Simulator

TDSIM is a real time training tool designed to train students to handle real life challenges faced during actual power distribution emergency conditions.

Wireless SCANET SCADA for Industrial Automation - Transmission and Distribution Simulator

Key Features

  • Use of load flow analysis for calculation of current, voltage and power flowing throughout the network.
  • Use of actual transmission and distribution data to provide training on a real life System.
  • Simple and intuitive trainee interface.
  • Facility to create various faults and a step by step procedure to clear them.
  • Any situation can be saved as a snap shot which can be loaded at any later time.
  • Fast Forward facility for faster completion of time consuming operations.

Switch Yard Operations

Students are trained with operating procedures of the following devices which can be operated only from the switchyard:

  • Isolators
  • Earth switch
  • Neutral Link

Control Room Operations

Students are trained on the proper operating sequence for feeders and transformers using corresponding control panels.

Load Management

Students are trained on the critical aspects of load management that involves multiple switching operations to meet the desired load relief during a power outage.

Battery Charger Operation

Students are introduced to the battery charge operations using boost mode and float mode through a battery charger panel.

Fault Rectification

The simulator provides in-depth training on the various fault conditions that normally occur in any T & D system. Students have to select step by step the various checks that they would perform in order to rectify the fault.


With the help of this control strategy, trainees can easily grasp the effect of interaction between processes. With the help of relative gain array design, they can decouple the interacting control loops.

Cable Fault Isolation

Students are introduced to the method of locating a cable fault. Once it is located, they are required to restore power by appropriate switching operations.

Tap Change Operation

Tap change for any transformer can be carried out by selection of the appropriate transformer panel and its tap change sub-panel. This panel allows step by step increase or decrease in the tap position.

Overhead Network Operations

Students are imparted training on the operation of the following overhead lines:

  • Jumpers
  • Drop out fuses
  • Removal of node from the ring

Modes of Operation

The following modes of operation are supported:

  • FREEZE MODE: In this mode trainee can take a snapshot of any difficult situation which can be reloaded at any later time.
  • FAST FORWARD MODE: This mode allows faster completion of time consuming operations.
  • INSTRUCTOR MODE: This mode allows instructor to define new exercises and download them to the students.
