01 / 03High-fidelity process simulation
A mistake on the simulator costs nothing.
Our operator training simulators reproduce the dynamics of your plant — the same trends, the same interlocks, the same alarms — so operators build judgement on a model instead of on live equipment.
Slide 2 of 3
02 / 03Startup, shutdown and emergency drills
Train for the shift nobody plans for.
Cold start, hot restart, trip recovery, runaway exotherm, loss of instrument air. Instructors insert malfunctions live, adjust severity, backtrack a minute at a time, and score the response afterwards.

03 / 03India’s first process simulation company
Four decades of models, built in-house.
We installed India’s first process simulator in 1983 and delivered the country’s first digital computer simulator in 1985. Every model since has been written by our own engineers.

§ 01Who we are
Simulation is not a sideline for us. It is the whole business.
Tri-Angle Simulation Pvt. Ltd. was founded in Mumbai in 1979 as India’s first process simulation company. For more than four decades we have built one thing: software and hardware that lets engineers and operators practise running a plant before they ever touch one.
That work has taken us into refineries, thermal and hydro power stations, fertiliser complexes, pulp and paper mills and more than thirty engineering institutions. The front-end and back-end simulation libraries behind all of it are our own — developed in-house, tuned against real operating data, and maintained by the same team that wrote them.

§ 02What we build
Six things we do, and nothing we don’t.
Simulation is the entire business. Every line below is work we have delivered and support today.
Operator Training Simulators
Dynamic plant models driving an emulated DCS or a one-to-one panel replica, with an instructor station that controls every session.
Learn moreDynamic model development
Custom first-principles models tuned to your equipment data, valve characteristics and five sets of operating data across the load range.
Learn moreLab-scale process trainers
Working PC-based control rigs — level, flow, cascade, pH, pressure, distillation, reactors — for teaching laboratories and training centres.
Learn moreHardware-in-loop testbeds
Real transmitters, controllers and final elements wired to a live mathematical model, for control-system testing and research platforms.
Learn moreOperator & student training
On-site and classroom programmes running from three days to a week, delivered at plants, training centres and engineering colleges.
Learn moreCommissioning & support
Site acceptance testing, model tuning against plant data, handover training, and long-term maintenance of the models we deliver.

§ 03Product spotlight
One instructor station. Every operator console. Your plant’s dynamics underneath.
The suite ships in two architectures. Uni-Op puts the instructor and the operator at the same console for classroom and academic use. Multi-Op runs a model server with independent or shared operator action consoles, so a crew learns to co-ordinate exactly as they would in a real DCS control room.

DCS emulation and direct connect
Emulations for Honeywell TDC-3000, ABB, Yokogawa and generic DCS, with look-alike keyboards, touch screens and DCS-style cabinets.
- 04
Scenario creation
Pre-programmed malfunction sequences let an instructor build a repeatable drill once and run it with every shift.
- 05
Performance monitoring
Trainee and instructor actions are logged, sorted and scored, with trend history tied back to the initial condition the exercise started from.
- 06
Remote and instructor-less training
Remote operation and self-paced sessions with context-sensitive online help, for training that continues between instructor-led courses.
- 07
3D / VR field operationsIn development
Field-operator training in a walkable plant model, so board and field crews can rehearse a procedure together. Currently in development.

§ 06Why choose us
Four decades is not the argument. It is the evidence.
What matters is that the models still match the plants, and that the people who wrote them still answer the phone.

In-house development centre
Our simulation libraries, model builder and graphics utilities were all written here. When a model needs to change, the people who wrote it make the change.
Models tuned to your plant
We work from your equipment specifications, valve and pump characteristics, component property data and five sets of operating data across the load range.
Engineering and domain depth
Process, control, electrical and software engineers who have commissioned simulators inside working refineries and power stations, not only in a lab.
Support that outlasts the project
Site acceptance testing, handover training, warranty support and long-term maintenance — some of our installations have been in service for over twenty years.

Power & EnergyChandrapur, Maharashtra, India2008
500 MW unit simulator with emulated ABB DCS
MAHAGENCO — Chandrapur Super Thermal Power Station
- Challenge
- Chandrapur’s Unit 7 is a 500 MW set. Crews had to be brought up to competence on cold start, load ramping and trip recovery without taking a large unit off the bar to practise on.
- Solution
- A high-fidelity simulator built around Unit 7, with the ABB Procontrol P13 DCS emulated so the operator sees the same faceplates, graphics and alarm behaviour as on the real board. Boiler, turbine, generator, electrical system and balance of plant are all modelled, including FSSS, ATRS, co-ordinated master control and the turbine stress evaluator.
Result
Installed, commissioned and customised on site at CSTPS. The unit’s operating crews train on startup, shutdown and emergency sequences on the simulator rather than on the running set.
Refining & PetrochemicalsBina, Madhya Pradesh, India2009 – 2013
Refinery process training simulator for a new-build refinery
Bharat Oman Refineries Limited
- Challenge
- A greenfield refinery needed trained board operators before the units existed to train them on — the classic commissioning problem, where the first people to run a unit have never run that unit.
- Solution
- Supply, installation and commissioning of a process training simulator covering the crude and vacuum distillation units, the sulphur recovery unit and the fluidised catalytic cracking unit, followed by instructor-led training courses conducted on site at Bina.
Result
Operators reached the control room having already run the units through normal operation, upsets and shutdown on the model. Training was completed on site in 2013.
Research & AcademicMumbai, Maharashtra, IndiaRecent
Hardware-in-loop testbed for a 500 MW thermal unit
Veermata Jijabai Technological Institute
- Challenge
- Control research and teaching need real instruments and controllers in the loop. A pure software model does not expose students to signal conditioning, wiring faults or controller tuning against real I/O.
- Solution
- A hardware-in-loop testbed in which physical plant devices exchange signals with a mathematical model of a 500 MW thermal unit running in real time. The model computes the process; the hardware sees it as a plant.
Result
A working research and teaching platform where control strategies can be tested against plant dynamics with real devices in the loop. A companion 40 MW hydro testbed was delivered to the Central University of Jammu.
