Thermal power plant simulator
For safe, efficient and economical thermal power plant operation
|
Typical training senario from our thermal power plant simulator.
|
There are a significant numbers of thermal power plants around the world and
new plants based on coal firing are put into operation almost weekly. This creates
an increasing need for trained thermal power plant personnel. We offer a thermal
power plant simulator that fulfils these training requirements.
Our simulator is suited for
The thermal power plant simulator model is ideally suited for both the training
of newly-hired employees and refresher courses of personnel with earlier experience.
The main purpose of the Thermal Power Plant simulator is to train and assess operators
in the operation of Distributed Control Systems (DCS) and in plant operation, including
training in plant start-up and shut-down, emergency situations and safety procedures.
Based on a real plant

|
We acknowledge that thermal power plant training must be based upon real installations,
therefore our thermal power plant simulator is modelled on the latest block (4)
of a thermal power plant in Vesteraas, Sweden. The plant is fuelled with oil and
coal. Oil is mainly for start-ups and safety support when on pulverized coal operation.
At pure condensation operation the block produces a net electrical output of 250MW
(190 MW for coal). The utility heating hot water effect at back pressure operation
is 350MW with oil and 260 MW for coal.
Utilising real thermal power plant operation as the basis for simulation provides
our customers with a strong foundation on which to base the training of their personnel,
ensuring that their operational procedures and practices will enhance the plant
economical efficiency and safety measures.

The main purpose of the Thermal Power Plant simulator is to train and assess
operators in general plant operation, including training in plant start-up and shut-down,
supervision, monitoring and control during normal, emergency situations and in safety
procedures.
In addition the simulator can be used as a powerful tool for engineers and plant
management to verify process design and control strategies prior to start-up of
a plant as well as investigation and testing of operational problems that are normally
not allowable under real plant normal operating conditions.
Our simulator is highly flexible and can be used in a number of different ways
to suit the changing needs of the thermal power plant. To date; some of these uses
are:
- Test and tune control loops before implementing on a real system
- Test and modify logic in a dynamic environment
- Familiarise commissioning engineers with the plant and process dynamics
- Allow commissioning engineers to test out different start-up procedures
- Modify control and logic before installing on the real system
- Check out new controls and operating strategies
- Verify process design and study effects of modifications to the process
by altering the model
- Optimise the control system and process to maximise economic performance
- Train the control operators and instrumental engineers prior to process
start-up
- Familiarise and train new plant personnel before they are assigned to the
plant
- Re-train experienced process operators to identify abnormal process conditions
and methods of dealing with them
- Re-train experienced operators to optimise the process for maximum economic
performance
Ready made exercises

We acknowledge that installing a simulator to train personnel is only one part
of the equation. The training that is carried out must be structured and consistent.
To assist our customers and increase training efficiency from simulation we have,
together with our customers, developed a set of “ready to go” exercises as listed
below:
- Exercise one: Test of combustion air fan at various load conditions
- Exercise two: The effect of shut off of high pressure feed water pre-heaters
- Exercise three: The use of one or three feed water pumps in operation
- Exercise four: The relationship between electric and heat production
- Exercise five: Heat balance in steam generator and fuel oil pre-heater
- Exercise six: The effect of decreasing the super-heater temperature
- Exercise seven: Power factors and Sankey-diagram
- Exercise eight: The effect of changing cooling water temperature
- Exercise nine: Change of the combustion air relative humidity
- Exercise ten: Heat effect and temperature distribution in boiler
- Exercise eleven: High pressure turbine in hs-diagram
- Exercise twelve: Intermediate turbine in hs-diagram
- Exercise thirteen: Combustion and boiler power factor
The simulator software is designed to enable a plug in CO2 trap system (option)
when commercially available.
With our thermal power plant simulator and exercises you can perform and deliver
structured, consistent training to your thermal power plant personnel and benefit
from the improved efficiency and safety of their thermal power plant operations.
