Turbine performance analysis by simulation modelling by SK Goyal, General Manager-Mechanical and CPP services at Corporate Technical and Energy Services and Monesh Sharma, Manager-Mechanical at Corporate Technical and Energy Services, Aditya Birla Group.
Thermodynamic simulation modelling is proved to be one of the best methods for the analysis of a captive power plant. The case study mentioned below gives an example of turbine performance analysis and prediction of thermal energy saving by improvement in some critical parameters like turbine inlet steam temperature and vacuum.
Simulation models can be very effective tools if we want to analyse thermal power plant systems or processes. The following picture shows the various areas where we can use the simulation method.
Simulation modelling is widely applied for analysis and forecast. Such models have always been very useful in providing solutions related to process energy efficiency and conservation.
Benefits of simulation modelling
Simulation modelling has the following benefits: 1. Individual performance of all critical components of a power plant like boiler, turbine, condenser, feed water heaters, etc. can be analysed. 2. Performance analysis of integrated power plants having multiple units of boilers and turbines can be carried out in minimum possible time. 3. Simulation modelling is very helpful in power plants designing and optimisation projects. 4. What-if analysis can be done in a very accurate and convenient way by simulation modelling. 5. Simulation modelling helps in understanding the effect of process variation on power plant in cogeneration system.
6. Performance can be predicted if a new component (for example HP heater) is added in power plant cycle.
7. Operation and maintenance planning can be done effectively and unwanted forced outages can be avoided.
So simulation models can be very effective tools to analyse thermal power plant performance and identify improvement areas.
