TRAINING PENGENALAN AUXILIARY POWER MEASUREMENT, OPTIMIZATION AND ANALYSIS
TRAINING POWER MEASUREMENT
OUTLINE MATERI Training Auxiliary Power Measurement, Optimization And
Analysis :
1. Power Plant–Fossil fuels
* Fossil fueled fired generating stations have very precise
definition of Thermal efficiency.
* It is the ratio of heat equivalent of Fuel fired to the heat
equivalent of electricity sent to transmission net work.
* Auxiliary power consumption has two components.
* Unit auxiliary power consumption & station auxiliary power
consumption.
2. Power plant cycle efficiency
* Role of Steam Generator is to generate steam which is used to
convert heat energy into kinetic energy.
* Conversion cost includes usage of steam produced for internal
consumption such as SCAPH ,TDBFP, Air Condtioning based on VAS
* Aux. power consumption would depend on coal quality and on type of
cycle.
* Why not use better coal, which would lower auxiliary power
consumption and an optimum performance can be sustained with less
expenditure on O&M Cost.
3. Power plant cycle efficiency
* Gross boiler efficiency at any point of operation can be improved
by consuming more electricity through Mills & fans.
* When we are using low cost–inferior coals- we consume more
auxiliary power consumption to improve operating efficiency.
* Usage of an additional pulverizer to handle poor coal results in
increased power consumption, however, corresponding improvement in
Gross boiler efficiency may not be achieved.
4. Importance of Auxiliary Power Consumption
* Degradation of equipment performance can be readily guaged from
power consumption .
* Unit or boiler power consumption is monitored as % of generation
which is just a gross index.
* Power consumption guarantee on boiler covers all major drives
* Power consumption should be measured together in a typical boiler
efficiency test.
5. Change in plant Conditions with time increases Auxiliary power
* Air in leakage to boiler gas enclosure
* Fouling of Boiler heating Surface–higher dry gas loss would
increase power consumption
* Higher draft loss due to air ingress and ash deposition.
* Air heater leakage/ Air ingress after APH’s
* Deterioration of Turbine Steam Path Condition.
* Condenser pressure/ condenser cleanliness- air ingress and extent
of tube pluggage
* Steam and water leaks from drains and vents.
6. Net Heat Rate
* Net heat rate monitoring would cover impact of aux. Power
consumption of different drive
* Net heat rate monitoring can be adopted for inernal processess.
* This would call for individual monitoring of drives using accurate
energy meters .
* Such a system is being introduced as a retrofit in all old
plants in ntpc & consumption levels are being tracked from
overhaul to overhaul.
7. Major Drives
* Drives are listed for a typical 500 mw unit.
* Auxiliary power consumption measurement can be done as per a
standard test code.
* However no test code covers correction methodology which would be
worked out based on process design.
8. Performance Analysis
* Measured total power could be different from base line values for
changes in operating regime
* It shall be higher wherever boiler performance has degraded
* Gross power could be same because some auxiliaries may be doing
better and some operating at worse point due to performance
degradation
9. Correction Methodology
* Correction methodology is jointly developed with vendor as it is
not generally covered in test codes
* Application of correction requires accurate monitoring of process
parametes using accurate off line instruments
* Coal variation would have major effect on unit performance and
thus power consumption
10. Boiler Feed Pump
* Boiler feed pump is not a boiler
* Auxiliary and its power consumption varies in response to turbine
mode of working and its degradation
11. Boiler Feed Pump
* Bfp power consumption constitute a major chunk of power consumed
by unit auxiliaries.
* Usage of steam driven feed pump results in reduction of apc %.
* Usage of turbo driven feedpump improves cycle efficiency.
* Any feedback on tdbfp performance due to condenser degradation
