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
