Power unit’s efficiency and indicators

 

Thermal power plant Production Planning and Statistics Department uses several indices that describe plant's operation .

 

Generator Circle Chart

Normative service supplies', electric power and in-plant thermal power consumption indices and many others are determined in real-time for ongoing operation purposes.

Basing on performed calculations, generated thermal and electric power distribution graphs are displayed for billing periods as well as time graphs describing power generation during a selected period. The type of indices and graphs is determined individually, according to each power plant specifics.

 
 

Inlet steam pressure and temperature permissible variation range

 

Sample figures describing the turbine set may have the following values:

  • internal efficiency of individual turbine stages
  • power transmitted to turbine shaft in its individual stages
  • power generated by steam directed to condenser and steam used for heating purposes
  • electric and thermal power cogeneration coefficient
  • electric power generation efficiency in cogeneration with heat production
  • heat rate consumption for electric power production
