Abstract
Current situation of world energy is ing increasingly grim. Domestic coal
price is rising rapidly, which significantly reduce the panies’ profits.
Coupled with increasing energy conservation and emission reduction efforts, the
survival and development of thermal power plants are facing a huge challenge. The
study operation evaluation system of power plants based on energy saving is to
reduce coal-powered thermal power. According to the unit operation conditions
change the optimal value of baseline indicators, the use of scientific methods of
performance management to effectively motivate and guide timely adjustment of
operating personnel unit operation mode, to ensure the safe operation of generating
units on the basis of the optimal operating state, in order to achieve energy saving
unit, and effectively improve the power of economic and social benefits.
In this paper, based on ideas of operation performance evaluation of energy
saving thermal power units and based on the study of unit energy consumption
analysis and loss analysis theory, it is proved by case analysis that the energy loss
model and loss analysis model of the thermal power units turn to be scientific and
accurate. It has built the perfect running performance assessment model, which can
be applied to all types of domestic thermal power
