For two 330 MW units made by Romania and installed in Huadian Pucheng Power Generating Co Ltd, unusual temperature variation concerning medium-pressure cylinder has occurred in start-up process of said units.

A safety and economic analysis of 2×300 MW units and 2×330 MW units participating in peak-regulating operation for a load of 100 MW has been carried out,and the corresponding operation measure being proposed.

Research on economic efficiency of low load operation in large thermal power units;

Energy-loss analyzing model based on asset/architecture reuse technology for thermal power unit;

Research of compound fuzzy control and its application to thermal power units

Based on the existing information source in the power plant, the Energy loss Analysis System for power unit in Client/Server is developed, in which three new math models is used and so this system has the charteristics of high accuracy, convenient maintaining and saving the computer source of the power plant.

This article discusses the significance and the method to attain some operation index when diagnosing the energy\|loss and analyzing energy\|saving for power unit under different loads.

With the implementation of saving energy and declining energy loss in power plant and the increasing request of the units’operational level,it is very important to research thermal power unit optimization operational guidance.
