A Calculation Method of the Optimal Initial Steam Pressure of the Power Plant Based on Model Analysis

The shortage of control system for the air-cooling unit is the lack of theoretical guidance and relative operating experience in the selection of operating mode. The mathematical model is built to optimize the initial steam pressure of the air-cooling unit with the method of systemic analysis. Through calculation of air-cooling unit NZK600-16.7/537/537-Ⅰ, the optimal initial steam pressure curves in different work conditions are obtained. The analysis will improve the optimal system-wide control theory of air-cooling power plant. Limitation of the initial steam pressure curve provided by manufactory is also analyzed in this paper.
