The Computational Model of the Peak Regulation Capacity of Cogeneration Units and Its Application

Studying the peak regulation capacity of cogeneration units is of positive significance to improve the power grid dispatching capacity and promote the new energy source. In order to scientifically calculate the peak shaving capacity of a cogeneration unit, the variable condition calculation model is built up based on the theory of equivalent heat drop, and the load constraint model is also established according to the actual situation, on this basis the complete computational model of the peak regulation capacity of cogeneration units is obtained. Based on a 350MW cogeneration unit in Shandong province, the peak regulation capacity calculation is carried out, and the factors affecting the peak regulation capacity of the unit are analyzed. Compared with the experimental results, the calculation model of the peak regulation capacity in this paper shows a high precision, and can be used to predict the peak regulation capacity of the cogeneration units in different working conditions.
