Improvement of management of steam generators in nuclear and thermal power plants

Abstract

The paper formulated optimization problem formulation production of carbon products. The analysis of technical and economic parameters that can be used to optimize the production of carbonaceous products had been done by the author. To evaluate the efficiency of the energy-intensive production uses several technical and economic indicators. In particular, the specific cost, productivity, income and profitability of production. Based on a detailed analysis had been formulated optimality criterion that takes into account the technological components of profitability. The components in detail the criteria and the proposed method of calculating non-trivial, one of them - the production cost of each product. When solving the optimization problem of technological modes of production into account constraints on the variables are optimized. Thus, restrictions may be expressed on the number of each product produced. Have been formulated the method of calculating the cost per unit of product. Attention is paid to the quality indices of finished products as an additional constraint in the optimization problem. As a result have been formulated the general problem of optimizing the production of carbon products, which includes the optimality criterion and restrictions.

В статті запропонована альтернатива класичній трьохімпульсній системі автоматичного керування рівнем води в барабані парогенераторів. Розроблена система забезпечує інваріантність до збурення зміною витрати живильної води та виробленої пари, а також дозволяє суттєво зменшити час керування. Впровадження системи дозволить підвищити надійність та тривалість неперервної роботи парогенераторів і турбін ТЕС та АЕС.
