The way of district heating output control by means of hydrothermal power systems

The paper deals with brief description of three modifications of the way of control of hot-water piping heat output at simultaneous operation of qualitative and also quantitative parts of control. The separate modifications are as follows: 1. Qualitative - quantitative way of control of hot-water piping heat output using prediction of the course of daily heat supply diagram in district heating systems. 2. Adaptation of qualitative - quantitative way of heat supply control for the case of using part of the piping for heat accumulation. 3. Algorithm of qualitative - quantitative way of control of hot-water piping output with using hot-water boilers as heat sources. Modifications of the way of control are different due to possibility of implementation into specific conditions in separate localities of district heating systems. Copyright © 2005 IFAC
