Methods and systems for balancing mass flow during production failure or insufficient in district heating networks

摘要

A method for balancing mass flow during production failure or insufficient in a district heating network comprising a plurality of substations, each substation having at least one connected to the district heating network for transferring heat between the district heating network and the substation. a secondary side connected to at least one space heating circuit for heating at least one space connected to the substation, and an adjustable valve 102 arranged between the substation and the district heating network, The valve 102 is controlled by a heating curve f defining the calculated supply temperature T supply,calc for the space heating circuit for the secondary side of the substation as a function of the measured outdoor temperature T outdoor . do. The method further includes heating curve compensation for each substation and population compensation for all substations of the population. The results are then used to control the valves 102 of the individual substations.
