Optimizing the operation of an urban district heating system by means of variable speed drives

In this work is presenting an urban district heating system which is subjected to a modernization process. The urban district heating system is composed by the pumping station of the primary heat carrier and the district heating stations. The modernization is based on using variable speed, that allows the complete automation of the operation and obtaining of a high energetic efficiency during exploitation. The experimental results from the first operational year are used to optimize the system.
