| Abstract: | Based on the heating exchange character analysis of heating system, control scheme for the heating system is designed. The regulation time is decreased through adopting temperature-pressure cascade control scheme to control average temperature of supply water and backwater in secondary pipe network. The energy consumption is reduced through using frequency conversion technology to control the supplement water＇s pressure. The monitoring picture is compiled based on the configuration software. This system can help managers of district heating systems to monitor the local operating mode and regulate operating parameters effectively. Therefore, the safety, stability and economy of a district heating system can be improved. |
