Energy saving analysis of supervisory control and data acquisition system applied in district heating

Supervisory control and data acquisition (SCADA) system was employed in a thermal power corporation. The system aimed to improve management in district heating system of the corporation. The heating area that the SCADA system serves was 8.48 million square meters. It was, up to now, the largest district heating systems that had installed a SCADA system in China. This paper introduced the basic configuration of the SCADA system and analyzed its energy saving effect in heating system operation. The using of SCADA system had led to notable energy saving in heating and reduced running costs. The control strategies in the SCADA system were also introduced.
