ALANT CPPLICATION RESEARCH OF FIELDBUS IN HEATING AND POWER PONTROL SYSTEMS

摘要

In the heating and power plant, one of most important measures used to save energy and reduce consumption is the utilization of advanced automation technology. Fieldbus is the hot point of research in automation today. The paper discusses communication features of interconnected devices and the requirements that fieldbus in heating and power plant must fulfill. According these features, through analyzing 8 fieldbus standards in IEC61158, we consider that FF is most suitable for power plant control system. Based on FF H1 and H2, hierarchy model of the heating and power plant comprehensive automation system is presented. Some problems with this model are also discussed.
