STUDY OF THE EFFECT OF AC DRIVE SYSTEM ON THE ENERGY-SAVING OF AUTOMATIC CONTROL SYSTEM FOR GREEN INTELLIGENT BUILDINGS

The air-conditioner monitor system is a subsystem in the green intelligent buildings automation system, and the AC drive system directly affects the energy-saving of central air-conditioner and automation system of the whole building. According to the structure and operating principle of the monitoring system for central air-conditioning, widening dead-time in the voltage PWM (Pulse width modulation) inverter to realise improving the dead-time influence is produced in this paper and its feasibility is proved by the simulation and analysis. This will help to improve the energy-efficiency of the central air-conditioning and the whole building automation system and will provide reference for the development of frequency control theory research and the building automation industry.
