In recent years, power management and power economic management is one of hot topics, the studies of wireless network are more and more popular such as ZigBee wireless sensing network, radio frequency identification (RFID) and other technologies. A great amount of wireless applications are applied to family, industry, medical and relevant environmental. Zigbee wireless sensing network and monitoring...
In this paper, we focus on studying the efficiency promoting of power generation in the application of a domestic large-scale Photovoltaic System. We suggest three cases to improve the efficiency of power generation from the photovoltaic system. Especially, the third case is the computer supported cooperative work between the Photovoltaic system and the cooling system. This article not only describes...
Saving power is the major goal in every area either in industry or in campus. However, there are more uncertainties in campus. For instances, the usages of air conditioners in the classroom are irregular events. In the other hand, the lighting in the parking area is the regular event. For the regular event, we use the unstable green energy like wind or solar to save the electric cost. For the irregular...
This paper presents a new field-weakening control scheme for surface-mounted permanent-magnet synchronous motor (SMPMSM) drives. The proposed method can determine either the constant torque limit control mode or the field-weakening control mode which should be applied to the drive under different operation conditions and variations of system parameters. In addition, the minimum copper loss operation...
