Although researchers have put much effort to identify power disturbances and reduce their influences, many of the identification methods were not utilized by power companies due to technical restrictions. In this proposal, we intent to integrate wireless sensor networks, cloud computing, Internet, LabVIEW, and web-services to provide several useful functions, e.g. power quality assessment, power energy accumulation, power distortion warning, power restoration alerting, and power stealing alerting. During the development of this project, all systems will be built based on widely utilized wireless communication protocols (i.e., the Internet) and hardware development kits (i.e., FPGA or MSP development boards). We will also try to modularize the sensor node and the internal private cloud server to ease the installation of the entire monitoring system. To boost the applicability of the proposed system, utilizations of specialized protocols or hardware that are hard to obtain and dedicated only for power companies will be reduced, and thus any possible incompatibility problem will be minimized. Finally, this project will implement two sensor networks (that contain 2 internal private cloud servers and 10 sensor nodes) and a monitoring system. The power quality assessment network will be comprehensively tested, and we will continuously adjust the design of MAC to maintain the stability of system operations嵌入式系統電力品質監測竊電偵測自動計量讀表警報系統無線通信協定無線感測網路Embedded systemspower quality analysispower stealing detectionsmart energy meterwarning systemswireless communication protocolwireless sensor networks.
