In this paper, microprocessor in association with GPRS, ZigBee, PLC (Power Line Carrier) and voltage current acquisition circuit were adopted to prepare wireless cable theft detection module with detection capability of conductive cable theft for distributed low voltage circuit including overhead line and underground cable. The greatest feature of this module was its capability to monitor simultaneously...
In mining areas, wastes are usually piled-up in the dump, making a man-made hill with height of more than tens of meters. Because of the loose structure of dump sites, landslides or debris flow may occur after heavy rainfall, threatening local people's lives and properties. Therefore, dump stability monitoring and early warning for possible hazards is crucial for ensuring local safety. In this paper,...
For wind farms, the relationship between wind speed and output can be described by power curve of wind turbines, and it is an important embodiment of power performance of wind turbines. Based on the mathematical model of the power curve of wind turbine, monitoring performance of the wind turbine can be designed. Power curve model of wind turbines can be established by using Gaussian process. Within...
