The present situation of rural distribution network fault location is analyzed. The characteristics of fault calling information of distribution network were discussed. On this basis the rural distribution network fault location algorithms theory based on rough set was proposed. The decision table in accordance with distribution network topology was the main tool of the algorithm, using the ability...
A tester of environmental parameters of solar energy based on ARM microprocessor of S3C2440A was introduced in this paper, the design of software and hardware and implementation methods were detailed expatiated. The environmental parameters which included temperature, humidity and illumination could be measured and displayed real-timely and adjusted the azimuth of cell panel. The data collected by...
