Dan Wang · Chinese Journal of Power Sources · 2015
The distribution network is an important part of modern power system. The working principle of data acquisition system for power distribution network was introduced, based on the technology of WSN(wireless sensor network) and Zig Bee, and the design scheme, hardware design and software implementation of the system were described. In order to improve the timeliness and accuracy of the data collection, the median average filtering method was used to filter the random disturbance, which mixed in the measure channel. The experiment proves that the method has good filtering effect not only in slow changing signal, but also in rapidly changing signal.
