Abstract

Early fault diagnosis plays a very important role in the modern energy production systems. The wind turbine machine requires a regular maintenance to guarantee an acceptable lifetime and to minimize production loss. In order to implement a fast, proactive condition monitoring, ESPRIT method seems the correct choice due to its robustness in improving the frequency and amplitude detection. Nevertheless, it has a very complex computation to implement in real time. To avoid this problem, a Fast-ESPRIT algorithm that combined the IIR band-pass filtering technique, the decimation technique and the original ESPRIT method were employed to enhance extracting accurately frequencies and their magnitudes from the wind stator current. The proposed algorithm has been evaluated by computer simulations with many fault scenarios. Study results demonstrate the performance of Fast-ESPRIT allowing fast and high resolution harmonics identification with minimum computation time and less memory cost.

Abstract

Many researchers assume that the distribution of the nodes is done in a two-dimensional environment in the reason that the height of this network is negligible compared to its width and length. However, in the reality, three-dimensional (3D) deployment of the wireless sensor networks is used. Therefore, many applications require 3D architecture such as underwater, space communications, atmospheric, forest or building. Unfortunately, the energy consumption and throughput in the 3D environment decreases considerably compared to 2D in which we can’t neglect them in some applications. In his paper we applied the 3D architecture in LEACH protocol and we prove by computer simulation how this 2D approximation is not reasonable since the lifetime of 3D WSN decrease by about 21% over than 2D WSN.
