Wireless sensor networks (WSN), as a cutting-edge techniques in information acquisition and processing, can be widely used in many areas. WSN used in fault localization system on power grid cables is the research focus of intelligent power grid. We improve the traditional DV_Hop algorithm and propose a feasible method of failure localization which can be applied on power grid cables.
This paper briefly describes the characteristics of wireless sensor networks (WSN) and introduces it into the power grid. WSN can dynamically monitor malfunctions on power grid cables. This is the significance of the article. We make some improvements on the DV_Hop algorithm in WSN and propose a feasible method of failure localization which can be applied on power grid cables.
To study the on grid wind turbine generator made in china, three types of horizontal axis three-blade wind turbine generator were researched. The design of wind turbine and the factors which influence the property of the wind wheel were studied. The mathematical model and operation principle of wind turbine with squirrel cage induction generator, doubly-fed induction generator and permanent magnet...
Pitch control by controlling the pitch angle of the wind wheel blade of the wind turbine generator can control the rotation speed when the wind turbine generator is starting and the output power when the wind turbine generator is on grid. The wind wheel can get maximum wind energy when its blade tip speed ratio is an optimum value. When wind speed is less than the rated speed, the rotation speed of...
