An Electric Power Asset Localization Scheme Based on LLA and ZigBee

Since the number of electric power assets is huge and most of them are expensive, it is a great challenge for power enterprises to know each change of assets when replaced or repaired. Moreover, power asset localization is a growing practice in application, so it is important to acquire the device´s current location. Thus, this article proposed a new power asset localization scheme, employing ZigBee technology for networking and high-precision LLA algorithm for positioning. Experimental results show that the scheme achieves high accuracy flexibly and controls equipment status in real time, ensuring the assets´ security.
