Research Of Supervised System Of Grounding Wire For Transformer Substation Based On WLAN

With the improvement of the automated level of transformer station, supervising online of grounding wire embodies an important role in the safely running of grid. The purpose of the paper is to study and develop a supervising system of grounding wire based on WLAN, using technology of WLAN and embedded. This system will realize online supervising of grounding wire, which will ensure the safety of worker and equipment. This system adopted not only advanced IEEE 802.11b standard, also technology of embedded, which makes miniaturization of equipment and lower cost, and raises economic efficiency. First, the paper introduced simply importance of the online supervising of grounding wire, condition of management of grounding wire, meaning of the system. Chapter 2 introduced briefly WLAN, and focused on IEEE 802.11b standard. It introduced the hardware and software realization of the supervising of grounding wire in chapter 3. Chapter 4 analyzed the electromagnetic environment in transformer substation and designed the system anti-jamming It gave the debugging and simple trial result of supervising system in chapter 5.
