Previous Research Of The Applications Of ZigBee Technology On Power Plant

To realize Electric power plant informationization, equipment monitoring and supervisory control system need to gain large amount of equipment information. Along with the development and application of modern short distance, low-power consumption wireless communication technology, especially ZigBee technology, the sensor information acquisition technology from the sole wired technology to the technology which wired and wireless unifies, from simplification to integration, miniaturization, then intellectualization, network, become the new means of access to information, thus presents the ZigBee sensor network technology and application.The thesis major task: the earlier period research of the electric power plant to apply the ZigBee sensor technology, including the research of necessity, feasibility, security reliability, cost and so on; the preliminary technological strength for the ZigBee sensor network technology next step research and application. The Main contents of the thesis as follows:â‘ Elaborated the short distance wireless communication technology. Analyzed and compared modern mainstream short distance wireless communication standards: The Bluetooth technology, the ZigBee technology and the Wi-Fi technology, respectively. Proved that based on the ZigBee technology's sensor network is one of ideal plans.â‘¡Elaborated the ZigBee technology content and technical performance. Introduced the IEEE802.15.4 technical standard and analyzed the sensor and the sensor network technology. Studied the ZigBee sensor network agreement and network topology detailedly, particularly the node constitution and network software technology with emphasis. Researched on the ZigBee sensor network middleware technology, gateway, bridge, route agreement and principle, as well as route algorithm basic process. Analyzed the factor and design principle of the ZigBee network and gave the ZigBee sensor network function valuation standard.â‘¢The priority of the thesis:First, presented the current situation and superiority of the electrical power system to apply the ZigBee technology, analyzed and proved the ZigBee sensor network technology safety and reliability. Then the power plant equipment's ZigBee technology radio-frequency signal, namely harmonic test result, is given. Results demonstrate that the radio signal does not affect primary equipment safe and stable operation.Emphatically Analysis and demonstration: ZigBee technology radio-frequency signal to power plant secondary equipment's influences and countermeasures. We developed and applied many new anti-interference (such as anti radio-frequency signal) technologies to improved secondary equipment's robustness. Practice proved that the new technical application's result is remarkable. The power plant secondary equipment anti-interference ability is stronger and stronger, and it is already prepared for researching and developing to apply the ZigBee sensor technology.The paper gave the situation, condition and transmission data type that meets the requirements of ZigBee technology apply to the power plant application. Prospect the future power plant monitor and the supervisory system hierarchical structure, as well as three kind of fundamental models of the power plant applying the ZigBee sensor network. The ZigBee sensor technology can completely meets the requirement of future power plant equipment's surveillance and supervisory. That the ZigBee technology applies to the power plant is essential, feasible and security.
