【Abstract】 Social development led to a rapid increase in demand for electricity, many fields of advanced technology is widely used in the grid makes the grid with the development trend of intelligent. With a wide range of power transmission systems, high pressure and high-capacity, the research and application of digital network technology, communication technology and real-time monitoring technology become the development direction of the electricity, it is an important part of smart grid.Based on the full investigation of the optical sensing and optical communication technology in the smart grid, an optical sensing monitoring scheme for power transmission lines is proposed and experimentally demonstrated. The Fiber Bragg Grating sensors are used to sensing the information of temperature, strain and icing thickness in the power transmission lines system, the sensing signal is transmitted to monitoring center through the optical fiber. The software based on client-server model is established to process and display the sensing information. The monitoring scheme is experimentally installed. The result shows that the monitoring scheme is a useful tool for manager to monitor power transmission lines system.In summary, the specific works of this paper are as follows:1. Introduces the concept, characteristics and features by analyses the main factors of developing intelligent power grids.2. Proposed the monitoring scheme for power transmission lines based on Fiber Bragg Grating sensors, explain in detail the calculation of various parameters and experimentally demonstrated.3. According to the demand of the monitoring scheme, the client/ server architecture real-time monitoring software was developed and tested, the result shows that the software words stably and effective.4. According to the installation and protection program, the monitoring scheme is actually set up, and some monitoring data were analyzed, the result shows that the monitoring scheme is useful.更多还原
