The Research Of Early Warning Information Entry Equipments On DC Transmission Project

Routing inspection and maintenance of transmission line and equipments is becoming more and more important after a number of DC projects put into operation。At present,some transmission line are still needed to be examined by people.Workers are unable to find problems if there is any displacement of transmission line or equipments because of the running characteristics. The research of early warning information entry equipments on DC transmission project judges the destructiveness of transmission equipment by comparing the standard information and information of site testing,and then informs routing inspectors.In this way, the efficiency of inspection is improved.The equipments provides ground surveillance, which make it safer and easier to use. The Research relates to many important theories, has a hot perspective in the operation of keeping the power systems more secure,more reliable and cheaper.In this passage,firstly,we simulate and analyze electric field distributing of transmission line with invariable parameters,which tells the differences of height and horizontal displacement of transmission line in electric field distribution.secondly,according to the test results of ion flow,wind speed,air humidity and testing position, we design the structure of equipment.。Lastly,we study each module of equipment, complete the software and hardware design of information collecting,information processing and controling modules.Finally,through analysis of site measurement data,this passage verify the correctness of the theory. If further research and utility improvement are realized,this device can help to improve the efficiency of the service network and guarantee normal operation of power grid.
