Design Of Safety Risk Identification System For Power Transmission Network Construction

In the modern society, the power grid has played a vital role in serving people's life,perfecting urban functions and promoting social and economic development. The construction and perfection of power grids have become the key way to optimize the allocation of power resources after several years of development. At this stage, the theme of grid construction is "large-capacity long-distance transmission, new energy technologies emerging, the regional interconnection of large power grids." However,natural disasters, external damage, human liability, system failure, equipment failure and other reasons often cause large-scale power outages, which has a serious threat to the safe and stable operation of the power grid. Therefore, in order to prevent the power loss caused by the huge loss, the most critical is to ensure the safe operation of the power grid,it should be timely to establish and improve the accident early warning and risk management mechanism.This paper develops a set of system software based on the "State Grid Corporation of power transmission project construction safety risk identification, assessment and pre-control measures management approach", the mobile Internet, GPS positioning technology and computer information technology effectively applied to the power transmission project Construction work safety risk control early warning and control. The second, third and fourth chapters of this paper focus on the introduction of security risk identification system software, network transmission function, data calculation and other content, using Android APP and WEB technology combined development. The fifth chapter shows the application of the system function in the form of system effectiveness,and finally realizes the working position of the supervising party and the construction side in the form of GPS positioning and electronic map alarm. And by uploading the construction process photo, Owners to master the construction process in real time,on-site security risk assessment, and develop appropriate solutions to grid engineering safety risks remain in control, in control and control of the state.Through the research and development of the system, in the specific power gridconstruction work can not only clearly identify the owners, supervisors and construction side of the transmission and distribution engineering work risk control responsibilities,and through information technology on three and above construction risks to the owners Warning, in the construction process through the GPS technology, electronic map technology and electronic photo technology to locate the supervisor and the construction side of the working position of the three and above risk processes in the construction process of real-time supervision and guidance, and greatly Reducing the risk of three and above the accident rate.
