Research On Online Security Early Warning System For Lianyungang Power Grid

In recent years, along with China’s economy continued to improve, power system security level has undergone tremendous changes. Grid growing scale, the safe and stable operation of the local economic development has an important influence, to ensure security and stability operation should begin defense of risk, the ability to detect weak points in the grid system that may occur and will likely affect the security and stability of the system event occurs, and to take appropriate measures. Lianyungang supply companies in the region belong to the Jiangsu Provincial Power Company, due to the rapid development of the local economy, to ensure grid security and stability is the primary task of sustained local economic development, which urgently needs to be building supply companies Lianyungang grid security warning system, this paper is built on the theoretical basis of this system has made on the analysis and research.First, we propose to define the status quo power line safety warning systems and the development of domestic and foreign, and gives the main function of power line safety warning systems, characteristics and advantages. This system without human intervention, automatically and continuously track the status of the power grid to determine grid security level grid emergency alarm, warning grid potential security threat, able to give a visual control of the decision-making preventive safety report for fast processing power dispatcher emergency provide important reference. And details of the grid accident case online security warning system to carry out the work processes and decision-making systems work.Secondly, Lianyungang regional grid Online Safety Warning System management provides an overview of the status quo, and the current grid security Lianyungang regional early warning system has been introduced, are described in its application, pointed out the inadequacies, and analyzes the regional power grid Lianyungang major crisis and response measures and the next building new online safety warning system and the need for early warning direction.Thirdly, the paper analyzes the overall framework of the grid structure Online Safety Warning System Network model reconstruction, and then combined with the characteristics of the external network within the framework of equivalence, boundary matching and network consolidation and other specific key technical issues are described and theoretical analysis. Analyzes the visualization techniques and hardware framework design principles grid Online Safety Warning System and focused to achieve the functionality presented online security warning system in accordance with the power system operating state hierarchical display options.Finally, the combination of theory and the actual situation in Lianyungang area, the paper grid Online Safety warning system designed Lianyungang areas, and gives the design and realization of the four early warning function, namely static security warning, safety warning voltage transient safety warning and assessment section of the power limit, and its function introduced in recent years, combined with Lianyungang representative track and analyze primary equipment failure, effectively verify the practical value and application prospects of the system.
