Development And Application Of Power Dispatching Technology Support System

As the grid system is more and more complex, the grid system is influenced by external factors increasing, adding to uncertainty of power grid operation. Power grid deployment of AMI system, EMS system, such as the PMS system, DMIS system for us to understand the grid characteristics, predict the risk of power grid operation may be provided a reference basis. Based on the theory of big data and application technology, mining analysis of power grid operation real-time data and historical data. Using big data technology, through to the power grid operation of the real-time data and historical data mining analysis, grasp the power grid operation rule, optimize the structure of power grid, control of power grid operation state, the optimization of power system resources, improve the power grid security and reliability. By analyzing the weather data, the monitoring data of electric power, the capacity, reduce the dynamic line suggestions. Through the analysis of WAMS data, power dispatching management system and the simulation calculation data, stability analysis of power grid security, establish network knowledge base, a grid disturbance, take timely measures to stabilize the power grid operation, improve the running safety of power grid.Based on the analysis of the large data with electric dispatching technology support system has become a production scheduling management of electric power dispatching integrated support platform, the construction and application helps to realize production scheduling management specialization, standardization and routing, scheduling management level and work efficiency, institution is to realize the integration of power grid dispatching management of technical support. Based on analysis of large data with electric dispatching technology support system will be all kinds of power grid operation and management of data model based on unified comprehensive processing, to replace artificial to complete data validation, storage, display, and comprehensive analysis and evaluation.Based on the analysis of the large data scheduling technology support system combining with the electric power grid running the actual demand, with the main existing dispatching automation system, distribution network automation system as the foundation, by constructing a panoramic model center, graphics, data center and unified function display platform, realize the main dispatching automation system, distribution network automation system and distribution network geographic information system, production management system, marketing, customer service system, measurement automation system, electricity information collection system across the safety information on Internet, for graphics, models, "the source side maintenance, global sharing", for business across systems global collaboration to provide strong technical support, build the production methods, operations, planning, departments and electricity users mutual perception of platform.Based on the analysis of the large data with electric dispatching technical support system based on multidimensional model of depth excavation, found that the intrinsic connection between information, surrounded with electrical failures of key concern in daily work related personnel, load, users, and many other aspects, deepen system advanced application in flexible statistics and intelligent analysis, offer is based on the analysis of the large data with perception, intelligent alarm, intelligent power electric load analysis, intelligent peak electricity management and equipment risk assessment, and other functions, real-time monitoring master, for with the electrical personnel distribution network operation, master the control center and power substation power supply load, power failure risk analysis plan, failure analysis and power cut, to do a good job of important user of electric power supply and so on all levels to provide accurate, efficient, practical and technical support.The system based on EXTJS+DWR+SPRING+IBATIS framework development running, through the JavaEE platform provides a variety of data exchange technology, adopts the distributed transaction system ensure the data security of the runtime system and accuracy.
