Development And Application Of County Power Grid Dispatching Operator Error Prevention Management System

With the great leap forward development scale of Lianjiang distribution network, changing the power network structure and operation mode, more and more network scheduling tasks, requirements for the operation personnel’s service quality is more and more high, due to the lack of consideration of the "wrong judgment, operation error, error scheduling" is a major cause of the accident of power network. The dispatcher on brain memory and judgment to avoid false dispatching accidents, how to improve the work efficiency and safety scheduling has become an important issue facing the current distribution scheduling.Firstly, according to the current situation of county power grid dispatching work, carries on the demand analysis to the problem, proposed the establishment of distribution network dispatching operation management system for error prevention ideas, absorb the shortcomings of previous research results, the functions and requirements of the system, design of software and hardware structure and the system function module, realize the sharing of real time data and SCADA system, integrated with the distribution production management information system, can realize the network normal operation mode, the expert, the simulation of anti-misoperation, simulation training, operation process audit and management and other utility functions, the design and implementation of user dispatching operation maintenance management system for error prevention, automation and intelligent network scheduling production process management, improve the intelligence and security of distribution network operation.System using network topology, operation simulation, network model of practical power system; the figure ticket integration technology, implementation of operation instruction ticket intelligence generation, automatic simulation, automatic topology coloring, automatic safety checking utility function. The system is based on a real distribution network graph model of dispatching command to write intelligent software system and an error check. The system can be in a wiring diagram of direct intelligence generation scheduling of operation instruction ticket, forming operation step by clicking on the operation of equipment, the tickets at the same time, the scheduling rules and anti misoperation rules into Anti error checking basis, according to the real-time operation of power network operation refers to judge the rationality of the step, the misoperation warning or tips, improves the scheduling of operation instruction ticket generation efficiency and accuracy, make up for the current distribution network dispatching technical support system of.The system achieved the function specification intelligent operation ticket system scheduling China State Grid Corp standards, research achievements as the technology project of Lianjiang’s investment in the development of application, in the process of implementing the scene, modify and perfect the function of the system, in order to meet the needs of distribution network dispatching work. Practice has proved, system is one of the auxiliary tool for dispatcher routine work effectively, in order to effectively prevent false dispatching accidents, reduce dispatcher working strength, plays an important role to improve the management level of power grid security.
