The Application Of Unit System In Distribution Network Operation And Control

Distribution network because of its points, wide surface, complex structure and so on, for a long time operation and management of the distribution network has been in a relatively weak link. Jiangsu electric power company in order to improve the lean management level of distribution network, within the scope of application of jiangsuprovinceplanning method. However, in the current system of power unit management background, the existing operation control technology have been unable to meet the needs of the safe and stable operation of power distribution network, needs to carry out the system of distribution network based on unit operation control key technology research and application.To solve the problems existing in the power distribution network management, this paper introduces the concept of grid unit system, this paper introduces the steps of grid unit system planning, combining with the actual example of zhenjiang power distribution network planning, the different types of cells are classified according to the load development, then introduces the different types of cell respectively concrete way. To improve the distribution network operation management level, speed up the application of the power unit system, this paper based on the grid unit operation platform on the basis of the regulation of the distribution network, proposed grid-enabled warning analysis and recognition, grid DA, grid quasi real-time state estimation of line loss analysis function concept, and the application of these functions in zhenjiang power control operation done.Finally shows the application effect of the above techniques. It can be seen that run through the system of distribution network based on the grid unit control technology application of power distribution network management interface more clear, accident treatment more convenient, more accurate measurement data of the distribution of great convenience to regulate the application of part, and improve the level of the regulation of the distribution network operation.
