Abstract:

The online line-loss calculation platform with province and region integration uses the CIM model interface and imports grid models directly from the EMS, which does not require building the model manually and repetitively. It can track the changes of the grid model, and ensure the qualified rate of state estimation at a higher level, which can lay the foundation for the accuracy statistics and computation of the loss-loss. The power data provided in the platform can covered all grid models of 110 kV and above, which is the verification and important supplement of power data collection system. Based on this platform, it can provide a more comprehensive analysis platform of network-loss for the staff, and find an effective way to reduce network-loss through the analysis of system loss and equipment loss under various operation modes. The theoretical calculations of line-loss in Hebei South Grid under typical daily load mode have been carried out by using this platform. Through the daily line loss analysis, it can find the problems of online data in the EMS system in time, which can improve the qualified rate of system state estimation.
