System-wide Model Analysis Technology of Abnormal Line Loss Based on Dynamic Parameters and Global Variable Prediction

Nowadays line loss has become one of the most important assessment indicators for power grid enterprises and power generation enterprises. Line loss is not only an important indicator linked with economy, but also has a far-reaching impact on the economic operation status of power enterprises. At the same time, abnormal line loss is often positively correlated with the poor operation status of equipment and backward operation mode and so on. In fact, solving an abnormal line loss problem is also a solution to the hidden troubles of primary and secondary equipment and improvement of the operation mode of power grid, which has a far-reaching impact on the stable, safe and stable operation of power grid. In this investigation, the factors affecting line loss are found out through large data analysis. Based on the configuration of primary and secondary equipment, the whole system-wide model of line loss is established by using dynamic parameter method. The equipment or operation mode that causes abnormal line loss analysis is divided into two parts. The rectification scheme is evaluated, and the Lean Management Level of Line Loss is guaranteed.
