Description

technical field [0001] The invention relates to an information processing method, in particular to a method for processing line loss information in a low-voltage station area of ​​a power grid based on an improved forward push-back algorithm. Background technique [0002] Line loss is the abbreviation of grid power loss, which is the loss and loss of power generated in various links of power transmission, power transformation, power distribution and marketing during the process of power transmission from power plants to power users. According to the structure of line loss, line loss power can be divided into statistical line loss power, theoretical line loss power, management line loss power, etc. [0003] In a given period of time (day, month, season, year) in a power supply area or power network, all the power lost in transmission, transformation, and distribution is called line loss power, referred to as line loss power or line loss. Although a part of the line loss powe...

Problems solved by technology

Due to the large amount of data collected by this method, the accuracy of the data has a great relationship with the accuracy of the mathematical model, and the versatility is not good.

For different low-voltage distribution networks, due to the difference in line structure and operating conditions, the mathematical model will always change, the cumbersomeness of calculation and programming will continue to increase, and the accuracy of calculation will decrease. From the current situation, it has little room for development in low-voltage station areas. Big
