Abstract

The invention discloses a method for predicting the bandwidth of intelligent power distribution business data transmission based on queuing theory. Aiming at the problem that the existing bandwidth prediction method is likely to cause a large deviation between the predicted value of the bandwidth and the actual demand value, the method first obtains the bandwidth from The QoS requirement parameters of the intelligent power distribution service at the application layer are used as the basic data for bandwidth prediction, and the high-level QoS parameter indicators are converted into queuing theory model parameters through queuing theory; secondly, the transmission bandwidth prediction based on queuing theory is determined according to the QoS constraints of power communication services At the same time, the prediction model is converted into a linear constraint nonlinear programming solution model to obtain the optimal solution; finally, the minimum prediction transmission bandwidth that can guarantee the system service QoS requirements is obtained. The method obtains the predicted bandwidth through intelligent power distribution service QoS parameter mapping and queuing theory modeling, which can reduce bandwidth prediction deviation and optimize system bandwidth utilization.

Description

technical field [0001] The invention belongs to the technical field of intelligent power distribution and utilization communication, and in particular relates to a method for predicting the data transmission bandwidth of intelligent power distribution and utilization business based on queuing theory. Background technique [0002] With the rapid development of smart grid and the continuous emergence of new communication services, computer networks have been widely used in power systems, and the fast, efficient and reliable information transmission methods of power communication have become the basis of power system production and management. When the power system designs its communication network, it must first determine the various application services it needs and its quality of service (QoS: Quality of Service) requirements, and then predict the necessary transmission bandwidth of the communication system. Therefore, the prediction of power communication service transmissi...
