Abstract

The invention discloses a queuing theory-based data transmission bandwidth prediction method in the intelligent power distribution and consumption business, aiming at the problem that a great deviation exists between a predicted value of a bandwidth and an actual demand value easily caused by the traditional bandwidth prediction method. The method comprises the following steps of firstly acquiring intelligent power distribution and consumption business QoS (quality of service) requirement parameters from an application layer as basic data for bandwidth prediction, and converting the QoS parameters of an upper layer into queuing theory model parameters through the queuing theory; secondly determining a queuing theory-based transmission bandwidth prediction model according to the QoS constraint condition of the electric power telecommunication business, and meanwhile converting the prediction model into a linear constraint nonlinear programming solving model to obtain the optimal solution; finally obtaining a smallest predicted transmission bandwidth capable of ensuring the QoS requirement of the system business. According to the method, the predicted band width is obtained by modeling and solving through intelligent power distribution and consumption business QoS parameter mapping and the queuing theory, so that the bandwidth prediction deviation is reduced, and the system bandwidth utilization rate is optimized.

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...
