Embodiment Construction
[0037] The technology of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] Such as figure 1 Shown is a schematic diagram of the communication node of the power distribution service convergence substation of the present invention; the power distribution service received by the substation communication node includes power distribution equipment status monitoring service, distributed power supply monitoring service, power collection service and power quality management service , the four types of services are all single-service data packet streams. After the substation communication node receives the four types of single-services, it aggregates into multi-service aggregated data packet streams and sends them to the power three-level communication backbone network.

The invention discloses a method for predicting a power distribution / utilization self-similar aggregated service communication bandwidth of a transformer substation. The method comprises the steps of collecting a time sequence composed of data rates at which distribution and utilization services arrive in a communication node of the transformer substation to form aggregated flows as basic data for bandwidth prediction, performing data cleaning processing on the basic data for bandwidth prediction by use of a weighting smoothing method, training an FBM self-similar traffic model for the bandwidth prediction of the communication node of the transformer substation by taking a plurality of pieces of service rate data obtained after the data cleaning processing as training samples, and predicting and distributing the distribution and utilization services of the communication node of the transformer substation by use of the trained FBM self-similar aggregated traffic model. The method has the advantages of overcoming that a traditional method is incapable of describing the influence of the self-similar aggregated dynamic characteristics of the distribution and utilization services on bandwidth prediction, reducing a deviation between the prediction result and the actual needed bandwidth and increasing the utilization rate of system bandwidth; as a result, the communication cost can be reduced, and the economic benefit and the social benefit of power system communication can be increased.
Description
technical field [0001] The invention belongs to the technical field of intelligent power distribution and utilization communication, and in particular relates to a communication bandwidth prediction method for substation power distribution and utilization business. Background technique [0002] Distribution communication services are mainly divided into two categories: one is various information around distribution network equipment, that is, distribution automation; the other is various services around users, which are mainly used in the collection of user power information. The service of obtaining power distribution and consumption includes: power distribution equipment status monitoring service, distributed power supply monitoring service, power collection service, and power quality management service. With the rapid development of smart grid and the continuous emergence of new business of power distribution and consumption, the fast, efficient and reliable information t...
