Embodiment Construction

[0047] The path loss modeling method provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] Such as figure 1 The overall scheme implementation flowchart of the present invention shown, in the modeling method of the path loss model provided by the present invention, comprise the following steps:

[0049] (1) Establish the original measurement data measurement scheme of the path loss model;

[0050] Such as figure 2 and image 3 As shown, they are the distribution diagrams of actually measuring the received power of wireless signals in 110kV and 220kV substations respectively. During the measurement process, the wireless signal source to be tested is placed in the communication room of the substation, and the position is fixed. The transmitting equipment consists of a signal source and a transmitting antenna. Composition, the signal source adopts AV1441A radio frequency signal generator, and the tra...

Abstract

The invention provides a path loss modeling method for a transformer substation environment. The method comprises the following steps of establishing a data measurement scheme, collecting data, establishing a path loss model and determining parameters of the path loss model. In the technical scheme provided by the invention, a large amount of sample data is not needed, the path loss property of a wireless signal in a transformer substation can be determined precisely and effectively, and the parameters obtained through computation can be better coincident to the measured data of a wireless channel.

Description

technical field [0001] The invention relates to the technical field of electric power wireless communication, in particular to a path loss modeling method for a substation environment. Background technique [0002] The smart grid, which uses power grids at all levels as the foundation of the grid, utilizes information and communication platforms established by various new technologies to realize comprehensive management of power transmission, power grid operation, and power business. As an important means of power information transmission, wireless communication has achieved fast and convenient communication, but it also faces many challenges. [0003] Taking the application environment of high-voltage substations as an example, since the electrical equipment of high-voltage substations will generate electromagnetic interference during operation, wireless communication equipment placed in substations with very harsh electromagnetic environments will be subject to different d...
