Abstract:
Wireless communication networks are crucial for the construction and development of modern power systems. Channel measurement and modeling serve as the foundation for building wireless communication systems. In this article, the focus is on channel measurements conducted in differentiated power transformation application scenarios at frequencies of 470 MHz and 2.4 GHz. Furthermore, based on the measured channel data, the article investigates modeling methods for path loss, shadow fading, and delay spread in power transformation scenarios. A comparative analysis is conducted to compare the channel modeling results in different frequency bands and indoor/outdoor scenarios. Additionally, the modeling results are compared with the 3GPP standardized channel parameters. The results indicate significant differences between the channel parameters in power transformation scenarios and the standardized parameters set by 3GPP. The obtained channel parameters in this article fill the gap in existing standards for power scenarios and provide a fundamental channel model for the deployment and optimization of wireless communication networks in new power systems.
