As the wireless receiver sensitivity levels surpass thermal noise levels, reliable operation of smart grid Distributed Generating System (DGS) wireless communication and control devices demands consideration of the power line produced noise spectrum. The power line noise spectrum varies based on voltage and current of transmission lines and load characteristics. The electrical-noise environment is anticipated to be more severe in a DGS than in a Conventional Electrical Power System (CEPS) due to the frequent changes in power distribution routing. While most measurable noise occurs at frequencies less than 200 MHz, the corona noise spectrum extends up to 2000 MHz. The corona noise spectrum measured near a 26 kV substation was compared with corona generated in the laboratory. Using this data, in-band wireless receiver susceptibility levels for GSM, CDMA and LTE modulation techniques were experimentally evaluated and presented.
