DESIGNING ELECTROMAGNETIC COMPATIBILITY
AT 110-500 kV SUBSTATIONS
The article is devoted to the methodology of designing electromagnetic compatibility at 110-500 kV substations, which was developed for the “Energosetproject” directorate of the “Ural Energy Engineering Center” JSC. The article describes the main results of 4 years of electromagnetic compatibility design, including soil testing methodology and the performance of special engineering calculations.
1. INTRODUCTION
Nowadays, at modern 110-500 kV substations, a large amount of microprocessor devices is used in substation automation, relay protection, telemechanics, and communications.
All these devices have low levels of normal operating stability in the harsh electromagnetic environment that exists at high-voltage substations. That is why, since 2006, all 110-500 kV substation projects at the “Energosetproject” directorate of the Urals Power Engineering Company have included a special section devoted to the design of electromagnetic compatibility. From that time until April 2010, we completed more than 20 EMC projects. This article depicts our main results from 4 years of EMC design experience. (…)
