PES Webinar - Electromagnetic Compatibility between AC Overhead Transmission Lines and Metallic Pipelines
IEEE Power & Energy Society Technical Webinar Series
Electromagnetic Compatibility between AC Overhead Transmission Lines and Metallic Pipelines
25 August 2016 • 1:00 pm Eastern
Presented by Jose Daconti, Senior Staff Consultant, Siemens Power Technologies International (Siemens PTI)
Difficulties in obtaining new rights-of-way for high voltage power lines and pipelines have increased the trend of locating these facilities within shared corridors. Problems that can arise from these close proximities will be addressed in this webinar.
Initially, overhead transmission line modeling under normal operating conditions and under single-line-to-ground faults will be presented. In addition, relevant overhead line and pipeline electrical parameters will be examined. Next, minimum safe distances between overhead lines and pipelines will be discussed. Then, capacitive, inductive and conductive coupling mechanisms and their effects will be analyzed. Also the following risks will be addressed: electric shock to people, damage to pipeline insulating coating and insulating joints, and damage to pipeline cathodic protection system. Typical design criteria will be presented together with typical mitigation means and design best practices. Finally an application example will be shown.
Mr. Daconti has over 35 years of diverse power systems experience, with emphasis on electric power system planning, power system electromagnetic compatibility, and overhead transmission line design. His power system planning experience includes: interconnection studies for conventional and renewable generation in the US and abroad; compliance analysis regarding NERC and FERC requirements; and power flow, short-circuit, transient stability and electromagnetic transient analyses. His power system electromagnetic compatibility experience includes: analysis of electro-environmental disturbances caused by high voltage transmission lines; analysis of induced voltages on nearby parallel circuits, gas pipelines, and railroads; grounding and shielding systems design; and analysis of electric power quality disturbances. His overhead transmission line experience includes: electrical and mechanical studies required for conceptual and detailed overhead line design; environmental impact studies associated with high voltage lines; and several EPC activities associated with 69 kV to 500 kV AC power lines. Mr. Daconti is a co-author of two McGraw-Hill technical handbooks for engineers.
