Introduction to Industrial and Distribution System Transients and Applications of EMTP-ATP

April 24, 2017 @ 8:00 am - April 25, 2017 @ 5:00 pm

Industrial and medium voltage distribution systems encounter transients and abnormal conditions during their operating life cycle. While steady state analysis is an essential tool for system sizing and initial design and operation, awareness of system transients and abnormal conditions is paramount during both the design and operation of such systems. The Electro-Magnetic Transients Program (EMTP) is a powerful time-domain-analysis tool that can be utilized by engineers involved with industrial and distribution systems encounter. Due to prudent design of equipment, diverse system configurations and increasing awareness of the necessities of safe system operations, it is important for industrial and distribution electrical systems engineers to investigate voltage and other system transients and abnormalities.

This tutorial includes an introduction to industrial and distribution system transients topics such as:

  • Transient Recovery Voltage (TRV),
  • Capacitor Switching,
  • Large Motor Capacitance/Reactance Starting,
  • Ferroresonance in Potential Transformer (PT) and distribution transformers,
  • Induction in fences and pipelines parallel to a long run of overhead line,
  • Harmonics in Distribution Systems, and
  • Other relevant applications.

The tutorial will introduce the EMTP/ATP and the associated ATPDraw preprocessor. Development of ATP began in 1984 as an alternative to the impending commercialization of EMTP by BPA and its partners (DCG and EPRI). Participants will benefit from the hands-on portion of the tutorial to familiarize attendees with the software by developing examples using these tools.
