Title: Applications



Studies involving the use of EMTP-RV - EMTPWorks can be put into two general categories. One is design, which includes insulation coordination, equipment ratings, protective device specification, control system design, power quality assessment, harmonic studies, etc. The other is solving operating problems such as unexplained outages or equipment failures. A partial list of typical EMTP studies follows:

EMTP-RV Advanced Practical Applications
  Switching surges
    Deterministic
    Probabilistic
    Single-pole switching
    High-speed reclosing
    Capacitor switching
    Transient recovery voltages
    Cable switching transients and sheath protection

Lightning surges
    Backflash
    Induced surges
    Incoming surges at stations

Insulation coordination
    Overhead lines
    Outdoor stations
    Gas-insulated substations
    Arrester duty


Shaft torsional stress
    Subsynchronous resonance
    Switching-induced

High voltage DC (HVDC)
    Controls
    Electrical transients
    Harmonics



Temporary overvoltages
Power electronics and FACTS (HVDC, SVC, VSC, TCSC)
General purpose electrical and electronic circuit simulations
Power quality issues
Carrier frequency propagation
Harmonics
Ferroresonnance
Distribution networks and distributed generation
Power systems dynamics and load modeling
Subsynchronous resonance and shaft torsonial stresses
Power systems protection issues
Series and shunt resonance

General control systems
Grounding
Asymmetrical fault current evaluation
Phase conductor transposition
Ground wire losses
Steady-state analysis of unbalanced systems
Capacitor bank switching
Series capacitor protection

This is only a partial list. One of the EMTP's major advantages is its flexibility in modeling; an experienced user can apply the program to a wide variety of studies.
