LINEAMPS LineAmps for all lines

Transcription

1 LINEAMPS New System of Dynamic Line Ratings Electrotech Enterprises LLC, USA

2 LINEAMPS New System of Dynamic Line Ratings Provides dynamic ratings of all lines in an electrical network Includes overhead and underground lines Forecasts hourly values of line Ampacity for a week in advance Runs autonomously Integration with Google maps for easy visualization of lines, line current, and site location information View of selected Burbank transmission line in Google map

3 LINEAMPS FOR UNDERGROUND CABLES Underground Cable Dynamic Rating LineAmps calculates Ampacity of all transmissions lines including transmission lines having both overhead lines and underground cables Underground Cable Dynamic Ratings includes duct bank model and mutual heating from adjacent cable circuits in the same duct

4 LINEAMPS FOR OVERHEAD CONDUCTORS Overhead Conductor Dynamic Rating Includes database of different types of conductors New conductors can be easily added to the database by user

5 VIEW LINES IN GOOGLE MAP Dynamic rating of all lines View geographic location of all lines in the electrical network View line Ampacity and conductor temperature by clicking on a line View location of transmission line sites and site data View weather stations and weather data by clicking on weather stations

6 AUTOMATIC AMPACITY CALCULATIONS Automatic Ampacity calculation of all lines are updated at each hour Real Time Updates: Normal Ampacity for steady state condition Dynamic Ampacity for short duration overload (30 min overload: Burbank example) Dynamic Ampacity for long duration overload (2 hr overload: Burbank example) Display Ampacity limiting site for each line (critical section) Now includes location of critical Site

9 STEADY STATE CALCULATIONS Overhead Conductor Temperature

10 STEADY STATE CALCULATIONS Overhead Conductor Ampacity

11 DYNAMIC STATE CALCULATIONS Underground Cable Ampacity

12 DYNAMIC STATE CALCULATIONS Underground Cable Time to Reach Max Temperature

13 DYNAMIC STATE CALCULATIONS Overhead Conductor Ampacity

14 TRANSIENT STATE CALCULATIONS Overhead Conductor Temperature Heating

15 TRANSIENT STATE CALCULATIONS Overhead Conductor Temperature Cooling

16 REAL TIME TRANSMISSION LINE OPERATION Time to Reach Critical Temperature These are real time calculations updated every 10 seconds

17 FORECAST AMPACITY LineAmps provides hourly values of line ampacity up to a week in advance, used for generation and transmission system planning. Just select a line from the list of lines and instantly view line ratings for a week in advance.

18 FORECAST AMPACITY Hourly values of line ampacity up to a week in advance are output to LineAmps database for access by external programs.
