Powerline Ampacity System: Theory, Modeling and Applications by Anjan K. Deb

By Anjan K. Deb

Civilization's calls for for electrical energy keep growing, but environmental, regulatory, and monetary constraints frequently hinder the development of latest energy vegetation and transmission traces. The problem now confronted via engineers, gear brands, and regulatory companies is to discover how you can maximize the potential of present strength lines.Powerline Ampacity approach is step one in assembly that problem. besides constructing an entire idea of transmission line ampacity, the writer makes use of object-oriented modeling and professional principles to construct an influence line ampacity method. He describes new transmission line conductor applied sciences and tool electronics evidence units which can take complete good thing about a dynamic line score procedure. He deals examples that basically express the industrial good thing about working an interconnected transmission community that has a various mixture of electrical energy new release assets. He additionally discusses - with examples - generator balance enhancement via dynamic line score.

A three-dimensional conductor thermal model is used to calculate conductor thermal gradient (Deb, 1998a, 1998b). An important contribution of the new line ampacity system is the ability to selfgenerate hourly values of weather data from statistical and analytical models, eliminating the need for real-time weather data on a continuous basis.

4 DYNAMIC AMPACITY The transmission line conductor is assumed to be in the dynamic state when there is a short-term overload on the line due to line energization or a step change in load. The duration of such overload condition is generally less than 30 minutes. In the dynamic state, the heat storage capacity of the conductor is considered, which allows 1306/C03/frame Page 37 Saturday, May 27, 2000 10:15 AM Theory of Transmission Line Ampacity 37 higher than normal static line loading to be allowed on the line for a short duration.

For example, it is well known that electricity demand depends upon weather conditions. 4 Power line conductors with fiberoptic cable. , 1991). , 1991) and wind speed (Hall and Deb, 1988b). 10) Z(t – 1), Z(t – 2) = difference of measured and predicted temperature at time (t – 1) and (t – 2) respectively A1, A2, A3, A4, A5, A6, A7 are the coefficients of the model ω = 2π/T = fundamental frequency T = 24 hour = period In the LINEAMPS program, Fourier series models of ambient temperature and wind speed are used to generate weather data.
