Distribution System Losses

01/31/2011 11:10 PM

I have been tasked to calculate the distribution system losses for our site, the site supply voltage is 22kV, 3P, 50Hz, AC. The metering is installed on supply side`s secondary.

I have been able to calculate the transformer losses from manufacturer`s test certificates and also know that the other losses can be calculated using P = I^2 R equation but bit confused as the system involves the 22kV suitable overhead lines and underground cables and 22kV ring mains.

Can anyone pls. advise in regards to the calculating the other losses, or refer me to the good references (book/internet links/etc)

Hi,

do you have any other meters installed?.. if you are talking about distribution losses, what kind of losses?.. technical or non technical loss?..

installing other meters to locations where you want the losses to be monitored is a good solution.

If you tried to solve it, it would be difficult, since losses changed over time. What you should calculate is kwhr loss..

all i could say is that.. i would since to install meters on those locations. if not.. why not do load flow studies on your system?..and use the sending voltages at your connection point then simulate the losses. (but you need an accurate model of your system)

God bless!!
