The Importance of considering transmission line losses on a power system is proven by determining the costs directly associated with losses on an actual system.This was done by determining the operating costs for a year’s time generating units remote from the load centers and comparing this to the operating costs for a year’s time with the same units located at the load centers.The savings that resulted for a system with a peak annual load of 2500 megawatts (MW) was $1,175,000 per annum or 3.5 per cent of the total annual operating cost.
To accomplish these results, a method for calculating transfer impedances and ultimately plant penalty factors using the voltage phase angle method is discussed and applied to a sample system. The advantages of the method are indicated.
