An Evaluation of Large Scale Distribution system Unbalance |
| Abstract |
It is necessary to calculate the system"s factor for reasonable operation and security enhancement of large scale distribution system. This paper presents an effective three phase load flow calculation for distribution system unbalance evaluation. It takes into account an untransposed transmission line, the core loss as a function of voltage on the secondary side of the transformer, and a generator unbalance model which is also suitable for a salient pale machine. The load flow algorithm is used Newton-Raphson method of load flow equations in bus phase voltage. |
