Load and Harmonic Forecasting for Optimal Transformer Loading and Life Time by Artificial Neural Network

Proper operations of transformer have several issues such as; preventing ofunscheduled removal’s, increasing of reliability and continues supply of consumerdemand. This result would be obtained that load and harmonic orders of sensitivitytransformer at intervals appropriate for next hours and days is predicted to by selecting optimal utilization coefficient, reduction life of transformer is prevented. Apossible solution for load and harmonic orders forecasting is implementation ofheuristically algorithm and method such as Artificial Neural Network (ANN). In thispaper, firstly relationship between transformer loss and life and effect of harmonicon its, is evaluated. Then by ANN method, load and harmonic orders of 400KVAdistribution transformer is predicted. Then by using of existing standards andprograms written in MATLAB environment Load ability or optimal utilization coefficient and life of transformer is calculated.
