System reliability indices deal with the adequacy of overall system supply and indicates behaviour response. The index express interruption statistics in terms customers which can be an individual, firm, or organization that purchases electric services at one location under rate classification, contract schedule. include: Average Interruption Frequency Index (SAIFI), Duration (SAIDI), Customer ...

optimal sitting and sizing of shunt capacitor banks at the distribution networks for the purpose of power quality improvement is drawn much attention of electric power utilities in the last decades. determining the optimal number, location and sizing of capacitor using bee colony optimization algorithm (bco) is being presented in this paper. the bco algorithm is a new population based meta-heur...

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...
