Abstract
Electrical distribution system faces various problems like reactive power burden, unbalanced loading, poor voltage profile and harmonic distortion. Dynamic power factor correcting apparatus is required to get uniform voltage for fast changing loads. The old installations at the distribution level are still operating with TSC-TCR systems. The TSC-TCR system, while correcting power factor, inject harmonics into the lines causing higher THD of the distribution line supplies at PCC. This paper proposes to optimize both the harmonics and reactive power injection into the system by the operation of TSC-TCR type SVC used in conjunction with fast changing loads at LV distribution level. Further it is proposed to provide user friendly approach to optimize either harmonic injection or reactive power or both together. This being a nonlinear problem Fuzzy logic system and ANN is used to get the solution. It is giving optimum triggering delay angles used to trigger switches in TCR. The various configurations discussed in the paper are attractive and can be used flexibly at distribution level.Keywords
