A new approach to control coordinated voltage in radial distribution feeders
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 1
Abstract
This paper deals with various aspects of coordinated voltage control in radial distribution feeders that are a type of electric power systems. At first we introduce an abstract of the paper and tutorials on voltage control and the search methods. Then we deal with the coordination of cascaded tap changers in radial distribution feeders. Unnecessary operations of the tap changers and consequently unnecessary wear as well as poor voltage quality are the result of poor coordination. A tuning rule for the local controllers as well as two new centralized schemes is proposed. We implement some simulation and result based on load patterns recorded during different seasons show that when tuned according to our recommendation, tap changers perform some 13 % fewer operations compared to when the present tuning is in use.
