A REGULATOR FOR FEEDER LINES SUITABLE FOR INDUCTION MOTOR LOAD AND INDUCTION GENERATOR SOURCE

摘要

A regulator for feeder lines suitable for induction motor load and induction generator source characterized in that it comprises a series reactor (L1) of value 0.25 to 0.40 per unit reactance, a plurality of shunt reactors (L2.L3) having value between 0.25 to 0.40 pu, working in a closed loop with a plurality of capacitors (C1- C7) and an electronic controller wherein said shunt reactors (L2, L3) and said capacitors (C1-C7) are adapted to be switched on/off when output voltage Vo is beyon the desired normal voltage Vnom + 5% and when output voltage is less than Vnom-5%, a decoder counter is adapted to count up and switch on capacitors till Vo comes within said desired normal voltage limit, and wherein a decoder counter is adapted to count down when Vo exceeds Vnom+5% till Vo is within said desired normal voltage limited and wherein said output voltage is adapted to remain regulated within said desired normal voltage limits irrespective of input voltage variation from-30% to 20% and load variation from no load to full load.
