Abstract

OLTC (On-Load Tap Changer) has been widely used as an effective means to improve the voltage quality and reactive power distribution in power grid. This paper focused on the influence of OLTC tap regulation for voltage and reactive power distribution, and proposed the index of voltage effect per tap and reactive effect per tap to measure the changes of voltage and reactive power quantitatively. Based on these indices, a strategy about OLTC disposition in transformer substation and tap regulation is proposed, aim at solving the problem of irrational allocation of 500 kV OLTC.
