Abstract

An SVC is proposed as a reactive power compensation device to suppress the rise in the customer voltage due to photovoltaic power generation systems. The SVC produces a reactive power by controlling a thyristor. The effect of the SVC on the rise in the customer voltage has been investigated. Calculation results show that installing an SVC on the low-voltage side is more effective for suppressing the rise in the customer voltage compared to an SVC located on the high-voltage side. As far as the calculation conditions are concerned, it is found that the rated capacity of the SVC needed to maintain the customer voltage within 101 ±6 V is over ±11.1 kVA. The slope reactance required to suppress the customer voltage lower than 107 V is found to be under 1.28%.
