Abstract
Voltage Collapse Risk Associated to Under-Voltage Capacitive Compensation in Electric Power System Operation
Highlights
In 2004 it was published in this journal a study[1] analyzing the procedure to maintain an adequate voltage profile through the connection of shunt capacitor bank into a load bus to avoid an under-voltage condition
When a constant power factor load growth is under analysis and the capacitor bank is included, there is a jump from a PV curve to another similar by changing the Thevenin impedance and source voltage (Zth and Eth)
The load bus voltage and some VC Proximity Indicators (VCPIs) were analyzed by simulation with the software MatLab SimPowerSystem using a numerical example
Summary
In 2004 it was published in this journal a study[1] analyzing the procedure to maintain an adequate voltage profile through the connection of shunt capacitor bank into a load bus to avoid an under-voltage condition. The capacitor was included in a Thevenin equivalent circuit that supplies the load bus. When a constant power factor load growth is under analysis and the capacitor bank is included, there is a jump from a PV curve to another similar by changing the Thevenin impedance and source voltage (Zth and Eth). The mentioned study[1] was very interesting, but it did not alert on the VC risk that can happen even with the load bus voltage within the permitted limits. This fact is emphasized in the present work which includes VCPIs and discussions about their application
