388-12 Voltage and Reactive Control VAR (1.5 CEH)
Learning objectives
- Identify the responsibilities associated with the Transmission Operator regarding voltage and Reactive Power Schedules
- Recall how Transmission Operators use surge impedance loading of a transmission line to monitor system voltage
- Identify which reactive resources are available to the Transmission Operator to help regulate voltage levels
- Recall how a Transmission Operator directs the operation of reactive resources in Real-time to regulate transmission voltage and reactive flow as necessary
- Explain the impact to system voltage when a high voltage transmission line is either placed into or taken out of service.
Course overview
North American Interconnections operate at 60 cycles per second. The connection between the current and voltage cycles relates to the voltage control on the Interconnection. That connection is the phase angle in a power system, which is the angular separation between the current and voltage cycles. Power systems exhibit three characteristics: resistive, capacitive, and inductive. Understanding these three characteristics is important to understanding power flow and voltage control. The Voltage and Reactive Control training course explains how to monitor, control, and maintain voltage levels, reactive flows and reactive resources to protect equipment and reliably operate the Interconnection. It describes the impact to system voltage when a high voltage transmission line is placed in service or taken out of service. This online course is part of the Active and Reactive Power training series.
