Case 3: Traditional Volt/VAR ManagementSubstation LTC orVoltage RegulatorsLine VoltageRegulatorCapBankLine VoltageRegulator1phXFMREndCustomerGeneration & TransmissionDistributionConsumptionVoltageTargetDistance from Substation‣ Optimized planning for placement of Regulators and Capacitor Banks – Cyme‣ Adding capacitor banks to the system further flattens the voltage profile‣ Benefits– Minimize/avoid voltage violations– Improve efficiency by reducing “average voltage”– Improves power factor– Frees up generating capacity by injecting VARs; reduced generation16
Case 4: Integrated Volt/VARSubstation LTC orVoltage RegulatorsLine VoltageRegulatorsCapBankLine VoltageRegulators1phXFMREndCustomerGeneration & TransmissionDistributionConsumptionVoltageTargetDistance from Substation‣ Optimized planning for placement of Regulators and Capacitor Banks – Cyme‣ With Integrated Volt/Var (IVVC), regulators, load tap changes and capacitorsare continuously monitored & controlled to manage power factor and voltage‣ Additional Benefits– Volt/VAR is optimized in real time for power quality and system efficiency– Utilities can perform Conservation Voltage Reduction to shed load - 1%reduction in voltage = 0.5-0.7% reduction in load17
