Introduction to Power System Operation and Control
www.kth.seVoltage Control Additional means are usually required to control voltage throughout the system: – sources or sinks of reactive power, such as shunt capacitors, shunt reactors, synchronous condensers, and static var compensators (SVCs) – line reactance compensators, such as series capacitors – regulating transformers, such as tap- changing
Research Roadmap on Grid-Forming Inverters
www.nrel.gov• Frequency control • Voltage control • System protection • Fault ride-through and voltage recovery • Modeling and simulation. The review both delineates contemporary advances and highlights open research questions that must be addressed to enable the widespread adoption of inverter-based resources across the grid.

files.danfoss.comThe control I/O-terminals are isolated from the mains potential. However, the relay outputs and other I/O-terminals may have a dangerous control voltage present even when VACON® NX is disconnected from mains. Before connecting the AC drive to mains make sure that the VACON® NX front and cable covers as well as the cabinet doors are closed ...
