Why does Feeder Automation (FA) cause simultaneous operations of switches in multiple lines?

Feeder Automation (FA) and Under-Frequency Load Shedding (UFLS) are two critical protection and control mechanisms in power systems. While both aim to ensure safe and stable system operation, they carry potential conflicts in logic and timing that require careful coordination.Feeder Automation (FA): Primarily addresses local feeder faults (e.g., short circuits, ground faults) in distribution networks. Its objective is to quickly locate and isolate faulted sections and restore power to non-faulte

Will the small-current grounding line selection device be replaced?

A substation without a grounding line selection device experienced a single-phase grounding fault. The fault location system (FA) pinpointed the fault section between switch A and switch B. On-site patrol and handling took 30 minutes to isolate the fault, with no need for trial tripping of non-faulty lines.The coordination between the main network and distribution network relies on a comprehensive analysis of "bus protection action, 3U0, three-phase voltage + line terminal alarm". Based on exist

Short Circuit Ratio of a Synchronous Machine

The Short Circuit Ratio (SCR) of a Synchronous MachineThe Short Circuit Ratio (SCR) of a synchronous machine is defined as the ratio of the field current needed to generate rated voltage under open-circuit conditions to the field current required to sustain rated armature current during a short-circuit condition. For a three-phase synchronous machine, the SCR can be derived from its Open-Circuit Characteristic (O.C.C) at rated speed and Short-Circuit Characteristic (S.C.C), as illustrated in the

What is Static VAR Compensator (SVC)? Circuit & Operation in PF Correction

What is a Static VAR Compensator (SVC)?A Static VAR Compensator (SVC), also termed a Static Reactive Compensator, is a critical device for enhancing the power factor in electrical power systems. As a type of static reactive power compensation equipment, it injects or absorbs reactive power to maintain optimal voltage levels, ensuring stable grid operation.An integral part of the Flexible AC Transmission System (FACTS), an SVC comprises a bank of capacitors and reactors controlled by power electr

Regenerative Braking

Regenerative BrakingIn regenerative braking, the kinetic energy of the driven machinery is harnessed and fed back into the power supply mains. This braking mechanism comes into play when the driven load or machinery compels the motor to operate at a speed exceeding its no - load speed while maintaining constant excitation.Contents Applications of Regenerative Braking Regenerative Braking in DC Shunt Motors Regenerative Braking in DC Series MotorsUnder the conditions of regenerative braking, a si
