Protection and Control of High Voltage Power Circuits
What you'll learn
- Here we deal with the protection & control principles of high voltage stations. HV Bus Differential Protection is studied along with restrictions due to CT saturation & mis-match and its solution, “Restraint Differential Protection”.
- System Faults; Switchyard Configuration & Elements; The DESN Station (Duel Element Spot Network); HV Bus Differential Protection; CT Saturation & Mal-operation of Bus Protection; CT Saturation & Restraint Differential Protection; Westinghouse KD - 4 Relay; Surge Protective Devices; Fuses; DC Protection; Logic Differential Protection; The Modern IED Relays (Intelligent Electronic Device); Overview HV Circuit Breaker Types (Oil, Vacuum, Air Blast, SF6); HV Circuit Breaker Controls (Closing & Tripping); HV Circuit Breakers; Reclosing (Syncrocheck CUH 90 – VG Relay); Dynamic Monitoring Equipment (DME); Impedance Relaying (POTT)
- A solid background in electrical circuitry.
Here we deal with the protection & control principles of high voltage stations. HV Bus Differential Protection is studied along with restrictions due to CT saturation & mis-match and its solution, “Restraint Differential Protection”.
Starting with System Faults and how they affect Switchyard Configuration & Elements simple “Differential Protection” is examined along with the mal-operation due to CT saturation and mis-match.
High Voltage Circuit Breakers are examined as to the various Types (Oil, Vacuum, Air Blast, SF6), their Controls (Closing/Tripping/anti-pumping) Reclosure Syncrocheck relay CUH 90 – VG as well as Breakers Failure Protection is part of this module along with a quick look at Dynamic Monitoring Equipment. Transfer & remote tripping along with the need to provide immunity from ground rise potential and open circuit situations.
