Protection & control systems are a critical part of the transmission & distribution systems that feed power to megacities & industries.
This course aims to introduce all of the basic principles associated with electrical power systems protection with examples.
I have tried my best to include a practical example from the field as I have 17 years of field experience in substations. I have included real examples, equipment nameplate, Single line diagram, real field examples.
The course will go into detail for the following key topics:-
· Introduce all of the key concepts of a protection system, power quality, reliability, fault & event recording.
· Show the basic principles behind electrical protection philosophy
· Explained cascade tripping, Comtrade files, how to localize the faults
· Look at step & touch potential concept, Voltage or Current which is lethal
· Why gravel is used in substation, How to protect equipment & human
· Look at Earth Leakage Relay, How it operates
· Understand protection philosophy, A)Selectivity. B) Sensitivity. C) Speed. D) Reliability. E) Simplicity. D)Economy.
· Relationship between selectivity and zones of protection. open & close zones, tele protection
· Look at Primary, backup & duplicate protection
· Look at relay classification, Electromechanical, Digital, Microprocessor & Numerical relays
· What are phase & ration compensation in transformer differential protection, interposing C.Ts
· How Over Current, Earth fault relay operates
· How Direction Overcurrent relay, Definite time & inverse time overcurrent relay operates.
· Understand Magnitude, differential & phase comparison principles
· look at the working principle of Breaker failure relay
· look at the basic electrical theory, Ohms Law, KVL, KCL, Calculate HV & LV rated & short circuit current transformer
· Introduction to the per-unit system, how to evaluate arc flash hazard using the per-unit system
· look at three-phase systems, balanced, unbalanced, three-phase fault, phase to phase fault, phase to ground fault
· Understand Symmetrical components
· Look at primary & secondary equipment, electrical wiring basics
· Understand Auxiliary relays, Main relays, Contactors
· Difference between Circuit Breaker & Isolator & Load Break Switch
· Understand the concept of interlocking
· Understand surge arrestor & surge counter
· look at GIS, AIF & MV SWGR
· Look at CB operating cycle, pole discrepancy, anti pumping, trip circuit supervision schemes.
· Intro to ANSI device codes
· Introduction to internal, external & through faults
· Look at Capacitor Storage trip units
· Show batteries & charger, how they work, Single Line Diagram of DC system, Single Line Diagram of Charger
· look at LCC, Gas diagram, Gas compartment, Gas permeable & Gas tight
· introduction to Relay Coordination
· Look at complete protection engineering cycle Design Phase, Manufacturing Phase, Shipment Phase, Inspection, T&C, Maintenance
· Look at three-phase currents and see how they can be broken down into sequence components and harmonics.
· Provide the basic principles behind current transformers, how they operate and need to be connected
· Show how voltage transformers operate and introduce the key types
· Go into detail on what happens when a fault occurs on the system
· Look into circuit breaker control and protection systems and how they interact with the protection systems.
· The main protection relay we will look at on this course is over protection. We go into detail on the basic and more advanced versions and show how this relay can be put to good use to provide great fault discrimination
· Look at the different types of earth fault relays and see how they can be used to protect some key equipment\s
By the end of the course, the student will be able to identify all of the key components of a protection & control system, understand how all of these components fit together to create a fully integrated system, protection fundamental concept, protection schemes & relays, battery charger & batteries.
