Learn Generator Single Line Diagram and Trip Matrix

Description

Welcome to the course of “Mastering Generator Single Line Diagram and Trip Matrix”. In power engineering, a single-line diagram (SLD), also sometimes called one-line diagram, is a symbolic representation of a three-phase electric power system.

The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and conductors are shown by standardized schematic symbols. Instead of representing each of three phases with a separate line or terminal, only one conductor is represented.

Whenever it comes to start new project, define scope of work, Single line diagram is always the most important document to consider & prepare. Furthermore single line diagram is also required to prepare shutdown / maintenance method statement.

Generator Single Line Diagram is most unique, in this training I will explain SLD & trip matrix of power plant. Tripping for power plant is complex there are so many options to select from various tripping command. Here we are talking about very large generator of 400MWs, we will discuss all possible tripping from protection systems of Gen-Power Transformer, Aux Transformer, Generators & excitation system. We will also discuss why certain components are issuing trip in a particular situation. For example why Generator differential protection is only giving tripping to generator circuit breaker & SEE/SFC. We will go through the trip matrix.

Following topics are covered in this training:

· Introduction to Single Line Diagram

· Three Line Diagram

· What is difference between single line and three line diagram

· How to represent different element in Single line Vs three line diagram

· Review Generator Single Line Diagram

· Concept of Generator, Generator Step Up transformer, Turbine, Auxiliary Transformer

· Tripping through Generator differential protection

· Zone of differential protection

· Tripping through Rotor earth fault protection

· Tripping through Stator earth fault protection

· Tripping through impedance Protection and its zone

· Tripping through reverse power protection

· Tripping through under excitation, unbalance, out of step

· Tripping through under frequency, Over frequency, Over voltage

· Tripping through breaker failure of generator circuit breaker

· Tripping through Inadvertent energization

· VT MCB Trip function

· CBF function

· Tripping through Over Excitation

· Tripping through Aux Over Current, Earth fault

· Tripping through Generator transformer mechanical protections

· Generator Over load

· Tripping through over current protection of excitation transformer

· Tripping through over current earth fault generator protection

· Tripping through impedance protection of generator transformer

· Tripping through differential trip of aux transformer
