COURSE OVERVIEW

 

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

This course is designed to provide participants with a detailed and up-to-date overview of power system, generation and distribution. It covers the main components of the power generation system and its functions; the block diagram of the auxiliary systems; the purpose of a gas or steam turbine; the function of turbine components and the starting sequence of a gas turbine; the turbine variables, controlled speed, pressure and temperature; and the meaning of excitation, the function of these auxiliary systems and why loads need to be shed and under what circumstances this would need to be done. 

 

This course will also cover the procedure and conditions for synchronizing two generators; drawing a block diagram of the excitation system and a line diagram indicating the protection requirements for a medium sized generator; the requirements and precautions for startup, synchronizing and generator loading procedures; the requirements of a design data sheet for a power generator; and the function of governors in different mode of operations. 

 

Further, the course will also discuss the steps necessary to put a generator on line and off load, how to increase the loading of a generator and the difference between load shedding and load sharing; the generator excitation system and the operation of the auxiliaries specifically for the turbine and generator; the control philosophy in relation to turbine, generator and auxiliaries; the purpose of an AVR/digital excitation control system and how it works; the safety measures that shall be taken before and after a high voltage test has been made on a generator; the tests that are done on a generator; the schematic diagram of the excitation system of an alternator; and preparing a data sheet for this equipment. 

 

During this interactive course, participants will learn the capability chart indicating the limitations;  how the reactive load is shared between generators connected in parallel; the startup, synchronizing and loading of a generator as well as the startup and shutdown of a turbine; how to put the load shed/share systems in operation and the data of the load sharing system; the testing of the generator protection system; the tests/checks to be conducted during maintenance;  the startup, synchronizing and loading steps of a generator being taken and why; the excitation system diagram explaining how this system works and the outcome when an alternator has lost its excitation when connected in parallel with others; and the effects of failures of any auxiliary systems.
