Über dieses Buch

The contents of this book are intended for those concerned with the simulation of the performance of generation systems. The subject is of importance to practising electrical engineers because of the many situations that arise in the design and operation of modem electromechanical systems and electrical power systems. The simulation programs contained in this book cover the prediction of generator performance for both large and small scale units. Synchronous generators of the round rotor and salient-pole variety of ratings of between a few Megawatts to around 1200 MW are invariably used by public supply companies for the generation of electrical power. For industrial purposes a variety of types of generator are used, including steam and gas turbines, and medium to low speed diesel engine driven generators, the former for those cases where process steam is available and the latter often in the role of marine generation or in a standby role.

1. Introduction

Abstract
The contents of this book are intended for those concerned with the simulation of the performance of generation systems. The subject is of importance to practising electrical engineers because of the many situations that arise in the design and operation of modern electromechanical systems and electrical power systems. The simulation programs contained in this book cover the prediction of generator performance for both large and small scale units.

2. Overview of system component modelling

Abstract
This chapter describes the mathematical representation of the various components of the generation systems considered. Equal consideration is given to both the electrical and mechanical aspects of the simulation. This is a basic requirement since an inaccurate response from the prime-mover system would inevitably lead to inaccuracies in the overall response.

3. Program operating manuals

Abstract
The three programs, for the steam, diesel and gas systems, have many common features. These are described in this section. The specific details unique to each individual program are described in chapters 4 to 6.

4. Steam turbo-generator program manual

Abstract
This program provides comprehensive dynamic analysis of a steam turbine driven three phase synchronous generator connected to an infinite bus through a generator transformer and either one transmission line or two transmission lines in parallel. Full electrical and mechanical dynamic response is obtained for a variety of user selected disturbances. Only one type of disturbance can be analysed in any program run. The disturbance options are:
1.
Steady state operation (no disturbance).
 
2.
System bus voltage change.
 
3.
AVR reference change.
 
4.
Governor reference change.
 
5.
Short circuit faults at a user-selected point on a transmission line,
(a)
three-phase-to-earth fault,
 
(b)
line-to-line-to-earth fault,
 
(c)
single line-to-earth fault.
 
 
6.
Line switching.
 
7.
Load rejection (including rapid closure of steam valves).

5. Diesel-generator program manual

Abstract
This program provides comprehensive dynamic analysis of a diesel engine driven three phase synchronous generator connected through a delta/star (Dy11) transformer to a load busbar, to which an induction motor can be connected. Full electrical and mechanical dynamic behaviour are simulated by the use of validated models under a variety of user-selected disturbance events. All types of short circuits and motor switching operations can be selected, with up to six events possible in any one simulation run. The event options are:
1
Short circuit faults at the generator bus,
a
single-phase-to-earth,
 
b
line-to-line,
 
c
three-phase.
 
 
2
Short circuit faults at the load bus,
a
single-phase-to-earth,
 
b
line-to-line,
 
c
three-phase.
 
 
3
Clear fault.
 
4
Connect induction motor.

6. Gas turbine-generator program manual

Abstract
This program provides comprehensive dynamic analysis of a gas turbine driven three phase synchronous generator connected through a delta/star (Dy11) transformer to a load busbar, to which an induction motor load can be connected if required. Full electrical and mechanical dynamic behaviour are simulated by the use of validated models under a variety of user-selected disturbance events. All types of short circuits and motor switching operations can be selected, with up to six events possible in any one simulation run. The event options are:
1
Short circuit faults at the generator bus,
(a)
single-phase-to-earth,
 
(b)
line-to-line,
 
(c)
three-phase.
 
 
2
Short circuit faults at the load bus,
(a)
single-phase-to-earth,
 
(b)
line-to-line,
 
(c)
three-phase.
 
 
3
Clear fault.
 
4
Connect induction motor.
