INTRODUCTION
This document describes the input parameters and the application of the simplified dynamic
model of the ALSTOM MICROREC K4.1 excitation system for the Cartegena KA26-1 ICC
single-shaft Combined Cycle Power Plant (CCPP). This model has been implemented using the Power
Technologies Inc., PSS/E program.
2.
MODEL APPLICATION AREAS
This model also includes the functionality of the over- and under-excitation limiters. Since this
model is only implemented using Laplace transforms it is therefore not suitable for PSS/E
extended term simulation that uses Z-transforms modeling.
3.
MODEL USAGE
This excitation system model is implemented as a user defined model in PSS/E. The DSUSR.DLL
library must be located in the directory where the PSS/E program is first started. The model
calling convention is the same as other PSS/E user defined models as documented in the
PROGRAM OPERATION MANUAL: VOLUME 1.
An example of data input for this model is shown in the Section 6.
Some comments to the model usage are given below:
•
To make a voltage reference step change the parameter VINJ must be set to 1. The
parameter INJ_PRRV is the step change to be made and is given in per unit. The time for
this step change to be initiated is given by the parameter TINJ. The voltage reference is
returned to the initial value after the time indicated by the TRESET parameter.
•
The parameter UPRIN prints out all the STATEs and VARs for each time step on the LPDEV
output device if this is set to 1.
•
The Power System Stabilizer (PSS) is automatically turned off when
- the electrical power falls below the parameter MINSP1 (in per unit on generator rating).
- the stator current falls below the parameter MINST1 (in per unit on generator rating).
