Requirements for upgrading from version 3.3 to version 3.4
Plant Signals
The essential plant signals are:
- Air-gap search coil voltage
- MW and MVAR loads.
- Once per rev. 'shaft marker'
Reliable MW and MVAR signals are now essential. The hardware for version
3.3 provides terminal blocks for 0 - 5 V inputs for these signals. For the
MVAR signals, a + 5 V range is acceptable. The field current signal on
some installations must be replaced by a MVAR signal. The RSTM Reference
Manual (section 5) for v3.3 details the terminal block numbers to be used in the
Terminal Connection Box (TCB) supplied with the original equipment.
The ‘shaft marker' is usually available from the shaft vibration
measurement system, but a signal derived from the generator terminal
voltage may be used. A reliable signal is needed to distinguish one pole
from the next, otherwise any shorted turn reports can appear to move
from one pole to the next for v3.3, and appear on more than one pole for
the same coil in v3.4.
Configuration Data Files
Several of the configuration data files (the files stored in the
directory, c:\data of the PC hard disc) need to be updated for the
upgrade to v3.4. The upgrade includes the revision of all files as
needed. Existing files may be sent to Siemens on floppy discs or as an e-mail
attachment, in compressed form.)
The Supervisory Program
The features of the revised Supervisory Program are illustrated by the
screens of information which are presented to the operator. Most of
these are shown in the DEMO.
Upgrade - Scope of Supply
- Version 3.4 of the Supervisory Program, rotsho2.exe*.
- Complete set of revised configuration data files, required for version 3.4*.
- Sections from the RSTM Reference Manual for v3.4:
- Section 3 - Operational Procedures
- Section 4 - Fault Detection and Rectification
- Appendix F - Program and Data File Descriptions
- Software Licence for 2 or 4 generator units.
- Rotor Shorted Turn Monitor - Data Requirements Documentation (a document which
summarises the customer's data after revision).
*Items 1 and 2 are supplied on floppy discs with instructions for
installation on the customer's PC.
The upgrade from version 3.3 to 3.4 is no longer available. The infomation
on these pages is provided for users of version 3.4 of the Siemens RSTM worldwide.
