1 The System’s architecture
SICRE consists in a set of programs and data files.
Electric system files
Graphic pages files
SICRE’s programs
Input files
Internal file
Output files
Fig. 1: SICRE’s structure
In fig. 1 it is represented the data file structure of SICRE:

the electric system’s files contain the data of the electric system: they are organized in different
ASCII files. It contains the network topology, the parameter of the mathematical models and the variable data of the load-flow situation; most of the files are supplied by other programs; some of them
are prepared by the user with the help of SICRE.

the graphic pages’ files contain the description of the graphic pages (network scheme, function of
time diagrams): they are used to display the electric system and to execute manouvres in the simulation. They are text files prepared using the SICRE’s graphic configuration program.

the internal file contains the data of the electric system and other data in a structured binary form
(database) that is directly accessible by the programs.

the output file contains the files prepared by SICRE: they can be read by the user, managed by
SICRE or by external programs (i.e. imported in electronic sheets).
SICRE’s programs act contemporary or one for time and execute the followings:

read input file and creation of the internal database

automatically generate the input files in the SICRE format

prepare and modify graphic pages

simulate transients and animate the graphic pages

perform the electric system analysis

supply other services
2
CESI
There are two ways to use the programs:

batch: it is the common way to activate the program from a UNIX shell terminal: it reads the data
files (standard input and other files), elaborates the data with the help of the user if necessary by typing directly on the prompt and prepares the output files (standard output and other files);

client-server: it is the way to allow a set of programs or processes to operate in a concurrent mode.
In the description of the programs are reported the allowed modalities.
The organization of the simulation environment is composed by two environments:

the system environment: it consists of a directory (the system directory) which contains the executable files of SICRE, the on-line documentation and help, and other files for the configuration of the
workstation.

the user’s environment: it consists of a directory (user directory) which contains all the data files
for a specific electric network and some customized procedures. One or more directories may exist
on the same workstation.
The system directory is created, at installation time, by a particular user, the SICRE manager, which is responsible for the installation and the updating of the software. Normally the system’s files should not be
modified by the users.
The user directory is created by a user of the simulation station: he creates the input files and is responsible
for the configuration for a use correct use of the system environment.
2 Data files
1.1.
Input files
The input files describe the electric system topology, the models (models’ parameters) and the graphic pages.
They are a set of files in ASCII format, supplied by other systems (i.e. CRESO or SPIRA) or automatically
generated by SICRE.
The input files are divided into:

fixed data files which contain the fixed data of the entire electric system: of the real and of the
equivalent part;

situation file which contains the foreground data of the electric system;

pages’ files which contain the data for the graphic pages;
2.1.1 FIXED DATA FILES IN THE DADIR FORMAT
It contains the physical data of the electric system (of the real and of the equivalent part) in a standard format
called DADIR /1/.

Tab. 3 fixed data files in SICRE format
All the files are created by the user who should collect from qualified sources the requested data and insert
them using a text editor. The SICRE program acq helps the user preparing the files with standard data in the
correct format. Some of this data are extracted from the DADIR file, the other are deduced by the specific
experience. The user must verify the correctness of automatically created data and modify them if they are
not correct.
The tables 1, 2 and 3 are available in any configuration file of fixed data if it is created automatically by the
acq program.
2.1.3 Situation data file in DAVA format
The situation file contains the variable data of the electric system for a load-flow and it is used by SICRE to
initialize the simulation.
The file is a unique ASCII text in DAVA /4/ format and contains all the variable data for the components of
the DADIR file. It contains the data for: AREA, CD, IDR, IPLT, LINE, MAR, NAZ, NODE, POLO, SR,
TER, TPLT, VM, VSEC, XFM2, XFME.

2.1.5 Pages’ file
The pages file contains the data for the description of the graphic pages.
Each page is described by a file that contains dimension, position, color of the element present in the page.
The files are in text format but are modified only by the SICRE’s graphic editor cnf.
This format is not documented.
2.2 The database
The database contains the data of the electric system and the data for the graphic visualization. It is stored in
a file and it is loaded into memory during the simulation by the database allocator program which lets other
programs to use it.
2.2.1 The database’s files
The database consists of two files normally present in the work directory:

the main database (i.e. sicre.db) contains the data of the electric system: the fixed data and the situation data; the situation may be the initial situation (i.e. from the load-flow) or the final situation obtained by the simulation; in the latter case the database contains also the sampled transient of the variable in evidence.

the database of the variables in evidence (i.e. evi.db) contains the data to build the function of time
diagrams of the variables in evidence that is the variables (voltages, currents, ...) which are sampled
and stored during the simulation.
It is possible to have in the same work directory two or many main databases (with different names) which
contain different situations. Each of them (together with only one database of the variables in evidence) may
be used as a starting point for the simulation or for other activities.
When the database is allocated in the memory by the database allocator program or by another program, it is
organized in such a way to permit direct access and controlled access by the shared database. Some programs
permit to the user the direct access to the shared database (see the VAR directive of the programs sim and
dbe). The program cnf, during the creation of a page, lets the user assign any variable of the database in order to display its value or to build the function of time diagram. For this it is necessary to know the structure
of the database and the description of the contained variables.

CESI
Each element of an array is a structured data and describes an element of the electric system.
Inj is an array of data for all the injectors of the electric system (units, loads)
Inj.BRTX45 is a structure of data of the injector with code BRTX45
Inj.#23 is a structure of data of the injector in position 23 of the array
Inj.BRTX45.P is the value of the active power (MW) of the injector with code BRTX45
Other variables those may be interesting for the user are (* stands for the code of the element):

Inj.*.Cod code of injector’s identifier

Inj.*.P active power injected by the injector (MW)

Inj.*.Q reactive power injected by the injector (MVAr)

Brc.*.AT.P transit of active power at the first end of the branch (MW)

Brc.*.BT.P transit of active power at the second end of the branch (MW)
Remark: the injected power are positive if they are generated for injectors like generating units and capacitors, while they are positive if they are absorbed by loads.
2.3 OUTPUT FILES
It is the set of files those are prepared by different programs of SICRE: they may be read by the user or are
elaborated by the programs of SICRE or by external programs (i.e. by electronic sheets).
The output files are described with the description of the programs they refer to.
7
CESI
3 Programs’ manuals
SICRE is formed by a set of programs those may be activated in different ways:

directly from the command line of a UNIX terminal specifying all the parameters and the options

from the customized procedures contained in the work directory

from other programs of SICRE
The following remarks are generally valid:

a program, activated by terminal without parameters, gives a quick help about its name and version,
a description of its main features and of the parameters on the command line, the list of the input
files, output files and working files.

some programs, those are activated from the terminal, ask specific questions (conversational interaction): the answer can consist in a single line statement followed by <RETURN>. Usually a standard
answer is provided for.

some programs have a conversational interaction with a “command modality” like the UNIX shell.
They present a prompt to which answer with a command followed by parameters (usually called “directive”). One of the command is the directive “HELP” that gives the list of the directives.

almost all the programs use the electric network’s data so using the network’s database. In the batch
modality the first parameter of the command line is the name of the database. In the client-server
modality the first parameter of the command line is the “-online” option that must be supplied as an
alternative to the name of the file of the database. In the latter case it is necessary to activate the database allocator (smm) before the activation of the client.
In the following there is a view of the manuals of the programs of SICRE. They are part of the on-line documentation of SICRE.
3.1 ACQ - Data acquisition
It is the data acquisition program for the network’s input files and it creates the network’s database.
It is a batch program and it is possible to activate it directly from the command line (specifying all the parameters) or via a customized procedure (i.e. xa).
The program acq without parameters gives the following text:
8
CESI
Syntax : acq [ -online | filedb ] [options]
It acquires the data of the net archive and prepares the database named filedb
Options :
-f filefix it acquires the fixed data of the net.
The list of the data files is read form the configuration file named
filefix.
If the file does not exist it is automatically created with an interactive
procedure.
It creates the database file named filedb or, if it exists, covers it.
It deletes, if they exist, the database of the pages an the database
of the registered variables.
After having been acquired the net fixed data, all MMI pages must be
compiled with the lnk program.
-dpr (default) during fixed data acquisition reads protection data in DADIR
format
-spr
during fixed data acquisition reads protection data in SICRE format.
-s filesit
it acquires the variable data of a load situation.
The list of the data files is read form the configuration
file named filesit.
If the file filesit does not exist, it is automatically created
with an interactive procedure.
It updates the file named filedb.
-r filereg it acquires from file filereg the data of the registered
variables and append they to the existing in the data base
-xr
it erases all the registered variables and the transient
-xt
It deletes the transient and resets to zero the current time
leaving the situation unchanged.
-online the program is used as a client of the shared databas.
The option is an alternative to the name of the database file.
The acquisition of the fixed data (option “-f”) and of the situation (option “-s”) can be executed at the same
time (if “-f -s” is specified) or in two different times (specifying first the “-f” option). If there are two or
many different initial situations and the corresponding configuration files, the activity for the acquisition of
the situation updates the database substituting in case the previous situation.
The options “-online”, “-t” and “-x” are not useful for a standard use of the program.

CESI
3.2 SIM - Simulation of the transient
The program sim execute the simulation of the transient caused by a sequence of perturbations on the electric
system manually executed by the user or automatically generated by the intervention of the protections. The
transient is automatically computed starting from the situation that has been memorized in the network’s database; the transient lasts for a time decided by the user. The final situation may be memorized and used as
initial situation for a new simulation.
The program can be activated in two different modalities:

batch: the program loads the initial situation from the database file and receives the directives for
the simulation from keyboard; this modality is used for batch simulations with off-line analysis.

client: the program uses the database from the shared database and receives the directives for the
simulation from keyboard; this modality is rarely used;
The user has two ways to execute a simulation;

activate sim in batch modality giving the directives from keyboard

use the graphic interface and all the graphic objects to control the simulation (traffic-lights, breakers,
masks);
In the first case the user must know the directives, their parameter, the identifiers of the network elements to
do the perturbations on; this approach is suggested only for special cases.
In the second case the use is simpler and the simulation may be followed on-line using the same graphic interface; the directives are assembled by the graphic interface in a completely transparent way then they are
transmitted to the program sim that executes them; this is the common approach.
The knowledge of the directives is necessary in the case of a scheduled simulation. One of the directive is the
command “SCHED” followed by a file name. It allows to schedule a complete simulation that is it lets a sequence of directives, contained in the file, be activated. For a scheduled simulation is necessary that, before
the simulator is activated, the user prepares a file with an exact sequence of all the directives. After that, it is
possible to schedule the file from the traffic-light menu with the command “schedule simulation”.
Executing the program without parameters it gives the following text:
Syntax: sim filedb [filedat] [-out] [-trk FileName] [-cmd FileName] [-log FileName]
It executes the simulation of the transient starting from the situation
relative to the database filedb and according to the directives given by
keyboard or possibly by filedat.
In addition to the simulation directions other directives are available
for the analysis and the modification of the database.
The information about the available directions can be obtained using the HELP
direction.
The simulation is executed in a 'off line' modality i.e. using a local data base.
The program produces the following output files in the working directory:
- sicre_sim.log (trace of the events)
- sicre_sim.trk (additional information)
When the program is activated by the Simulation Control Panel it
produces the following output files in the working directory:
- sicre_sim_server.log (trace of the events)
- sicre_sim_server.trk (additional information)
10
CESI
Option:
-log FileName it specifies the file name containing the 'trace of the events'
-trk FileName it specifies the file name containing the track of output events
-cmd FileName it specifies the file name containing the track of intput events
-out
it activates the logging of the whole transient in the text file named
sim.out
Remarks for an advanced use of sim:
- The Simulation Control Panel activates the simulation program
in background with the command: $ sim -server
In this case the simulation directions are given only by the user
interface.
Here the list of the directives is reported: all the directives can be used in the schedule. The following text is
part of the on-line documentation of the program.
3.2.1 List of the directives
Let's have an overview on the commands of sim. They are used for executing and controlling the simulation
of the transient. They can be used in one of the following ways:
