An introduction to computer programming Introduction: distribution system automation is built on 5 pillars which are computer programming, computer aided design & drafting (CADD), system supervisory & data acquisition systems (SCADA), local networks including LAN & WAN and geographic information systems (GIS) including global positioning system (GPS) software & receivers. Computer programming can be classified broadly into system programming & application programming. System programming is mainly concerned with the programming for the hardware components to get them to function as required i.e. writing drivers and hardware specific programs & software. Application programming involves writing the appropriate procedures to get the different computer elements to function in order, accept user input, to perform the appropriate calculations and to output the results in an easy & understandable fashion to the user. To program a computer, a computer programming language is used. Programming languages can be classified into: machine level (native language), low level (assembly language) and high level languages (eg. Fortran, Pascal, Cobol, Basic, C, C++, Visual Basic & C#). High level languages can be further classified into procedural or object oriented languages. Another way to classify high level languages is whether it requires a compiler or not, those languages that do not require a compiler are called script languages. Examples for script languages are Javascript, Tcl/Tk, perl & VBS. Certain languages (with or without their integrated development environment IDE) are only available commercially, others are available free of charge (just to be downloaded through the Internet). Certain languages (with their compilers) are suitable for cross platform, others have a version for each operating system (platform), example for operating systems are: Windows, Mac, Linux,.. In this guide, specific tasks to be performed and problems to be solved as part of a power system analysis process will be identified. The programs that solve for some of these tasks or problems will be given, written in more than one computer programming language. One example written in gtkmm is part of the electrical power systems distribution management information system (EPDMIS). To compile and run GTKMM under Windows, follow the following steps: 1) Download & install MingW. 2) Download & install DevCpp. 3) Download & unzip GTK library under c:\MingW. 4) Download & install gtkmm library under c:\DevCpp. 5) Download & install msys 6) Copy the source code into /home/user_name/ directory of C:\msys. 7) Compile source code, example for command line compiling statements in msys window: 1. export PKG_CONFIG_PATH=c:/DevCpp/gtkmm/pkgconfig 2. g++ 'pkgconfig –cflags gtkmm2.4' example.cc o example 'pkgconfig –libs gtkmm2.4' 8) Run executable (.exe) Windows file
The languages used are: QB, C++, VBA, VB.net, Pascal, SmallEiffel, GTKMM, Perl, TCL/TK, Python & JS. The basic functions that any programming language must offer are: user interface (interactivity) i.e. must accept user input at run time, must output results to the screen, must offer the facility that allows saving data & information to the hard drive (mass storage devices) i.e. saving inputted data & calculated ones for further referencing or printing, the language should provide means to allow decision making during program execution based on intermediate/calculated results as well as user input/response and finally it should allow for looping through the instructions/statements of a program. Saying Hello in different programming languages: Pascal: program hello; begin writeln('Hello world from Pascal'); end. SmallEiffel: class SIMPLE creation make feature make is do io.put_string("Hello from SmallEiffel.%N"); io.put_new_line end; end Active Perl: print "Hello from ActivePerl!"; Tcl: puts stdout {Hello from TCL/TK}; Tk: #exec wish "$0" $@" button .hello text "Hello from Tk" command { puts stdout "Hello from Tk"; destroy . } pack .hello Python:
print "Hello from the Python" Fundamental calculations in electrical power systems analysis: The fundamental calculations (i.e. tasks that the computer programs have to perform) can be any of the following: the calculation of the equivalent of a few series or parallel elements or branches, the conversion from wye to delta & vice versa, matrix manipulation, simultaneous equations calculations, per unit calculations, bus modeling and short circuit calculations for simple radial system. The other calculations involved in power systems analysis i.e. problems that must be solved are: short circuit calculations for radial (complex and with multiple feeders) and network (grid) systems, load flow calculations including losses evaluation for radial as well as network systems, reliability analysis, stability calculations, transients analysis and economical evaluations for the application and modification of power systems. Pascal: Example, calculating the equivalent of a few resistive or reactive parallel branches, converting wye to delta & vice versa: program test1 (input,output,fdata); var choice,noe,q:char; var el1,el2,el3,el4,el5,result,result0,result1:real; var fdata:text; var fname:packed array [1..12] of char; begin while (choice<>'q') do begin writeln ('enter a for equivalent of parallel elements, b for YtoDelta conversion'); writeln ('enter c for DeltatoY conversion & enter q to exit'); readln(choice); if choice = 'a' then begin writeln('number of elements'); readln(noe); if noe ='2' then begin writeln('first branch'); readln(el1); writeln('second branch'); readln(el2); result:=(el1*el2)/(el1+el2); writeln(result:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname);
rewrite(fdata); write(fdata,'result:'); write(fdata,result); close(fdata); end; if noe='3'then begin writeln('first branch'); readln(el1); writeln('second branch'); readln(el2); writeln('third branch'); readln(el3); result:=1/((1/el1)+(1/el2)+(1/el3)); writeln(result:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname); rewrite(fdata); write(fdata,'result:'); write(fdata,result); close(fdata); end; if noe='4'then begin writeln('first branch'); readln(el1); writeln('second branch'); readln(el2); writeln('third branch'); readln(el3); writeln('fourth branch'); readln(el4); result:=1/((1/el1)+(1/el2)+(1/el3)+(1/el4)); writeln(result:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname); rewrite(fdata); write(fdata,'result:'); write(fdata,result);
close(fdata); end; if noe='5'then begin writeln('first branch'); readln(el1); writeln('second branch'); readln(el2); writeln('third branch'); readln(el3); writeln('fourth branch'); readln(el4); writeln('fifth branch'); readln(el5); result1:=1/((1/el1)+(1/el2)+(1/el3)+(1/el4)+(1/el5)); writeln(result:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname); rewrite(fdata); write(fdata,'result:'); write(fdata,result); close(fdata); end end; if choice = 'b' then begin writeln('1n element'); readln(el1); writeln('2n element'); readln(el3); writeln('3n element'); readln(el2); writeln('12 element'); result:=(el1+el3)+(el1*el3/el2); writeln(result:4:2); writeln('23 element'); result0:=(el2+el3)+(el2*el3/el1); writeln(result0:4:2); writeln('31 element'); result1:=(el1+el2)+(el1*el2/el3);
writeln(result1:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname); rewrite(fdata); writeln(fdata,'element 1n, element 2n & element 3n, respectively:'); write (fdata,result:4:2,','); write (fdata,result0:4:2,','); write (fdata,result1:4:2,'.'); close(fdata); end; if choice = 'c' then begin writeln('12 element'); readln(el2); writeln('23 element'); readln(el1); writeln('31 element'); readln(el3); writeln('1n element'); result:=(el2*el3)/(el1+el3+el2); writeln(result:4:2); writeln('2n element'); result0:=(el1*el2)/(el2+el3+el1); writeln(result0:4:2); writeln('3n element'); result1:=(el1*el3)/(el1+el2+el3); writeln(result1:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname); rewrite(fdata); writeln(fdata,'element 1n, element 2n & element 3n, respectively:'); write (fdata,result:4:2, ','); write (fdata,result0:4:2,','); write (fdata,result1:4:2,'.'); close(fdata); end end end.

The languages used are: QB, C++, VBA, VB.net, Pascal, SmallEiffel, GTKMM, Perl, TCL/TK, Python & JS. The basic functions that any programming language must offer are: user interface (interactivity) i.e. must accept user input at run time, must output results to the screen, must offer the facility that allows saving data & information to the hard drive (mass storage devices) i.e. saving inputted data & calculated ones for further referencing or printing, the language should provide means to allow decision making during program execution based on intermediate/calculated results as well as user input/response and finally it should allow for looping through the instructions/statements of a program. Saying Hello in different programming languages: Pascal: program hello; begin writeln('Hello world from Pascal'); end. SmallEiffel: class SIMPLE creation make feature make is do io.put_string("Hello from SmallEiffel.%N"); io.put_new_line end; end Active Perl: print "Hello from ActivePerl!"; Tcl: puts stdout {Hello from TCL/TK}; Tk: #exec wish "$0" $@" button .hello text "Hello from Tk" command { puts stdout "Hello from Tk"; destroy . } pack .hello Python:
print "Hello from the Python" Fundamental calculations in electrical power systems analysis: The fundamental calculations (i.e. tasks that the computer programs have to perform) can be any of the following: the calculation of the equivalent of a few series or parallel elements or branches, the conversion from wye to delta & vice versa, matrix manipulation, simultaneous equations calculations, per unit calculations, bus modeling and short circuit calculations for simple radial system. The other calculations involved in power systems analysis i.e. problems that must be solved are: short circuit calculations for radial (complex and with multiple feeders) and network (grid) systems, load flow calculations including losses evaluation for radial as well as network systems, reliability analysis, stability calculations, transients analysis and economical evaluations for the application and modification of power systems. Pascal: Example, calculating the equivalent of a few resistive or reactive parallel branches, converting wye to delta & vice versa: program test1 (input,output,fdata); var choice,noe,q:char; var el1,el2,el3,el4,el5,result,result0,result1:real; var fdata:text; var fname:packed array [1..12] of char; begin while (choice<>'q') do begin writeln ('enter a for equivalent of parallel elements, b for YtoDelta conversion'); writeln ('enter c for DeltatoY conversion & enter q to exit'); readln(choice); if choice = 'a' then begin writeln('number of elements'); readln(noe); if noe ='2' then begin writeln('first branch'); readln(el1); writeln('second branch'); readln(el2); result:=(el1*el2)/(el1+el2); writeln(result:4:2); writeln('enter filname to save the data to:'); readln(fname); assign(fdata,fname);
