lfgauss.zip193k08-02-12File is not ratedLFGauss1.1
This name stands for “Load Flow using Gauss-Seidel Method”; it’s written in a TI-89 Titanium. The formulas used in it are based on this book: “Power System Analysis by Hadi Saadat”, The program is not written for just giving the final answer, it solves the problem step by step and is specially useful in tests because most of the time you are supposed to solve the problem only for a few steps and write down the procedure, however you can use it for reaching a final answer just by a few changes but when there are programs like POWERWORLD or DIgSILENT I think it won’t be needed. Only those who have solved load flow problem with at least 3 bus and 4 iterations will understand how much useful this program can be however it is still very helpful for smaller networks. There is also a subprogram which calculates the Ybus matrix. The Ybus calculated after running this program can be used in other programs that I have written like Lfnewton or Lffdcpld. By inversing this matrix you calculate Zbus which is helpful especially when you are going to solve a short circuit problem. Required slack bus power, transferred power between buses, power loss on lines, current flowing through the lines and some other parameters of system are calculated too.
lfnewton.zip194k08-02-12File is not ratedLFNewton1.0

As we will see through an example, learning how the program works is pretty easy. The same as LFGausse the formulas used in it are based on “Power System Analysis by Hadi Saadat”

psa.pwanlzr.zip17k14-01-24File is not ratedpwanlzr 2.5
The main things this program is for: 1-Calculating current of load 2-Power factor correction (using a capacitor) Most of the time in a power system problem, the load is described by its power dissipation, for example we may know |S|, V, and PF or maybe Q, V, and PF, and we want to calculate some other information about the load. This program will ask you for known parameters and then calculates the current of the load plus some other information. While entering data, you don't need to convert line and phase parameter to each other (the program will do this for you). After calculating load parameters, you will have the option to enter a desired power factor, then the capacitor to reach that PF will be calculated. Some of the calculated parameters are stored in one-letter variables for ease of access in the future, these include: Z = phase impedance of load X = phase reactance of the capacitor • V = phase voltage • S = single phase power Q = single phase reactive power • P = single phase active power • I = phase current • F = frequency. Note that: There is always a 30 degree difference between phase and line voltages/currents. Answers are calculated accordingly.

rlocdata.zip123k09-04-05File is not ratedRoot Locus Data
(Originally submitted 2005-10-14) Root Locus Data calculator. Calculates three most quintessential features pertaining to a root locus; namely its (1) Behavior at infinity, (2) Real-axis breakaway and break in points, and (3) Angles of arrival and departure. Any combination of positive/negative feedback and gain are supported. Handles non-minimum as well as minimum phase systems. Multiplicity of the zeros and poles are also taken care of in the program.

Speaker enclosure calculation and design program. Offers sealed and vented boxes, crossovers, impedance compensation and attenuation networks, series notch filters, and the choice to optimize calculations based on Bullock's formulas. Easy-to-use interface and swift navigation. Still under development but constantly evolving. I've been writing this program for over a week now from a halfway house downtown.. finishing up a 4-year prison sentence.... enjoy :)
