bda.zip48k12-06-17File is not ratedBlock Diagram Model Simulator
Block diagram algebra simulator for TI89, TI92P and Voyage. Simulates continuous and discrete dynamical systems described by a block diagram algebra model like Simulink. Unlike the Simulink do it symbolically and return the resulting response of the system as an algebraic expression instead of a numerically calculated response. That’s useful when you are about to manipulate with the system response through equations further. Particularly exams and tests where there is necessary to write the results down on paper as an expression and where you are barely supposed to have an instrument do it for you so you every time leave an impression of doing it by your head and hand. Draw a chart of the response interpreted as an expression is a fundamental feature of these calculators.

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
“Load Flow using Newton Rophson Method” The program leads you to final answer step by step & everything is shown on the screen.

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”

lsa122ams208.zip45k03-05-20File is not ratedLSA 2000 version 1.2.2 for AMS 2.08 (or greater)
Laser Safety Advisor (LSA) 2000 performs a laser hazard analysis using methods that comply with ANSI Z136.1-2000. This program more closely reproduces the numeric results that would be generated by a manual laser hazard analysis, using exactly the methods that are specified in the ANSI standard. This updated version of the package contains improvements to the analytic engine. The program is now much faster than the original release, because the current version bypasses the .nSolve. function when it generates numeric solutions for implicit equations. This version is also better at screening out nonsensical input combinations.
