### In this post, the free download link of PSS/E 33 software is placed for free so that students and professors can use and download it for free.\r\n### \r\nTo buy PSS/E 34 and PSS/E 35 software, contact PSS/E 36 at 09126717215.\r\nIn this post, we intend to introduce and download the Siemens PSSE software from Siemens. Since its inception in 1976, this software has entered the field of power system simulation. PSSE software was designed in PTI company of America and is currently used in more than 50 countries. Powerful and complex computing algorithms in this software have turned it into a reliable tool for modeling, analyzing and planning extensive power systems.\r\nPSS/E or PSSE software can be used in various cases such as simulation, analysis and optimization of power system performance. Other features of this software include the possibility of using it on different operating systems such as Windows XP, 7 and 10, Sun Solaris, 2.X, HP 9000 HP-UX 10 DEC ALPHA DIGITAL UNIX, IBM AIX DEC ALPHA OPEN VMS He remembered\r\n\r\n** Calculation of load distribution\r\nCalculation of optimal load distribution (OPF)\r\nAnalysis of symmetrical and asymmetrical short circuit\r\nSimulation of power system dynamics (both short-term and long-term modes)\r\nOptimization to reduce network volume\r\nModal signal analysis\r\nCalculate the cost amount\r\nAnalysis and analysis of power transmission\r\nDisplay of three-phase and phase-to-earth faults on the single-line diagram of power transmission\r\nSimultaneous occurrence of complex events in several buses and different points of the transmission system\r\nDisplay all voltages and currents\r\nIndependent switching of poles\r\nCircuit breaker calculations\r\nThe possibility of stopping and restarting the simulation at any desired time\r\nIt is possible to check the effects of any type of disturbance, such as the occurrence of an error, generator cut-off, engine start-up and load removal\r\nAbility to calculate response ratio and open circuit transient response in excitation systems\r\nThe possibility of estimating the parameters of synchronous and induction machines**\r\n\r\n\r\n### PSS/E software has the following models for its simulations:\r\n\r\n1. Various and precise models of generator, excitation system, governor and stabilizer\r\n2. Complex load models, static reactive power and multi-terminal HVDC models\r\n3. Distance, underfrequency and high current relay models\r\n4. The possibility of checking the effect of frequency on network models and parameters\r\n5. The possibility of defining the model by the user for any type of control process (without increasing the program execution time)\r\n\r\n**Using optimal load balancing**, system performance cost can be reduced. The OPF can solve the full load spreading equation by maintaining the real and virtual power coupling to obtain the amount of each of them. OPF can also be used to quickly define and solve the most complex power system optimization problems. In PSS/E software, it is possible to check very scattered systems or very dense systems (with 500,000 buses). Another important advantage of OPF is in choosing the best solution for the problem. In the conventional load spreading methods, the engineer has to check different solutions to achieve the right solution, while the OPF tool directly
