Digital computer information control applications are constantly being created for different electrical power systems. Well-designed programmers, complex power systems can be converted to simpler and adequate systems. The transient analysis of software programs combined with the enhanced operational parameter transformation is the basis of the primary structure’s calculations acceleration. The possibility of fundamental simulations was explored both in the modelling of the load flow control of complex electrical power systems and in the identification of electromagnetic short circuit transients. It is no wonder that many programs have appeared recently, including those that analyze the load flow by performing electric voltage calculations with extremely accurate results. In addition, the equipment is evaluated automatically, and computational summaries are created with the addition of warnings. Analyzing electrical load flow and smart graphics play a big role in the efficiency of programs and increase their use of people. It is worth talking about the efficiency of the programs for calculating the electrical load that has gained popularity in recent times. Considering that one of the programs is DlgSilent, which will be our focus in this project because it is the program used. As for the other systems, find ASPEN, ETAP, PSLF, RADIRING, and the famous program MATLAB.
DIgSILENT Power Factory:
Comparison between systems shows the importance and difference of each program. Several calculating methods for the load flow, including the complete AC Newton-Raphson (balanced and unequalled) method and linear DC methods are included in DIgSILENT Power Factory. The improved Newton Raphson non-decoupled solution technology with current and/or power malfunction iterations generates round-off error for all busses below 1kVA. The algorithms implemented are extremely stable and convergent. Various iteration levels guarantee convergence under all conditions, with automatic optional relaxation and constraint change The DC charging stream is amazingly quick and vigorous for dynamic force streams and voltage points (direct framework; no cycles required). Knowing the balanced and unequalled load flow for AC and DC networks, DlgSILENT estimates. Moreover, the DC load flow is analyzed. The feature of this software is that it offers a rapid and efficient convergence of altered starting points with the latest numerical solutions for active/reactive voltage and power control functions, such as SVC and user switching controllers.[1]
