Bhaskar Sen's Power System Lab


BSPSLAB ( Bhaskar Sen's Power System Lab ) is a general purpose Power System Simulation and Analysis tool.
The purpose of a power flow simulation analysis program is to compute precise steady-state voltages of all buses in the power system network, and from them the real and reactive power flows into every line and transformer, under the assumption of known generation and load.

This is its basic function; the modeling of controls such as tap-changing transformers, generator reactive power output, area interchange and various control equipment like AVR , SVC ,HVDC etc will be added as project progresses.

The power flow problem requires the solution of a large set of equations that are nonlinear in the variable of interest, voltage. Large nonlinear problems are usually best solved through a process of linearization and iteration. two most effective algorithms for power flow solutions available today: Newton-Raphson and Fast Decoupled method. The project aims to start with Newton-Raphson method and then to add Fast Decoupled method .

The One-Line Diagram Editor will allow the users to quickly enter the data in an intutive way . Netlist method of data entry will also be supported . During setup of the study, user could click on lines to take them out of service or on bus ties to open or close them. You may click on buses to change local generation or load, adjust load and generation in arbitrary bus groups or in predefined bus sets. Click on graphical objects to examine and edit the associated database data. Immediately following a solution, real and reactive flows and bus voltages are displayed on the diagram. OL diagram will show overloaded lines or over/under voltage buses by automatically redrawing them with a particular color.

This project also aims at building a comprehensive library of models encompassing all aspects of AC and DC power systems and controls.
