IEEE offers lots of good papers and references for your projects and research, however, IEEE publications are downloadable exclusively for its members only. Sometimes, access also depends on the level of membership in the organizations. Membership fees range from USD 131 to USD 165. It’s not that high though, but if you will only need one to two papers for your project, I think it’s not worth the cost. Read the entire entry …
Unlike DC generator, synchronous generator, which is the commonly used type of generator for power plants around the world, need to have the same frequency and in-phase to the grid frequency before connecting. This is also the reason why the act of interconnecting a synchronous generator to the Transmission Grid is synchronization.

The algorithm for the backward-forward sweep power flow simulation for three-phase unbalance radial distribution system was formulated by D. Shirmohammadi and C. S. Cheng on their paper for the IEEE Transactions on Power Systems. The algorithm is quite simple since it was only based from the two basic laws in electrical engineering, the kirchhoff’ s current and voltage laws. Read the entire entry …
Borland C++ Builder (BCB) is a good tool for all range (both object-oriented and/or dynamic) of applications that require a utilization of a graphical user interface (GUI). Traditional C/C++ programs can also be easily integrated with the drag-and-drop tool used for creating a graphical user interface.

The Siemens - PTI PSSE power flow simulator is a well known and reliable power flow simulation tool for simulating power systems of up to large scale in size. However, just like other sophisticated analysis tools, it’s hard to learn the basics of using it, specially, for the new user of the software.

DC to AC inverter’s function is to convert Direct Current (DC) voltage to Alternating Current (AC) voltage. DC to AC inverter is commonly used for converting High Voltage DC (HVDC) transmission voltage back to AC, and for converting the DC output voltage of a photovoltaic (PV) solar panel to suitable AC voltage.

Given a set of data points (say, X and Y), cftool toolbox of MATLAB can derive an equation that can best fit on the set of points. Type of fit can either be polynomial up to 9th degree, Fourier, exponential, and more. Read the entire entry …
Currently, the transmission of electrical energy from bulk power generators all the way to household, commercial and industrial consumers is made mostly through high voltage alternating current (AC) transmission and distribution systems, and through a series of voltage transformations to reduce losses and minimize cost. Voltage levels used are of standard values.
