Amidst the rising cost of fuel in the world market and the implementation of EVAT that resulted to a tremendous increase of oil products such as gasoline, (http://philippineenergynews.blogspot.com/2006/05/oil-prices-up-by-p050.html), Energy Companies still have the opportunity to gain profit that is even more higher than the previous quarter of the year and getting higher and higher every year, while in contrast, the oil prices is also getting higher almost every less than a month.

Last February and, just recently, this month of May, I had a one-on-one discussion with fellow local engineers who happen to have a wide range of experience in developing and implementing modern day, as well as, old technology to meet the human needs and for profit, as well. And like me, we always like to […]

Last January 2006, we were invited to attended a conference/seminar about mini-hydropower experiences and its development in the Philippines. Speakers discussed lots of things and issues about this kind of power generation, including the requirements and time line for a green field project development.

Many thought that it is a loss for MERALCO if it gave-up its large consumers with a power consumption of 1 MW or more (and allow them to have a freedom to choose its own power supplier) since a big chunk of its consumers are industrial and commercial users which utilize power of more that […]

Well, since one of our interests is the field of electrical engineering, including electric power industry and energy, I’m so lucky to find a blog that post some of the energy related news in the Philippines. Most of them seems like captured in the internet from 3 big news source, Inquirer, Manila Bulletin and Philippine […]

Below are the links of the two types of IEEE test systems for power system analysis.

Last week, one of our clients sent us some question about the output of our Distribution System Loss Segregator (A.K.A DSL Segregator), which currently, on the second stage of its development.
Here is one of their observation;
One of their feeders has around 1,800 KVAR of shunt capacitors installed in three parts of the primary distribution line. Initially, base on the output of the Segregator, energy losses at the primary line is around 460 Kwh. However, when they removed the capacitors, they noticed that the energy loss decreases to 390 Kwh. This is disturbing because the effect of that change is opposite to what should be expected, that is, increase the losses because the capacitor that was removed was intended to supply Kvar that helps in decreasing losses in the line. Thereby, according to them, removing capacitor compensation should go back into a higher loss system.

I’m wondering whether capacitor compensation will improve the voltage security of a transmission system, especially for a radial system, with both dispersed synchronous generators and wind power plants. […]

Last week, I attended a training seminar on PV solar system organized by the Japan International Cooperation Agency (JIAC) and the Philippine Department of Energy (DOE). Although, PV solar system is capable of supplying large amount of power, like the 1 MW solar plant at Cagayan de Oro and owned by CEPALCO, the training focused only of Solar Home System (SHS) and Battery Charging System (BCS).

Just recently found another good website and reference for Power Systems Engineers that specializes on Electric Power systems simulations, control, reliability, market, and other related fields.

I was confused with Hadi Saadat’s discussion of power flow analysis on his book, Power System Analysis.
