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 1 MW.

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 Star. You can go there by clicking this link, http://philippineenergynews.blogspot.com. Read the rest of this entry »

Last week, one of our clients sent us some questions 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.
Does this mean that the DSL Segregation Software is inaccurate on its computation? Read the rest of this entry »

I’m wondering whether a capacitor compensation is an advisable option to improve the voltage security of a transmission system with continous power demand and supply fluctuations, 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).
