Wind generator: its influence on power grid transient stability

October 31st, 2018 | Make a comment | Posted in Power quality

Hi I’m Mile and I would like to tell you about wind generator today…In the last years, usage of wind power has grown greatly throughout the whole world.

Together with the development and the improved production technology, the wind turbine performance has drastically improved.

Considering the fact that wind plants grow in size and number in power networks worldwide, many questions about the possible impacts on the electrical grid arise, and there is need of answers to those questions and solutions to the potential problems.

Harmonics effect in the power network: define & compensate them

October 9th, 2018 | Make a comment | Posted in Power quality

megaphone-redWhat’s the definition of harmonics? Why are they bad for the electrical equipment? How to define harmonics effect? How to compensate?

Read the following article by one of your fellow electrical engineer who sent us good information about this topic a couple of weeks ago.

My name is Mile and here’s my article about my work on the following huge electrical engineering project. Enjoy :)

The production capacity of REK Bitola, the biggest power plant in Republic of Macedonia, is around 80% of all the consumed electric power in Macedonia. Regarding that fact, the Suvodol and Brod Gneotino mines, are the vital points from where the plant receives coal, in table 1 I have presented the measured installed power of the both mines and their power blocks.

Current protection

Current protection schemes are integrated into power system designs to protect the power system components from the excessive withdrawal of current and short-circuit currents. Excessive overcurrents could occur on many different power system components such as motors causing hazards if not cleared within the safe time frame.
