Power Quality
Power Quality refers to how reliable and stable the electricity produced by wind turbines is before it goes into the power grid. It's like quality control for electricity. Just as a factory checks its products before shipping, wind farms need to ensure their electricity meets certain standards. This involves monitoring things like voltage consistency and managing any disruptions that might occur when wind speeds change. When you see this term in resumes, it usually means the person has experience making sure wind turbines produce electricity that's safe and usable for homes and businesses.
