A Frequency Estimation Algorithm using Phase Angle Difference Calculation in Power System

페이저 상차각 연산에 의한 전력계통 주파수 추정 알고리즘

Frequency and phasor are the most important quantities in power system operation because they can reflect the whole power system situation. This paper proposes a design and implementation using phase angle difference calculation for frequency measuring in power system. The process is considered to be complicated as compared to the present proposed method. Performance test results, using signals from Excel program, indicate that the proposed technique can provide accurate estimates within 16ms.
