| Abstract: | It is very difficult to carry on accurate detection to harmonic in the power system because of its randomicity, distribution and non-stability. It has been a constant effort for researchers to explore more effective detecting and realization methods. Therefore new methods emerge as the times require on the expansion and improvement of the conventional method. The paper analysis and review some novel methods appeared in recent harmonic detecting area, and predict the development tendency of harmonic detecting in the electric system. |
