Solutions for Governance and Suppression of Power Harmonic in Cities

Based on the current status of cities’ power supply and distribution system, this paper conducts theoretical and experimental investigations over the generation, harzards as well as the restraining and suppression techniques of power harmonics. A solution of scheme selection for controlling and suppressing power harmonics suitable for the current power supply and distribution system of big and medium-sized cities is proposed. This study not only provides important implications for big and medium-sized cities, but also provides substantial reference value for cont rolling and suppressing power harmonics in the public utility system in China.
