【Abstract】 The significance and method of the harmonic control of the air cooling island fan cooling system are discussed,inverter harmonic management methods are researched, and the main working principle of active power filter is introduced systematically. Aimed at the air cooling island fan cooling system of Shanxi Fugu power plant, management solutions of installing filter compensation devices have been put forward, which include active filter and hybrid active power filter devices,etc. By means of models building and Matlab simulation analysis, simulation results show that the proposed harmonic control schemes have good effects of harmonic elimination and filtering.更多还原
