Abstract: Analysis was made to the feasibility of the harmonic suppression and reactive power compensation scheme in the distribution network of Xi’an residential quarter. Introduction was made to the basic principle of the harmonic suppression and reactive power compensation. Aiming at the actuality of quality of power supply in residential area, this paper established the target function with the minimum network loss, taking into account the voltage stability and equipment cost at the same time. The scheme effectively reduced active network loss of the system and improved the voltage stability. This method provided certain reference values for the harmonic suppression of large-scaled distribution network.
Key words: residential area; active power loss; harmonic suppression; reactive power compensation
