Sizing filter reactors for industrial electrical grids

Most modern industrial electrical grids are characterized by a significant content of nonlinear loads, creating many operation problems. Power harmonic filters are one of the most effective ways of reducing voltage distortion in electrical grids. The use of power filters solves two main concerns - to reduce the input current harmonic distortion of the power supply system and compensate for the reactive power of loads. As a rule, the sizing nominal parameters of filter circuits is carried out by the power supply system characteristics in stationary (steady) operating condition.
