Virtual instrument measures harmonic filter duty
- Georgia Power Co., Atlanta, GA (United States). Protection and Control Dept.
Harmonic filters for a static var compensator (SVC) suppress power frequency harmonics generated by the nonlinear characteristic of the thyristor controlled reactors and electric arc furnace loads. SVC filters also provide the 60 Hz capacitive current needed by the SVC to reduce bus voltage flicker. The harmonic filter for a static var compensator is often the weak link in the electric arc furnace service reliability. During the period 1990 to 1994, the SVC filters for steel mill furnaces experienced four reactor failures and eleven capacitor can failures. The first step toward improving SVC filter reliability was measuring the stress to the filter components. This article describes the use of virtual instruments in this analysis.
