摘要：

With the proliferation of harmonic-producing loads, the possibility of system-capacitor resonance has become a routine concern for shunt capacitor applications. Using a real-life case, this paper presents a practical procedure for assessing the likelihood and consequences of system-capacitor resonance. The results show that it is not always necessary to mitigate harmonic resonance even if a capacitor resonates with the system at key harmonic frequencies. This paper proposes the use of capacitor loading conditions as a method to evaluate the severity of harmonic resonance. The capacitor operating voltage is found to have a significant impact on the outcome of the resonance. (C) 2001 Elsevier Science B.V. All rights reserved.
