Non-Full Phase Resonance Overvoltage for 500 kV Transmission Line with Shunt Reactors

Based on the principle of the resonance of the non-full phase and the adjacent line,this paper analyzes the resonance inhibiting mathematical model of the small reactor of the neutral point of the HV reactor and calculates the numerical solution of the small reactor corresponding to the typical line in order to avoid the resonance.Through theoretical analysis and ATP simulation of the actual line,several influen-cing factors of the non-phase are studied with corresponding measures for resonance suppression presented.
