The way of taking one nth out of capacitor ' s the first harmonic capacitive reactance as its nth harmonic impedance is verified whit the data from tang7c. according to the approximately estimating method, the first harmonic impedance of 220kv system is calculated. on the basis of the models, this paper gives the harmonic equivalent circuit of substation and gives the b ( n ) function of the harmonic time n. when the capacitors has different combination, b ( n ) ' s value will also change, with the inputting local measurement data, the paper studies the series and parallel resonance at the substation, and deduces that the reason the capacitor ' s fuse of tang6c is frequently interrupted is that its capacitor current contains a large number of 5th harmonics, and that the reason the discharging pt of tang7c capacitor being exploded is also that the 7th and 9th harmonic currents are amplified
