  Line reactor

  A line reactor is needed for high short-circuit power levels, partly to protect the actual inverter against excessive harmonic currents, and thus against overload, and partly to limit line harmonics to the permitted values. The harmonic currents are limited by the total inductance comprising the line reactor and mains supply cable inductance. Line reactors can be omitted if the mains supply cable inductance is increased sufficiently, i.e., the value of R_SC must be sufficiently small.

  R_SC = Relative Short-Circuit power: Ratio of short-circuit power S_{k Line} at the supply connection point to the fundamental apparent power S_inv of the connected inverters (to IEC 60146‑1‑1).

  

  PM330 Power Module requirements:

  Power	Line reactor can be omitted	Line reactor required
  kW (hp)	for RSC	for RSC
  < 200 (268)	≤ 43	> 43
  200 (268) ... 500 (671)	≤ 33	> 33
  > 500 (671)	≤ 20	> 20

  
  
  

  It is recommended that a line reactor is always connected on the line side of the inverter, as in practice, it is often not known on which supply configuration individual inverters are to be operated, i.e. which supply short-circuit power is present at the inverter connection point.

  A line reactor can only be dispensed with when the value for R_SC is less than that in the above table. This is the case, when the inverter, as shown in the following figure, is connected to the line through a transformer with the appropriate rating.

  Notice:

  A line reactor is always needed if a line filter is used.

  

  In this case, the line short-circuit power S_k1 at the connection point of the inverter is approximately:

  S_k1 = S_transf/(u_{k transf} + S_transf / S_{k2 line})

  S_transf = Transformer rated power

  S_{K2 line} = Short-circuit power of the higher-level voltage level

  u_{k transf} = Relative short-circuit voltage
