Abstract: Aiming at the exceeding limit of shortcircuit current in connecting to power system of the small power plants, the advantages and disadvantages of various suppression measures of shortcircuit current were compared and analyzed by the calculations and verifications of a practical project. The influence of installation position of the currentlimiting reactor on current suppression effect was illustrated emphatically, and some related suggestions were proposed for engineering design as reference.

Key words: small power plant, connecting to power system, short-circuit current, current-limiting reactor, power system analysis software package (PSASP)
