Abstract：
 The present invention discloses parameter regulating method of non-linear electricity system stabilizer based on frequency domain test and pertains to the technical field of stability control of electric power system. The present invention is characterized in that: test the non-frequency-compensation linear property curves and test the phase angle under different frequency points in the low frequency vibrating range of 0.2 to 2.0Hz from the output point of the stabilizer to the voltage of the generator after the working condition of tested machine unit is fixed; then calculate the lead and lag angle a 1 of the linear part of the output signals of the stabilizer under different frequencies, added with phase angle that has corresponding frequency property, and then decide whether surpass the lead and lag range relative with Delta Omega axle prescribed by national standard; if not surpass, the feedback factor k1, k2 and k3 of the linear part can be calculated out; then the damping coefficient C1 and the gain coefficient C2 can be decided with critical amplification times method and load phase step method. The present invention is easy to be comprehended by commissioning operators and is easy to be populated.
