Abstract

With the continuous development of power electronics technology, static synchronous compensator (STATCOM) structure increasingly multiplex. When the load current check point and the compensation injection point of STATCOM in different position and exist the difference of the phase and amplitude, which can produce a difference of detection.To solve this problem, this paper proposes an improved STATCOM compensation instruction current detection method based on ip-iq algorithm. This method can eliminate the error and improve the detection accuracy by setting the preset phase angle and proportional integral (PI) controller according to the difference of voltage phase and amplitude between the check point and the compensation point, thus breaking the limitation that traditional ip-iq algorithm is only applicable in the case of that the detecting point and the compensation point in the same position, which improve the accuracy of detection. Theoretical analysis and simulation results show the effectiveness of the proposed method in this paper.
