When the load current check point and compensation injection point of the Static Synchronous Compensator (STATCOM) are at different positions and there are differences in phase and amplitude, there will be a detection difference. To solve this problem, this paper proposes an improved STATCOM compensation command current detection method based on the ip-iq algorithm. This method can eliminate errors and improve detection accuracy by setting the preset phase angle and proportional integral (PI) controller according to the voltage phase and amplitude difference between the check point and the compensation point, thus breaking through the traditional ip-iq. The algorithm is only applicable to the situation where the detection point and the compensation point are at the same position, which improves the accuracy of detection. Theoretical analysis and simulation results show the effectiveness of the method. S
