Abstract :
The paper discusses the operation and control characteristics of a Distribution Static Compensator (DSTATCOM). The main aim of the DSTATCOM is to protect the utility system from the ill effects of customer loads. The DSTATCOM, when operated in current control mode, cancels the distortion caused by the load, such that current drawn by the compensated load is a pure balanced sinusoid. In this paper it is assumed that the load draws noninteger harmonic current such that its waveform is aperiodic in nature. An algorithm is proposed for extracting phasor symmetrical components from the samples of these waveforms. The proposed algorithm is verified through extensive digital computer simulation studies using MATLAB.
