Instantaneously Active/Reactive Power Compensation of Distribution Static Compensator using Phase Shift

배전용 정지형 보상기의 위상변이를 이용한 순시 유효/무효전력 보상

DSTATCOM(Distribution STATic COMpensator) is one of the custom power devices, and protects a distribution line from unbalanced and harmonic current caused by non-linear and unbalanced loads. Conventional researches use a LPF(Low Pass Filter) to eliminate ripple component at the calculation of compensation current. This paper proposes a calculation of compensation current using phase shift that can be a counterproposal of conventional methods using LPF.
