This paper presents the DQ transfomation and space vector modulation method to develop a control algorithm of distribution STATCON(STATic CONdenser) for line voltage regulation, dc link voltage regulation and harmonics compensation. The Performance analysis of a PI with ramp comparision and synchronous reference frame current controller is carried out. Based on these analysis, the control performances are desirable to compensate the harmonics and to regulate de link and line voltage of Distribution line.

About supply and demand to see that you need to match, the limitations of wind power capacity is low demand and the commitment of the general generator will exist between the minimum generation. if the turbine's output can be controlled, The limitation of wind power capacity will be adopted based on instant power generation. Namely, The minimum limits of wind power generation based load operation by calculating the amount that is higher than if the output should be restricted to highest operation. in this paper, we committed to the demand for low enough that the combination of the general generator of wind power capacity to accommodate the operation of determining whether the limit is intended to. For this, power system analysis program PSS/E was used, Jeju system by implementing the model simulations were performed.

본 논문에서는 송전선로에 직렬로 삽입되어 선로의 리액턴스를 동적으로 보상하는 인버터식 직렬보상기에 대한 동적 응동 해석을 기술하고 있다. 이 직렬보상기는 다중펄스로 동작하는 전압원인버터와 결합변압기, 그리고 제어장치로 구성되어 있으며, 점호각을 조절하여 선로의 리액턴스를 가변하고 용량성 뿐만 아니라 유도성 보상도 가능하다. 이 보상기로 선로의 리액턴스를 감소시키면 전송 유효전력의 증각가 가능한데, 이러한 효과를 본 논문에서는 단일기-무한대-버스 전력계통에 대해 EMTP를 이용한 시뮬레션으로 확인하였으며, 또한 축소모형 제작과 실험을 통해 실험적으로 확인하였다.
