Local Coordinative Reactive Power Control Method to Manage Voltage/Momentary Reactive Reserve

전압 및 순동무효예비력 확보를 위한 지역 변전소에서의 무효전력제어장치 협조방식 연구

This paper discusses local reactive power control method of substation which has FACTS controller(STATCOM) and other reactive power controllers. Not only The relation between entral control and local control method was discussed, but also local STATCOM control methd was done. With this results, revised coordinative control method which can implement system voltage sensitivity characteristics of each control devices. Also, this method can give proper solution for system status which requires momentary reactive reserve. This method is expected to be applied to control multiple substation reactive power devices which is combined with SCADA system.
