COORDINATION CONTROL METHOD FOR FACTS DEVICES OF NEW ENERGY DELIVERY SYSTEM

摘要

The present invention provides a coordination control method for FACTS devices of a new energy delivery system. The method comprises inner layer control, outer layer control and outermost layer control, priority level of the outermost layer control is higher than that of the outer layer control, and priority level of the outer layer control is higher than that of the inner layer control. The inner layer control can ensure that voltage of a transformer substation can be accurately controlled in a certain value or a certain range, and when the system is in large disturbance, the outer layer control and the outermost layer control can provide urgent reactive power support, so that the voltage of the transformer substation can rapidly recover to an allowed range. Three layers of voltage control are combined so that motions of a plurality of FACTS devices can be coordinated and controlled in a centralized, high accuracy and high efficiency mode, and the engineering adaptability is high.
