Application of Static Reactive Power Compensation Device in Power System Stability

Abstract:

With the rapid economic development in Liaoning Province, very rapid growth in electricity load, especially steel and fused magnesium commercial power. After the implementation of TOU price, Liaoning power grid voltage fluctuation is increased by that some enterprises were concentrated in low hours of electricity. Some power users were affected by lacking the means of dynamic reactive power. To point the necessity of application of the SVC, the existing of 66kV and 220kV grid power quality status are analyzed and simulated. The SVC compensation capacity and filter parameters are systematically design, after the transformation of the system and the simulation proved that the grid can achieve the design requirements.
