The Configuration Scheme of Reactive Power Compensation Capacity on the 110kv Substation

Abstract

When the main transformers need to be uprated on the 110kV substation of Mian Cheng, we need to analyze the long-term flow calculation and determine reactive power compensation capacity. On the basis of the current program on the 110kV substation to determine, we proposed two configurations about reactive power compensation capacity for the long term program. The voltage fluctuation and reactive power compensation capacity are analyzed by theoretical analysis and simulation for verification. And combining with the requirements of the relevant regulations, the optimal reactive power compensation scheme is selected reasonably.
