Abstract
The purpose of the reactive power control of HVDC system is to balance the reactive power exchanged between the AC and DC systems, and also to mitigate the harms of the harmonics produced by the converters to the system and the primary equipments. The reactive power control is realized mainly by switching of AC filter sub-banks on and off in stepped manner. Different aspects have to be considered for the reactive power control including the quantity of the reactive power being exchanged, limitation of steady state AC voltage, demands and optimizing of harmonic filtering, switching equalization of the sub-banks, elimination of disturbance caused by the sub-bank switching etc. The HVDC reactive power control is of complicated multi-target and multi-boundary control function. Based on the requirement in real HVDC project, the design principle for detailed functions and strategies of reactive power control are analyzed and introduced in this paper.关键词
