Damping of Subsynchronous Resonance Using a Vsc-hvdc Link
نویسندگان
چکیده
A possible detrimental effect of onshore series compensation in the GB grid is the appearance of subsynchronous resonance (SSR). In this paper, a control scheme for a VSC-HVDC link capable of damping subsynchronous oscillations is proposed in order to effectively counteract the potential damage caused by SSR in steam turbines. The VSC-HVDC link has been modelled to maintain its primary functions of bulk power transmission and reactive power compensation and additional positive damping upon SSR occurrence.

Abstract: This paper presents a robust non-linear hybrid controller based on Type-2 fuzzy and sliding mode control strategy for VSC-HVDC transmission link, which inherits the benefits of these two methods. The interval Type-2 fuzzy (IT2FSMC) is used to handle the uncertainties to enhance the real time performance. The sliding mode control combines with the fuzzy system to compensate the influen...
