“…HVDC converter control system may cause SSO in together with the torsional vibration negative feedback of large unit shaft nearby. This problem is initially identified in the Square Butte DC power transmission project [1], and the CU and IPP projects in the United States and some of other HVDC power transmission projects all show the occurrence possibility of SSO.…”

“…The undesirable interactions between the HVDC terminal and the 11.5 Hz torsional mode of an electrically-close turbinegenerator unit were noted during the field tests conducted at Square Butte in North Dakota [8]. Subsequently, it was revealed that the HVDC rectifier stations with constant current control may introduce negative damping on the nearby generating units [8].…”

“…Subsequently, it was revealed that the HVDC rectifier stations with constant current control may introduce negative damping on the nearby generating units [8]. A current-controlled voltage-source converter, located electrically close to the generator may also introduce negative damping in the certain frequency range and proper design of current controller may nullify the possibility of negative damping [9].…”

Negnevitsky, "Subsynchronous torsional interaction behaviour of wind turbine-generator unit connected to an HVDC system," in IECON 2010: 36th Abstract-Utilisation of wind energy to generate electricity has attracted considerable attention worldwide, and is rapidlygrowing. The integration of large wind farms with high voltage direct current (HVDC) transmission network could be one of the preferred options for supplying bulk power over a long distance. Since HVDC rectifier stations with constant current control may introduce negative damping on the nearby generating units, it is important to identify the torsional interaction characteristics between turbine-generator units and the HVDC systems over a frequency range of interest. However, very little related information exists in regard to wind turbine-generators. This paper presents the electromagnetic transient time domain analysis to investigate the possible subsynchronous torsional interaction (SSTI) phenomenon of fixed-speed (induction machine based) wind turbine-generator (WTG) unit interconnected to a CIGRE first HVDC benchmark system. Electrical disturbances, such as three-phase short circuit fault at the inverter station and DC power flow change are simulated to examine the possible dynamic interactions of the WTG unit. Simulation studies are conducted using PSCAD R /EMTDC c .

“…In 1977, the Square Butter HVDC system in USA suffered from the subsynchronous oscillation (SSO) [1]. Postmortem studies revealed that this dynamic instable phenomenon occurred at the side of the HVDC rectifier, and was mostly attributed to the negative damping torque caused by the inappropriate control of the HVDC link [1,2].…”

Since then, many analog simulators and computerbased simulation programs have been developed to study the SSO caused by HVDC links [3][4][5][6].…”

SUMMARYIt is well documented that an inappropriate HVDC controller will cause dynamic instability in an AC/DC system. In order to have a better analysis on the mechanism of this phenomenon, this paper proposes a generic theoretical equation of electric damping coefficient of a HVDC link using the complex torque coefficient (CTC) method for quantitatively analysis of the damping characteristics of different types of HVDC control systems. Furthermore, a theoretical design methodology will also be established to improve the performances of the HVDC primary and auxiliary control systems with an application example.
