“…In order to mitigate and suppress SSR, several control schemes have been proposed in [4][5][6][7] and [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Generally speaking, the above control schemes can be categorized into two classes.…”

“…Given that the most severe victims of SSR are the generators, another class of the damping controls called as generator-side suppression schemes were proposed in [16][17][18][19][20][21][22][23][24][25][26][27][28], whose control effects are more direct for the generator shafts. The negative filters placed at the generator terminal for SSR damping were presented in [16][17][18].…”

“…To achieve the direct and independent control effects, plenty of dedicated SSR damping controllers placed at generator side are reported in [4,[24][25][26][27][28]. The static var compensator based sub-synchronous damping control (SVC-SSDC) was designed and put into practice in [4,24], which contributes to the three-mode SSR mitigation in the early Jinjie Power Plant.…”

Multimodal sub-synchronous resonance (SSR) induced by the interactions between the generator shafts and the fixed series capacitors has become a serious threat for the power system. To overcome this, a voltage source converter (VSC) based controller for multimodal SSR suppression, named sub-synchronous resonance dynamic suppressor (SSRDS), is presented and analyzed in this paper. The controller is placed at the point of common coupling (PCC) of the power plant for multi-generator SSR suppression purpose so that the investment costs can be minimized while making sure the requirements of the SSR damping. To quantify the contribution of SSRDS to the SSR damping, the damping torque analysis is carried out, which can reveal the influences of the operating conditions and the correlated control parameters on the damping performance. Furthermore, to avoid the negative affects between the different TMs in close range as well as maximize the damping ability of SSRDS, the parameters tuning method of the mode filters and the gain and phase shifters are proposed. A detailed nonlinear simulation model is established in PSCAD/EMTDC based on the Jinjie series compensated transmission system located in China. The damping torque analysis, the eigenvalues analysis and the simulation results have fully demonstrated the effectiveness and the robustness of the proposed SSRDS for multi-generator and multimodal SSR suppression under both small and large disturbances in various operating conditions.

“…However, existing PMUs cannot efficiently monitor the wide range of SSR frequencies [5]. To avoid the use of communications, local measurements may be employed to estimate subsynchronous frequency (SSF) components [17], [19], [22]. Potential alternatives include the use of low-pass filter and recursive least square based estimation and damping methods [19], [21]; Kalman filters [17]; and multi-modal damping [22].…”

Infrastructure reinforcement using high-voltage direct-current (HVDC) links and series compensation has been proposed to boost the power transmission capacity of existing ac grids. However, deployment of series capacitors may lead to subsynchronous resonance (SSR). Besides providing bulk power transfer, voltage source converter (VSC) based HVDC links can be effectively used to damp SSR. To this end, this paper presents a method for the real-time estimation of the subsynchronous frequency component present in series-compensated transmission lines-key information required for the optimal design of damping controllers. A state-space representation has been formulated and an eigenvalue analysis has been performed to evaluate the impact of a VSC-HVDC link on the torsional modes of nearby connected thermal generation plants. Furthermore, the seriescompensated system has been implemented in a real-time digital simulator and connected to a VSC-HVDC scaled-down test-rig to perform hardware-in-the-loop tests. The efficacy and operational performance of the ac/dc network while providing SSR damping is tested through a series of experiments. The proposed estimation and damping method shows a good performance both in timedomain simulations and laboratory experiments.
