Hybrid Series Capacitive Compensation Scheme In Damping Power System Oscillations Using Tcsc
نویسنده
چکیده
This paper demonstrates the phase imbalanced series capacitive compensation concept to enhance power system dynamics as it has the potential of damping power swing as well as sub synchronous resonance oscillations. A scheme for a phase imbalanced capacitive compensation is shown. It is a “hybrid” series compensation scheme, where the series capacitive compensation in one phase is created using a single-phase TCSC in series with a fixed capacitor (Cc), and the other two phases are compensated by fixed series capacitors (C).

Application of an Additive Self-tuning Controller for Static Synchronous Series Compensator for Damping of Sub-synchronous Resonance Oscillations
In this paper, an additive self-tuning (ST) control scheme is presented for a static synchronous series compensator (SSSC) to improve performance of conventional PI control system for damping sub-synchronous resonance (SSR) oscillations. The active and reactve series compensation are provided by a three-level 24-pulse SSSC and fixed capacitor. The proposed ST controller consists of a pole shift...

متن کاملA new control strategy for SSSC to improve low-frequency oscillations damping
When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...
