Static Synchronous Series Compensator: A Solid-State Approach to the Series Compensation of Transmission Lines

Transient Stability Enhancement in Power System Using DSSC and DSSC with FLC

“…As a result, the transmitted power becomes a parametric function of the injected voltage and can be stated as the sequel: Where : V1 and V2 = the bus voltage magnitudes; Vq = the series injected voltage magnitude; = the voltage phase difference; and XL = the impedance of the line, assumed to be purely inductive. The DSSC can simply increase the transmittable power as well as decrease it by reversing the polarity of the injected ac voltage [15]. This is worth noting that this feature is responsible for corroborating the DSSC salient ability for power flow control in the overall system.…”

“…Fuzzy logic comprises fuzzy sets, which is a way of representing non-statistical uncertainty and approximate reasoning, including the operations used to make inferences in fuzzy logic [13], [14]. In recent years, Fuzzy logic control (FLC) with its capabilities, has been applied to the supplementary control design of FACTS devices for transient stability enhancement of a power system [15].…”

Tuning of PI and PID Controller with STATCOM, SSSC and UPFC for Minimizing Damping of Oscillation

“…The Static Synchronous Series Compensator (SSSC) comprises of a voltage source converter in series with coupling transformer in the line. SSSC can inject a voltage with controllable magnitude and phase angle at the line frequency and found to be more capable of handling power flow control, improvements of transient stability and damping of oscillations [17,18,19].…”

SSR mitigation with SSSC thanks to fuzzy control

“…The static synchronous series compensator (SSSC) is one of the FACTS devices utilized by a gate turn-off thyristor-based voltage source inverter yielding controllable compensating voltage over an identical capacitive and inductive range that is independent of the magnitude of the line current [13,14].…”
