Fault current limiting and power system stabilization by static synchronous series compensator

Semiconductor Devices in Solid-State/Hybrid Circuit Breakers: Current Status and Future Trends

“…Further investigation could be on implementation and higher-temperature superconductors; (d) As current-limiting is becoming more intelligent, semiconductor devices will be widely applied, but their reliability must be taken into account; (e) Resistive CL-CB has really high power dissipation, it might be only used for short-term limiting; (f) Inductive CL-CB and L-C based CL-CB are sensitive to frequency changes, so the robustness is not perfect. The dynamic response must be analyzed before any conduction; Static synchronous series compensators (SSSC), as a series-connected semiconductor converter module, were investigated by a few experts for CL purposes [43][44][45][46]. As shown in Figure 19, SSSC has the same H-bridge structure as a static synchronous compensator (STATCOM), but uses series-connection rather than paralleled connection [47].…”

“…SSSC may be a good multi-functional flexible fault current limitation component solution. Static synchronous series compensators (SSSC), as a series-connected semiconductor converter module, were investigated by a few experts for CL purposes [43][44][45][46].

Impacts of the SSSC control modes on small-signal and transient stability of a power system

“…Studies of using SSSC for improvement 0378 of the dynamic behavior of the system are reported in [8][9][10]. In this work, the steady-state and dynamic SSSC controls are jointly considered in a simple power system.…”

“…2. Note that the SSSC voltage V s changes only the magnitude of the current but not its angle [9,10]. When V s = 0 (Fig.…”

A survey on configurations of current-limiting circuit breakers (CL-CB)

“…With the controlling of gate signal of IGCT instead of just switching, the fault current of this fault current limiter can also be controllable. From 2000 until now, static synchronous series compensators (SSSC) is mentioned in several papers a fault current limiter [39][40][41][42] for power transmission and distribution. SSSC is a similar configuration of static synchronous compensator (STATCOM).…”
