Modelling and simulation of voltage source converter-based interphase power controller as fault-current limiter and power flow controller

Abstract

In this study, a new FACTS device is proposed, which is based on the topology of the conventional interphase power controller (IPC). The proposed topology replaces the conventional phase-shifting transformers (PSTs) with the static synchronous series compensator. The equivalent circuit model for this new voltage source converter-based IPC (VSC-based IPC) is developed. Although the injected voltages of SSSCs are almost perpendicular to the branch currents and cannot maintain a constant amplitude line voltage as PSTs, it is shown that the VSC-based IPC can effectively control the line power flow, without exceeding the line voltage regulation limits. Based on the simulations, the abilities of the device for the short-circuit current mitigation and power flow control are presented for the Iran electric network.

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].…”

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).…”

“…The fourth family is the IPC based on series converter where the DC link voltage is controlled by series converter. This category of the IPC uses the static synchronous series compensator (SSSC) [18,19].…”
