“…The time period in a cycle during which the converter pole voltage is zero is 4β ω 0 . The three-level converter topology greatly reduces the harmonic distortion on the ac side [5], [8], [9] and [10]. Here the STATCOM is realized by a combination 24-pulse three level configuration.…”

A STATic synchronous COMpensator (STATCOM) is a shunt connected voltage source converter (VSC) based FACTS controller using Gate Turn Off (GTO) power semiconductor devices employed for reactive power control. The operation principal is similar to that of a synchronous condenser. A typical application of a STATCOM is voltage regulation at the midpoint of a long transmission line for the enhancement of power transfer capability and/or reactive power control at the load centre. This paper presents the modeling of STATCOM with twenty four pulse three level VSC and Type-1 controller to regulate the reactive current or the bus voltage. The performance is evaluated by transient simulation. It is observed that, the STATCOM shows excellent transient response to step change in the reactive current reference. While the eigenvalue analysis is based on D-Q model, the transient simulation is based on both D-Q and 3 phase models of STATCOM (which considers switching action of VSC).

“…However, generator shaft of a thermal plant has a great opportunity to exchange sub-synchronous energy with the series compensation capacitor and then sub-synchronous resonance (SSR) occurs [4][5][6][7][8]. Since electric strength between AC Buses, which is decided by short-circuit capacity of an equivalent system, can change the resonance frequency of the system and damping characteristics of SSR [9][10][11][12], at the system planning stage it is critical to ensure the short-circuit capacity does not make contributions to exciting SSR.…”

Abstract-This paper proposes a fast method to determine short-circuit capacity for an AC system, which includes a compensation capacitor, to avoid sub-synchronous resonance (SSR) risk at a system planning stage. Firstly, the compensation impact factor (CIF) is calculated for generators with different short-circuit capacities. If CIF of all generators are below the threshold value, then the short-circuit capacity is the safety one. Finally, safety short-circuit capacity group is formed and strongly suggested to the system planning due to no SSR risk threating the system. The proposed method needs simple system modeling and calculation process and little information on generator shaft. Simulation results show that the proposed method can precisely determine the safety short-circuit capacity group for the system.

“…CrossCheck date: 8 February 2017 FACTS like static synchronous compensator (STAT-COM) and static synchronous series compensator (SSSC) have been used to mitigate SSR in previous literatures [14][15][16]. Equipped with back-to-back voltage source converters (VSC), proper supplementary control of UPFC can be used to enhance the stability of the power system [17].…”

Control strategy of unified power flow controller (UPFC) utilizing dq decoupling control is deduced in this paper, which can closely follow the control orders of the active and reactive power. The subsynchronous resonance (SSR) characteristics of a series compensated system equipped with UPFC are studied, and the results reveal that SSR characteristics of the system may vary significantly with UPFC in service or not. Consequently, supplementary subsynchronous damping controller (SSDC) for UPFC is proposed and investigated, and the effectiveness of the proposed SSDC is verified by damping torque analysis and time domain simulations.
