The series capacitor provides fixed series capacitive compensation and it may not be suitable if there are changes in the power network configurations (i.e., outage of lines/network). In such cases, the TCSC can be applied to vary the compensation level depending on the network requirement or configuration.
The main reasons to use gate-controlled series capacitor (GCSC) as new controlled series compensators are to enhance power transfer capacity and improve transient stability by mitigating sub-synchronous resonance (SSR) and damping power oscillations [27 – 29].
The fixed series capacitor compensation can produce SSR problems (i.e., oscillations at sub-synchronous frequencies and instability) when it interacts with the generator-shaft torsional systems. The TCSC gives a better response in damping such oscillations and providing stability.
The objective of series capacitive compensation is to vary (or reduce) the overall effective series transmission reactance between the sending and receiving ends. Thyristor-controlled series capacitor (TCSC) provides variable series capacitive compensation using the thyristor firing (or delay) angle control.
Notwithstanding the fact that switched capacitors were first introduced to damp SSR, they improve the performance of the grid in terms of reactive power compensation, voltage stability, transient stability, power oscillation damping, and SSR damping as described in the following.
