Series capacitor compensation has been applied for transmission systems to increase the system capacity and enhance its voltage profile. In distribution systems, the main advantage of the series compensation is its voltage boost to the buses downstream from where the capacitor is positioned. Such compensation is proportional to the load current and depends

Series capacitor compensation technology can significantly increase the transmission capability, so it is widely used in long-distance high voltage power transmission. At the same time, there is a risk of inducing subsynchronous and super-synchronous oscillation. The impedance-based analysis method is an effective method to study such phenomenon.

The effects of a fixed capacitor-bank and an SVC have been analyzed regarding their benefits to an uncompensated power supply system. The input data of the conducted simulation model had been taken from an experimental measurement in the Electrical Machines Laboratory of VIT University Vellore (India).
To supply this reactive power, two capacitor banks are connected in parallel via externally monitored circuit breakers for each phase. A feedback loop is designed to automatically turn on the capacitor banks whenever there is an increase in the load current and a reduction in the power factor, as shown in Figure 4.
This paper discusses the Static VAR Compensation (SVC) method as an effective solution for power factor improvement. The need for power factor correction arises to regulate the system voltage and reactive power flow in an electrical system.
Further as load 2 turns on, capacitor bank 2 also turns on along with 1 to provide compensate the dip in the power factor. Therefore, when both the loads are switched in the circuit, all the capacitor banks are active thus providing full compensation to the system and correcting the power factor to 1.
Firstly the behavior of a fixed mechanically switched capacitor bank is observed and secondly thyristor switched capacitors (TSC) and thyristor controlled reactors (TCR) are modeled for static VAr compensation (SVC).
When the capacitive reactive power starts increasing, i.e. in case of overcompensation, the thyristors of the TCR are turned on by getting a signal from reactive power monitor. Therefore capacitive reactive power is balanced . The waveform of active and reactive power and power factor is given in Figure 7.
