6 FAQs about [Can energy storage capacitors be used for reactive power compensation ]

What is reactive power compensator?

Reactive power compensators: To control the system voltage, an additional reactive power is supplied to the system. Such devices are called reactive power compensator. Compensation cost: Cost asked by the power seller for providing the compensation in system.

Can STATCOM be used for reactive power compensator?

But, as soon as the disturbances occur in IHES at t = 1 s, FC alone is not capable to support the system for this dynamic compensation requirement. On the other side, if cost of compensation is not a constraint for adopting reactive power compensation method, STATCOM can alone be used for providing reactive power compensator.

Can a fixed capacitor be used as a reactive power compensator?

To verify this statement and to check any feasibility of using single static compensators for dynamic changes, only fixed capacitor is connected as reactive power compensator. A simulink model is developed in MATLAB simulink toolbox window for the IHES components as shown in Fig. 4 except the STATCOM block.

How does a capacitor provide reactive impedance?

Capacitor provides reactive impedance that causes proportional voltage to the line current when it is series connected to the line. The compensation voltage is changed regarding to the transmission angle δ and line current. The delivered power P S is a function of the series compensation degree s where it is given by

How does a capacitor switched compensation system work?

The controller, after some calculations, decides on the capacitor stages closest to these powers and activates them. However, after the capacitors are switched on/off, unlike conventional capacitor switched compensation systems, the reactive powers drawn from each phase of the grid must be of the same type.

Are switched capacitors cost-effective?

Although switched capacitors are cost-effective, it is almost impossible to achieve full reactive power compensation with them. Other tools that their reactive power outputs are fully controllable are expensive solutions.
