Capacitor bank installed in parallel with PV on-grid can be used to compensate reactive power locally. This paper discusses the impact of using VSC controls on the inverter and capacitors bank installed in parallel on the PV on - grid 122 kWp which interconnected with a local load of 150 kVA and has a power factor of 0.7.
Capacitor banks are frequently used in power plants, substations, industries, and certain residential areas to increase the dependability and effectiveness of electrical systems. Figure 2: A Capacitor Bank To understand the workings of a capacitor bank, it is essential to know about its construction and various components.
In capacitor there are two conductors with equal and opposite charge say +q and –q. Thus q is called charge of capacitor and the potential difference is called potential of capacitor. Let A be the insulated conductor with a charge of +q units. In the absence of any other conductor near A charge on A is +q and its potential is V.
Industrial and domestic loads, powered through substations, also have inductive loads majorly. Such loads pull down the power factor as explained above, decrease efficiency, and cause power loss. A sizable capacitor bank is added to the system to counteract this effect. While the inductor causes power lag, the capacitor causes power lead.
Capacitors are the most important part of capacitor banks, as their name implies. When needed, these capacitors release the electrical energy they have stored. These capacitors are connected in series and/or parallel to increase the total capacitance and energy-storing capacity. Resistors are among the most crucial components in a capacitor bank.
Application of the developed negative-sequence current difference method for theunbalance protectionof the capacitor banks enables to achieve a compact and cost-reduced design of the banks connected in parallel to PV power plants.
