Capacitor banks are critical components in substations, playing a pivotal role in maintaining power quality and stability within electrical distribution systems. These devices consist of multiple capacitors connected either in series or parallel, functioning as a unified system to store and release electrical energy as required.
Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.
The major aim of designing parallel–parallel compensation systems is the implementation into one structure as many functions as possible. This is well-established in modern distribution systems where the nonlinear loads and external weather phenomena deteriorate power quality (PQ).
Voltage mode parallel active compensators have one significant disadvantage: the power factor depends on the load’s active power and line voltage. This causes PF deterioration, especially in the case of line voltage dips and swells (although the load voltage in PCC still is stable).
Maintenance Requirements: Regular maintenance is necessary to ensure the long-term reliability of capacitor banks. This includes periodic inspections to check for signs of wear or damage, such as bulging capacitors or leaking dielectric fluid.
These banks consist of multiple capacitors connected either in series or parallel, functioning as a single unit to store and release electrical energy. By offsetting inductive loads, capacitor banks enhance system efficiency and reliability. Shunt capacitors are connected in parallel with the load.
