According to the standards, the maximum capacity of each group of capacitor should not be greater than 8 Mvar in 10 kV voltage level, not be greater than 12 Mvar in 35 kV voltage level, and not be greater than 20 Mvar in 110 (66) kV voltage level.
Compensation capacitors are installed in numerous locations in electrical installations. They are to be found in high voltage transmission and distribution systems, in transformer substations and also at various levels in low voltage installations.
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 feasibility of compensation capacity configuration scheme is verified through multiple wind farm calculation cases. The purpose of flexible control of voltage and reactive power can be obtained with the reasonable capacity configuration for wind farm reactive power compensation devices.
