In the first step, given power factor of each load node is predetermined and then capacitor at the load node is calculated based on the known power factor, active power, and reactive power of the load. In the second step, the total compensation power of all capacitors at electric loads is determined.
This may include improved voltage profiles, improved power factor, enhanced stability performance, and improved transmission capacity. The reactive devices are connected either in series or in parallel (shunt). Series capacitors are utilized to neutralize part of the inductive reactance of a power network.
Limit of Capacitors The reactive power of all capacitors placed in a system must be limited as the following inequality: where Qcapc is the generation of the c th capacitor; and is the maximum generation of all capacitors.
Compensation 4.1 Introduction The term compensation is used to describe the intentional insertion of reactive power devices, capacitive or inductive, into a power network to achieve a desired effect.
