Power Factor Control refers to the management and maintenance of an acceptable power factor in electrical systems. Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical circuit. A low power factor indicates that the circuit is inefficient and requires more current to deliver a given amount of power. This results in increased energy losses, higher electricity bills, ...

Static VAR Compensator At the medium voltage level, one common of reactive power compensation is Static Var Compensators (SVCs). SVCs are typically installed in electrical power systems to regulate the voltage and compensate for reactive power fluctuations. They consist of various components such as thyristor-controlled reactors (TCRs) and thyristor-switched capacitors (TSCs) that can quickly adju...

Power factor is an important technical indicator of the power system. It represents the ratio of active power to apparent power in an AC circuit. This ratio is usually expressed as a cosine function (cosφ). The size of the power factor reflects the energy utilization efficiency of the power supply output. If the power factor is too high, that is, the reactive power is too low, it will reduce the r...

The low-voltage power distribution system consists of a distribution substation (usually reducing the transmission voltage of the power grid to the distribution voltage), a high-voltage distribution line (i.e., a voltage above 1 kV), a distribution transformer, a low-voltage distribution line (a voltage below 1 kV), and corresponding control and protection equipment. Generally includes: Main equip...
