1. Compensating for reactive power can increase the proportional constant of active power in the power grid.
2. Reduce the design capacity of power generation and supply equipment, and reduce investment. For example, when the power factor cos Φ=0.8 increases to cos Φ=0.95, installing a 1Kvar capacitor can save 0.52KW of equipment capacity; On the contrary, increasing 0.52KW is equivalent to increasing the capacity of the power generation and supply equipment for the original equipment. Therefore, for new construction and renovation projects, reactive power compensation should be fully considered to reduce the design capacity and thus reduce investment.
3. Reduce line loss by using the formula Δ Ρ%=(1-cos θ/cos Φ) × 100%, where cos Φ is the power factor after compensation and cos θ is the power factor before compensation
Cos Φ>cos θ, therefore increasing the power factor also reduces the line loss rate. Reducing the design capacity, decreasing investment, increasing the proportion of active power transmission in the power grid, and reducing line loss all directly determine and affect the economic benefits of power supply enterprises. Therefore, power factor is an important indicator for assessing economic benefits, and it is imperative to plan and implement reactive power compensation.
