Hybrid Power Factor Correction
The Industry
Hybrid Power Factor Correction adopts the configuration scheme of combining Advanced Static Var Generator and switching capacitor/reactor, and implements different reactive compensation schemes according to the actual needs of users on site, so as to achieve the best combination of price and effect.
Hybrid Power Factor Correction consists of two parts: Static Var Generator and switching capacitor / reactor reactive compensation unit. In Hybrid Var Compensator, each unit is designed and produced in the method of low power, small volume and low cost, and both of them are optional, and can be combined in the best and flexible way according to the actual reactive state of the site, so as to achieve the optimum ratio of operation effect and cost.
Background
The automobile manufacturing industry is a typical heavy industrial industry, and its electricity demand has many characteristics, such as large power demand, lower power factor of electrical equipment, many typical nonlinear loads and impact load equipment, and high power quality requirements.
Power Quality Problem
The automobile manufacturing industry is a typical heavy industrial industry, and its load is large, and there are also a large number of impact loads, resulting in a rapid load change, so that the traditional capacitor cabinet reactive power compensation cannot keep up with the load change. Considering the cost and practicability, the hybrid var compensation method is generally used for reactive power compensation.
The Hybrid Power Factor Correction consists of two parts - Static Var Generator and switching capacitor&reactor reactive power compensation part. For large-capacity, fixed reactive power, configure switching capacitors for compensation; for small-capacity, fast-changing reactive power, configure corresponding static var generator capacity for compensation; ensures switching accuracy And the response speed at the same time improves the service life of the equipment.
Solution
Yibin Kaiyi Automobile Co., Ltd. is the leading engine for Yibin to build a 100 billion-level automobile industry, and a pillar enterprise of vehicle production in Sichuan Province. In order to ensure the power quality of the enterprise, a large number of hybrid var compensators are installed in the park for reactive power management. The following is a set of 200kvar SVG+Hybrid Power Factor Correction. After the equipment is running, the on-site power factor rises from 0.90 to about 0.99.
